Dew Point Sensor

Dew Point Sensor

Measuretest Instruments offers Dew Point Sensor. 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 °C. 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. 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.
