3 Application
The SUTO Dew Point Transmitter S217-OEM provides reliable and long
term stable dew point monitoring in industrial applications. The newly
developed transmitter 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. 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 –60ºC 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 reliable 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

Explanations of MSB and LSB
MSB MSB refers to Most Significant Byte first, which follows the Big-
Endian byte order.
For e ample, if the main system follows the MSB first order:
When the 4-byte floating number, in the order of Byte1-Byte0-
Byte3-Byte2, is received from the slave (sensor), the master
must change the byte order to Byte3-Byte2-Byte1-Byte0 for the
correct display of the value.
