3 Application
3 Application
The S220 OEM Dew Point Transmitter is an industrial instrument
designed for measuring dew point and related parameters in
compressed air or industrial gases under specified operating conditions
(See next page ).
Parameter Default unit
Temperature °C
Humidity % rH
Dew point °C Td
Pressure (optional) bar (g)
Remark: You can change the units using the service
kit (optional) or the S4C-DP mobile App.
The S220 OEM Dew Point Transmitter is mainly used in compressed air
systems in the industrial environment, and not developed to be used in
explosive areas. To use it in explosive areas, please contact the
manufacturer.
4 Features
•The Dew Point Transmitter S220 is applicable for measuring down
to -100°C Td.
