Dew point sensor
The FAS-SW is a sorption-type, aluminum oxide sensor designed to measure the water dew point over a wide temperature range at an operating pressure of up to 300 bar. Measurement results are then transmitted to the upper level via 4 … 20mA analog output.
The FAS-SW is designed to measure the water dew point in inert and aggressive gases, including those containing hydrogen. It can be used for a wide variety of applications, where the use of a sorption-type aluminum-oxide sensor is preferred to a condensation hygrometer. Areas of application include technological processes in the chemical and petrochemical industries, natural gas processing, and metallurgy. The FAS-SW is equally well-suited for applications in mechanical engineering, microelectronics, and the energy industry.
