3 pplication
The S201 is a dew point sensor which is designed to monitor the dew
point in industrial application within the permissible operating
parameters. These parameters can be found in the technical data
section.
The S201 can measure the following values:
•Temperature of the compressed air or gas.
•Humidity of the compressed air or gas.
•Dew point of the compressed air or gas.
The default factory settings are: temperature in °C, Humidity in % rH
and dew point in °C Td. Other units can be programmed by the optional
display or the service kit.
The S201 dew point sensor is not developed to be used in explosive
areas. For the use in explosive areas please contact the manufacturer.
The S201 dew point sensor is mainly used in compressed air systems in
industrial environment.
