TC ** 2 to 1400 (0 to 760) APPLICATION INFORMATION Suitable for vacuum, reducing or inert atmospheres, oxidising atmospheres with reduced life. Iron oxidizes rapidly above 1000 F (58 C) so only heavy gauge wire is recommended for high temperature. Bare elements should not be sulphurous atmospheres above 1000 F (58 C) K Chromel * Tophel * T1 * ThermoKanthal KP * ALumel * Nial * T2 * ThermoKanthal KN * 2 to 200 (0 to 1260) Recommended for continuous oxidizing or neutral atmpspheres. Mostly used above 1000 C (58 C). Subject to failure if exposed to sulphur. Preferential oxidation of chromium in positive leg at certain low oxygen concentrations causes "green rot" and large negative calibration drifts most serious in the F ( C) range. Ventilation or inert-sealing of the protection tubes can prevent this. T Copper Constantan * Cupron * Advance * ThermoKanthal KN * -00 to 700 (-184 to 71) Useable in oxidizing. reducing or inert atmospheres as well as vacuum. Not subject to corrosion in moist atmospheres. Limits are published for sub-zero temperature ranges.

Must be protected with a non-metallic protection tube and ceramic insulators. Continued high temperature usages cause grain which can lead to mechanical failure. Negative calibration drift causedby rhodium diffusion to pure leg as well as from rhodium volatilization. Type R is generally used in industry while Type S is general used in laboratories. Similar to type R & S but output is lower. Also less susceptible to grain growth and drift. M Nickel 18% Nickel Molybedenum 2 to 2250 (0 to 1287) High temperature applications in inert or vacuum atmospheres. Usefull in many hydrogen applications. Continuous cycling causes excessive grain growth. C 5% Tungsten Rhenium (W-5Re) 26% Tungsten Rhenium (W-26Re) 2 to 4200 (0 to 215) Very high temperature applications in inert or vacuum atmospheres. Preferred over Tungsten/26% Tungsten Rhenium because it is less brittle at low temperatures. W % Tungsten Rhenium (W-Re) 25% tungsten Rhenium (W-25Re) 2 to 4200 (0 to 215) The ductility of WR leg is superior to pure Tugnsten, but not as good as W5Re.

15 THERMOCOUPLE SELECTION Selecting the proper thermocouple and installing it correctly with provide you with more accurate results and give the devise a longer life time. The following are some helpful tips for selecting and maintaining thermocouples. A. Thermocouples should be protected. Many external factors can affect the composition of the thermocouple materials causing skewed readings and shortened lifetime. Evaporation, oxidation, contamination, corrosion, diffusion, and induced EMF must all be considered when a thermocouple is being put into service. Protective sheaths can be used in the construction to protect the device. If the thermocouple contains a bare wire, it is important that the protection tubes are clean and have the proper diameter and length to allow proper ventilation inside. B. Select practical and large wire. Wire that contains heavier wire is often more stable in a high temperature environment when compared with a lighter gauge. However, fine gauge wire provides rapid response and flexibility. A compromise must be made using these factors to determine the largest wire possible to meet the specifications. C. Select proper location for installation. Thermocouple must be installed in an area that properly represents the temperature of the equipment or substance that is being measured. D. Ensure proper thermocouple depth. Since heat can be transferred away from the thermocouple sensor, it is important to ensure the thermocouple has sufficient depth to gain an accurate reading. E. Maintain a constant immersion depth. Imperfections in the thermocouple wires can result from factors such as oxidation, corrosion, and evaporation. These imperfections can cause inaccurate readings if the depth of the thermocouple is altered. F. Heating cycles can affect accuracy. It is recommended that the thermocouples be used at a single temperature or increasingly higher temperatures to maintain high accuracy. However, this is not always the case. It must be accounted for that there will be some error when cyclic heating occurs. The error can be reduced by using thermocouples which are still in good condition. G. Check equipment regularly. It is important to check and repair the thermocouples, protection tubes, and extension wires for any damage. Checks should occur as frequent as necessary, however, once a month is usually sufficient. Check to see if the protection tubes are burnt out or damaged to prevent harm to the thermocouple. Check thermocouples in place if possible. If not, they should be reinserted to at least the same depth to avoid error. Make sure the external wire reaches the resistance equipment. ISOLAB INC. PH: ISOLAB & FAX :

