S 220 DEW POINT SENSOR/ dew point transmitter (-100 … 0 ºC)
The SUTO-iTEC 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 mesh filter with pore sizes below 30 um protects the sensor from particles. It’s designed for applications where very low moisture levels needs to be detected.
Application
Stated accuracy under following conditions:
- Ambient temperature 23±3°C
- Process temperature 23±3°C
- Ambient humidity <95%, no condensation
- Airflow > 2 l/min at sensor tip
