AES Ignition/Detection System Overview: The spark emission system features a computer-controlled power source that allows for control of the spark frequency and the spark current. These are important parameters, which are optimized at the time of system manufacture, and they help to define the rate of electrode consumption and the light output of the source. All of the control parameters can be redefined at anytime and can be readjusted as required in the field, either directly or indirectly by remote communication. The spark, which is nominally modulated at 300 Hz is struck between a pair of vertical non-interfering metal electrodes, with the sample flowing over the lower of the two electrodes. The light from the emission is collected by an imaging system and is transferred to the spectrometer system via high-grade, UV-quality fiber-optic cables...

5 ~ 5 ~ 4. IR Filter Wheel Detection System Overview: The IR Module uses a mid-infrared spectroscopic analysis technique to differentiate and quantify the components in an oil sample, based on sample spectral absorbance pattern and characteristic absorbance peaks. The module uses a proprietary set of optical band-pass filters to measure the amount of energy that is absorbed by an oil sample at these identifying peaks. The amount of light absorbed is proportional to the concentration of the component(s) in the oil sample. The module utilizes a temperature control system to maintain the spectroscopic systems at an optimal operating temperature. Depending on ambient conditions, the temperature control system may heat or cool the internal optic assembly. The temperature control system can maintain optimum temperature within the analyzer when the temperature is between 60 and 90 degrees F. As the sample is introduced into the OSA, it is directed to the IR module and collected in a cell. The sample flow is stopped, the filter wheel is rotated to each of the pertinent 15 filters, and scans are taken based on the application selected. Closed-cell configuration Multiple filters for specific physical property measurements 5. (Optional) Dual-Temperature Viscometer System Overview: The Dual Temperature Viscometer (DTV) works on the principle of over-pressure. Sample oil is pumped into a reservoir chamber, then blown out, at constant pressure, through a precision tube at the bottom of the chamber. The time to blow out a sample is directly related to the sample s viscosity and can be calculated from the time measurement. Dual chambers (temp-regulated to 40C and 100C) Calculated Viscosity Index Constant pressure, fixed-volume analysis 6. (Optional) Particle Counter system Overview: The Particle Counting System is fully integrated with other components of the OSA analyzer. Particle analysis and sensor cleaning are carried out by background tasks and operate seamlessly with other analysis on OSA, which does not add extra time to regular OSA cycle time. Operator has the flexibility to enable/disable particle counting system for each analysis. Operator shall degas the sample before analyzing it. An ultrasonic bath is shipped with OSA analyzers equipped with particle counting system. 100mL-based analysis ISO 4406:1999 ISO-code reporting Sample Requirement: Total Sample Volume: 150 ml (5 oz). Sample Viscosity Range: up to 320 cst. Sample preparation: Degas procedure is recommended per ISO Analyzing Time: Total Cycle Time: minutes, depending system configuration and sample viscosity. 7.

High Range accuracy is diminished compared with Low Range because of expanded dynamic range and corresponding lower signal-to-noise ratio. 2. Accuracy values reflect typical conditions of use and anticipate mutual spectral interferences among elements where likely.
