3 1 Introduction PM-616 two-color infrared pyrometer is primarily used in the metallurgical industry to measure temperature of steel or molten iron, wire rod, hot rolled steel, as well as cement kilns. The pyrometer can look into a process and measure the target temperature from a distance, providing an accurate reading while eliminating problems associated with contact measuring devices. Dual infrared wavelengths input signals overcome application challenges such as small targets, variable emissivity, dust, water or other interfering media between the target and the pyrometer. Accurate temperatures are obtained even when the target is 95% obstructed. PM-616 pyrometer also has a fiber optic option to utilize in applications with high electromagnetic interference or high temperatures. The lens and fiber optic cable can withstand up to 300 C with air purge connected. 2 Description 2.1 Model Nomenclature PM FOC- 024 Input power supply 24VDC Lens with fiber optic cable Leave blank for standard lens Upper limit temperature 1600 C Lower limit temperature 600 C Logika two color infrared pyrometer Figure 2.1 PM-616 Model Nomenclature P a g e 2

4 2.2 Operating Principle Logika PM-616 pyrometer uses a state-of-the-art photodiode to sense the infrared energy from the target. Our pyrometer measures infrared energy emitted by the target at two wavelengths and calculates the ratio of these measurements to determine the target temperature. Since the emissivity of the two wavelengths is identical in same environment, it does not influence the accuracy of the temperature measurement. The primary advantage of PM-616 over thermocouple temperature measurement is that the pyrometer accurately measures the target temperature by way of non contact means and responses much faster. Compared with single wavelength pyrometers, the advantages of the Logika PM-616 two-color pyrometer are: 1. Overcomes optical fouling or interfering media between the target and the pyrometer, such as dust, dirt, smoke, and water vapor, to yield accurate temperatures. 2. Automatically compensates for changes in target emissivity or varying distances between the target and pyrometer. 3. Almost no restrictions to pyrometer s field of view, leaving more flexibility for pyrometer mounting. The PM-616 can accurately measure the target temperature even with as little as 5% of the field of view. 4. PM-616 can also switch to single color mode for special field applications. The PM-616 also has built-in temperature slope adjustment for calibrating the pyrometer to the specific characteristics of the target metallurgy, and a visible target aiming laser for easy installation.

6 Housing Hermetically sealed stainless steel enclosure rated IP66, includes purge air and cooling water connections. Optional fiber optic lens assembly includes air purge fitting. Size 370mm L X 100mm W X 190mm H (14.5 L X 4 W X 7.5 H) Weight 4 kg (8.8 Lbs) 3 Location and Mounting 3.1 Pyrometer Location Basic installation considerations: Pyrometer should not be installed above heat sources, also avoid directly exposure to water vapor, excessive dust or smoke. If harsh ambient environment is unavoidable, connect clean, dry air to the air purge fitting on the pyrometer enclosure. Heat shielding or fan can also be applied to dissipate water vapor or smoke. If conditions allow, mount the pyrometer as close to the target as possible. This will supply enough infrared energy for the pyrometer to provide strong signal. At the same time, the pyrometer must be kept far enough to protect it from being over heated. Installation distance: depends on color mode selected. o One-color mode: target should be covered by the pyrometer s field of view. Check Figure 3.1 and Figure 3.2 for reference. o Two-color mode: no restrictions to field of view. For example: If the target diameter is 20mm, pyrometer Displacement Coefficient is 50:1 (D/S=50:1). In one-color mode, according to Figure3.1 and Figure3.2, the pyrometer has to be installed less than 1 meter away from the target. In two-color mode, it is not necessary for the target to be totally covered by the field of view, the pyrometer can be installed more than 1 meter away from the target. Maximum ambient temperature for the pyrometer o 50 o C (122 o F) without water cooling o 120 o C (250 o F) with water cooling connected. See Figure 4.2 P a g e 5

Aiming - For standard pyrometer, use the aiming laser to properly align the pyrometer with target. 3.3 Lens with Fiber optic cable Install the lens with supplied mounting bracket. Check the section 3.1 for installation considerations. The maximum ambient temperature for the lens and fiber optic cable assembly is 300 o C (570 o F). Use a laser pen for alignment, see Figure 3.3. The laser spot on the target is for the pyrometer to receive the radiation energy and calculate the temperature, make sure the spot area is flat and no sharp edge.

