Dew point transducer
FAS-SW
The FAS-SW moisture transducer is an aluminum oxide sorption-type humidity sensor designed to measure the water dew point over a wide temperature range at operating pressures up to 300bar.
Measured humidity values can be transmitted to the upper level by analogue output currents between 4 and 20mA.
Purpose
The FAS-SW is designed for the measurement of moisture in inert and aggressive gases, including hydrogen-containing gases.It can be used in technological processes associated with natural gas processing, metallurgy, mechanical engineering, the chemical and petrochemical industries, microelectronics, the power industry, and where an aluminum oxide sorption-type dew point sensor is preferable to a condensation hygrometer.
