Application
3 pplication
The SUTO dew point sensor S217-OEM provides reliable and long term
stable dew point monitoring in industrial applications. The newly
developed sensor features improved signal and stability in demanding
industrial applications.
It’s designed for OEM applications in desiccant and refrigeration dryers.
The measured dew point is output via the loop-powered 4 ... 20 mA
signal. Sensor parameters such as analogue output scaling, physical
units, can be set e factory.
4 Features
•Small size makes it ideal for dryer installations
•Measures dew points down to –50ºC Td
•2-wire loop powered sensor or 3-wire
•Modbus/RTU signal output (model depending)
•IP65 casing provides robust protection in rough industrial
environment
•Very fast response time ensures safe and relia-ble indication
whenever dew points are out of valid ranges
•Can be installed directly into dryers through G 1/2” thread
•High accuracy of 1 … 2ºC Td dew point
•Withstands condensation
•Can be supplied with connection cable attached
•M8 connector and cable with open wires