Purge air cleans the lens, reduces maintenance times, and prolongs pyrometer s life in where dusty or corrosive vapor is present. Purge Air Requirements Must be clean, dry instrument air no oil, dust and contaminants included. Poor air quality will result in dirty lens and decrease pyrometer performance. If the quality of compressed air can t be guaranteed, it should not be connected to avoid lens contamination and affect the pyrometer performance. Air filtration prior to the inlet fitting is recommended to improve the quality of purge air Air Pressure range from 50 to 200 g/cm 2 (0.7 psi to 2.8 psi) Air Flow rate from 4 to 16 L/min (0.14 to 0.56 ft 3 /min) Connection- Connect the plant air source to the purge air barbed fitting on the sensor s lens shroud with Φ10mm ID (or 3/8 ID) hose. Purge air flows out of the sensor shroud and dissipates into the ambient environment. P a g e 10

To reach control panel: Use M2.5 Allen key to remove the back cover from unit Unthread the glass cover on the pyrometer body by turning it counterclockwise!!! When operating on the control panel, please note: o The pyrometer tube may slide out of cooling tube if angled downwards. Keep unit level when disassembling for menu adjustment. o The pyrometer tube is sealed during manufacturing to retain accuracy and quality. Warranty is void if pyrometer tube is dismantled for any reason. 5.2 Set Menu Functions and Programming In display mode: Press to switch between one-color and two-color mode Press to switch temperature display between F and C Figure5.1 Keypad setup sequence Press SET repeatedly to choose setup parameters Press ENTER to display current value Use the arrow key to change the value P a g e 11

13 Press ENTER again to save the new value and EXIT setup Set Menu 1- Emissivity/Slope Adjustment One-color mode: Emissivity setup value Emissivity: The relative ability of target measured surface to emit energy by radiation. It is the ratio of energy radiated by a particular material to energy radiated by a black body at the same temperature. A true black body would have an emissivity = 1 while any real object would have emissivity < 1. By adjusting the emissivity, the pyrometer can accurately measure target temperatures. If the target s emissivity is setup higher than its true value, the measured temperature by pyrometer will be lower than the actual temperature. The emissivity data in the table below is for reference only. Material surface finish can cause varying emissivity. If the metal surface is slightly oxidized and dirty, its emissivity will drop significantly.

Determine actual target temperature with a contact RTD, thermocouple or other appropriate instrument. 3. Press SET button until the display shows 1- (flashing), then press ENTER to adjust the emissivity. 4. Use the up and right arrow buttons to adjust the value. 5. The emissivity adjustment range is from 0.10 to 1.00; in 0.01 increments. For 0.01, results in 1.0 C, factory default value is Press ENTER to save the adjustment and return to the temperature display mode. Two-color mode: Temperature Slope Adjustment (Calibration) Temperature slope is a coefficient to compensate for the two wavelengths emissivity difference. Note: The listed ratios are approximate values and can change with alloy surface condition and oxidization. For these oxide metals, the temperature slope setup value is Cobalt Nickel Iron Stainless steel Steel For these metals, the temperature slope value is Cobalt Iron Stainless Steel Rhodium Tungsten Molybdenum Platinum Steel Nickel Tantalum Cast Iron Slope adjustment allows the user to refine the accuracy of the pyrometer for specific applications. This feature can be used to calibrate the pyrometer. 1. Use a reliable thermometer to measure the surface temperature of the target. If temperature readings vary in different measured areas, use the average reading. 2. Set the pyrometer to work in two-color mode (Mode LED ON) 3. Press SET button until the display shows 1- (flashing), then press ENTER to adjust the temperature slope. 4. Use the up and right arrow buttons to adjust the value. 5. The temperature slope adjustment range is to in increments. For 0.001, P a g e 16

Set Menu 2- Display Mode This feature allows the user to select different temperature display modes; Peak temperature; Valley temperature; or Average temperature values. Peak: Response time setup range from s. If response time is set greater than seconds, the current display will remain unchanged. Applications: Best for moving target temperature measurement (steel plate, sheet). This function can also be used for measuring surface temperature of liquid metal when highest temperature measurement is required. Valley: Response time setup range from s. If response time is set greater than seconds, the current display will remain unchanged. Applications: Best for measuring surface temperature of liquid metals when lowest temperature measurement is required. Average: Response time setup range from seconds. Applications: Most field applications. For example, if there is scale on steel plate or bar, average temperature display mode should be selected. Real time display: Set response time to 0.0s. In this display mode, the sampling time is set 20ms by pyrometer and display changes each time new data is collected. 1. Press SET button until the display shows 2- (flashing). 2. Press ENTER button and use the up arrow button to select display states. Select (1) for Peak, (2) for Valley or (3) for Average.

Calculated current output at measured temperature is Set Menu 9- Aiming Laser Setup Four setups available: OFFd, OFFn, ON d and ON n. See below for details. This function selects whether the laser switch function is open or closed when the temperature limit is exceeded. The function is not available for FOC pyrometer. OFFd: Turns the aiming laser off. It will automatically turn back on when the target temperature is greater than the lower limit setup value. OFFn: Turns aiming laser off. ON d: Turns aiming laser on. After 30 minutes, the laser will turn off if the target temperature is below the lower limit setup value. ON n: Turns aiming laser on. After 30 minutes, laser will turn off. 1. Use SET and ENTER buttons to select the Aiming Laser Switch (Menu 9- ). 2. Use the up and right arrow buttons to change the setting. The factory default is OFFd. 3. Press ENTER to return to the temperature display mode. Display Menu 10- Enclosure Temperature This feature only displays the current enclosure temperature for diagnostic purpose. P a g e 21

23 If the enclosure temperature is higher than 70 o C, the display shows EEE1. If the enclosure temperature is lower than -10 o C, the display shows EEE2. Either of these conditions exists, steps must be taken to adjust the ambient temperature. Display Menu 11- Two Color Ratio This function only displays the ratio of the current two wavelength signals for service diagnostic purposes. Set Menu 12- Zero Compensation Gain This feature is used to adjust the detector gain to compensate for targets with a starting temperature below the specified measurement limits of the Logika PM-616 pyrometer. Use SET and ENTER buttons to select the Zero Compensation Coefficient ( Menu 12- ) The four digit number shows the coefficient; the first number represents the coefficient polarity (1 = positive and 0 = negative). The remaining three numbers show the coefficient value. Use the up and right arrow buttons to change the Zero Compensation Coefficient. This value is always set below The factory default for the Zero Compensation Coefficient code is which equals Press ENTER to return to the temperature detection mode. Plority 1: Positive 0:Negative Coefficient Value X.XX No Use Figure 5.6 Zero Coefficient Gain setup Set Menu 13- Two-color mode signal attenuation ratio Attenuation Ratio = 100% Emissivity (Check Page 11 in Set Menu 1 for Emissivity). Attenuation ratio is a threshold for verifying the validation of the measured temperature. After the target temperature is calculated by the pyrometer, it calculates each wavelength s P a g e 22

24 emissivity at this temperature. For each wavelength, the attenuation ratio (100% Emissivity value) should not be less than the set value. If either one is higher than the set value, the pyrometer displays the lower limit temperature. This function is only used in two-color mode. The setup range is 20%-100% and the default setup value is 95%. If the attenuation ratio is set greater than 95%, this function will shut down; and again, the lower limit temperature will be displayed. For example, if the pyrometer is used to detect the temperature of tungsten filament of a light bar, usually the temperature is higher than 1500 C (2732 F). The tungsten filament (target) diameter is very small at 2mm, so the emissivity would be very low. According to Figure 5.6, if the temperature is greater than 900 C and target size is 2mm, the attenuation ratio should be set to 95%. This means that as long as the emissivity value for each wavelength signal is not less than 5%, the calculated temperature is valid. In this case, the two-color mode, can still accurately calculate the temperature. In single color mode, it would be very hard to get an accurate target temperature in this situation. Table 5.2 Attenuation Ratio Setup Value Target size(diameter) Accurate measurement attenuation ratio Simplified measurement attenuation ratio 2mm-10mm 95% 95% 10mm-30mm 90% 95% 30mm-100mm 80% 95% >100 mm 70% 70% The values above are for reference only when setting up the attenuation ratio. The value should be adjusted depending on application environment and target size. 1. Use SET and ENTER buttons to select the signal attenuation ratio setup ( Menu 13- ) 2. Use the up and right arrow buttons to change the value. 3. Press ENTER to return to the temperature display mode. P a g e 23

(b) If the object is painted black, the emissivity can reach Test the adjacent area, and adjust the slope until the test result is the same as the thermocouple. Now the slope has been properly adjusted. P a g e 24
