Suto S217 Dew Point Transmitter for Desiccant and Refrigerated Air Dryer Use. Ensures precise measurement of gas humidity. Ideal for compressor air quality analysis.
SUTO Dew Point Sensor S 217
The SUTO Dew Point Sensor S 217, developed by Hangzhou Xinjian Electronic Co., Ltd., offers reliable and long-term stable dew point monitoring in industrial applications. This sensor features improved signal and stability, making it ideal for demanding industrial environments.
Designed for OEM applications in desiccant and refrigeration dryers, the S 217-0EM sensor utilizes new sensor technology in a compact casing, allowing for cost-effective solutions. This enables its use in smaller dryers and point-of-use dryers, promoting energy-efficient dew point control.
The measured dew point is output via loop-powered 4-20 mA signal or 3-wire 4-20 mA output. Sensor parameters such as analogue output scaling and physical units can be set ex factory, providing flexibility and ease of use.

1. Small size makes it ideal for dryer installations.
2. Measures dew points down to -50°C
3. 2-wire or 3-wire output
4. lP65 casing provides robust protection in rough industrialenvironment
5. Very fast response time ensures safe and reliable indicationwhenever dew points are out of valid ranges
6. Can be installed directly into dryers through G 1/2"thread. 7. High accuracy of 1° .. 2°c dew point
8. Withstands condensation
9. M8/M12 connector and cable with open wires
