S 220

S 220 Dew point sensor (-100 ºC ... 0 ºC)

The SUTO dew point sensor S 220 provides reliable and long term stable dew point monitoring in industrial applications.
SUTO is using a new sensor technology which has superior signals at very low moisture levels thus providing reliable measurements down to –100 ºC.
 
A stainless steel sinter filter with pore sizes below 30 μm protects the sensor from particles. It’s designed for applications where  very low moisture levels needs to be detected.
 
The measured dew point is output through a 4-20 mA signal (3-wire or loop powered). Sensor parameters such as analogue output scaling, physical units, can be easily changed by using SUTO service kit.