16 TROUBLE-SHOOTING If a thermocouple is giving erroneous readings, the following steps should be taken to spot the error. A. Check Circuit Check the polarity of the thermocouple at each connection. They can often be identified by magnetism or colour coding. The negative thermocouple wire should connect to the negative extension wire, and in turn, to the negative side of the meter. This should also be true for the positive connections. B. Check Instrumentation After checking the circuit, turn your attention to control meter or recording instrument. Make sure the instrument in set to the proper thermocouple type. Check the room temperature setting (cold junction compensation). Do this by removing the extension wires and placing a jumper wire across the meter connection terminals. The reading should coincide with the room temperature. If problems still arise, compare the reading of a test thermocouple with known accuracy (also connected to a meter of known accuracy) with the thermocouple in question. Make sure the test thermocouple is placed as close to the original as possible to ensure they are measuring the same temperature. C. Check Thermocouple Thermocouples are always susceptible to a change in composition which could cause faulty readings. This could be due to many factors such are oxidation, corrosion, or contamination that often come from such things as brazing alloys and fluxes. Check the working thermocouple by hooking it up to a test meter of known accuracy. If the working meter reading is the same as the previous test reading of known accuracy, then the working thermocouple is not the problem. D. Test Meter and Extension Wires Connect the extension wires to a test thermocouple of known accuracy and observe the reading. If the reading is different than obtained with the test meter, then the fault lays in either the working meter or extension wires. Checking all of these components of the system can often result in diagnosing the problem and finding a solution. If the error is directly due to a faulty thermocouple, then it should be removed and inspected. If the thermocouple is severely corroded or oxidized then it should be replaced. It is often better to replace an inaccurate thermocouple than to risk a loss or product or time due to temperature problems. ISOLAB INC PH: ISOLAB & FAX:

17 CAUSES OF AGING (DRIFT) Aging refers to a positive EMF shift (more output) of nickel thermocouple alloys resulting from a temperature gradient along the thermocouple elements. The temperature that aging occurs is estimated to be around 70 to 540 C (700 to 1000 F). There are a few things that can increase the amount of EMF shift: - The temperature that is being measured or the previous thermal history of the thermocouple. - The thermocouple composition. - Duration of aging temperature. - Amount of thermocouple exposed to the aging temperatures. It must be recognized that aging depends on the application for which the thermocouple is being used and the temperature gradient it experiences. The operating temperature of the thermocouple should be checked. If the thermocouple has never been exposed to aging temperatures, it should never have errors due to aging. To reduce the inaccuracy of reading temperatures in the aging range, a preaged thermocouple may be used. Pre-aged thermocouples are heat treated and have special compositions to minimize errors caused by aging. However, if these are heated above the aging range then the effect of the pre-aging can be removed. For applications where the temperature is above the aging range, it is important to keep as little length of thermocouple as possible in the aging range. This will help to minimize the aging effects. The effects of the aging process can actually be removed. This is done by heating the entire thermocouple above 870 C (1600 F) for at least 5 minutes. Then the thermocouple should be rapidly cooled to below the aging temperatures. This should restore the wire to its original calibration. ISOLAB INC. PH: ISOLAB & FAX:

18 HOT OR MEASURING JUNCTIONS Ungrounded Junction (U) The welded thermocouple junction is fully isolated from the welded closure of the sheath. This junction provides electrical isolation to reduce problems associated with electrical interference. Ungrounded junctions are also recommended for use in extreme positive or negative temperatures, rapid thermal cycling and for ultimate corrosion resistance of the sheath alloy. All ungrounded junctions exceed 100 megaohms 100V dc at ambient room temperatures. Exposed Junction (E) The thermocouple wires are welded and exposed. The insulation is not sealed against liquid or gas penetration. Recommended where fast response is desired, and corrosive conditions are nonexistent. The exposed hot junction length for 1/8-inch diameter sheaths and above is typically equal to the outside diameter of the sheath. The exposed junctions for sheath diameters less than 1/8-inch diameter are supplied as sheilded junctions. Grounded Junction (G) The thermocouple junction is welded securely into the closure end of the sheath, becoming an integral part of the weld. This is a good general purpose, low cost junction providing faster response times than an un-grounded junction of similar sheath diameter. Grounded junctions should not be used with Type T thermocouples, due to the copper wire. ISOLAB INC. PH: ISOLAB & FAX:
