General Eastern Model SSM-1 Sampling Module - Chilled Mirror Hygrometer
For many applications, a sampling system is required to extract and/or condition a gas sample prior to its contact with the chilled mirror sensor. For example, if the gas temperature exceeds the maximum sensor temperature rating, a sampling system with a 5 ft (1.5 m) coil of copper or stainless steel tubing* upstream of the chilled mirror sensor will reduce the gas sample temperature to ambient and protect the sensor.
The use of a sampling system often provides better, more reliable. long- term dew/frost point measurements for the following reasons:
I. The sample gas can be filtered ti remove undesirable solid and liquid particulates before they contaminate the sensor.
2. The flow rate can be measured and controlled at the optimum rate for the chilled mirror sensor and the application.
3. Measurements of high temperature (e.g. furnace) gases can be made by cooling the sample gas while being careful to avoid condensation in the sampling system.
4. Dew points higher than ambient temperature can be measured using a heated sampling system and/or individually heat-traced components.
It is important to remember that the sampling system must not affect the water vapor measurement in any way. Thus system temperature is critical as well as wetted materials in contact with the scruple gas. Also, it Is Important to keep sample systems as simple as possible, in order to avoid excessively long response times. General Eastern manufactures a variety of sampling systems, modules, and components. Our Applications Engineering Staff will be happy to work with you in designing and specifying the proper sampling system for your application.
