2. Application
2. Application
The S 212 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 S 212 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 % and
dew point in °Ctd. Other units can be programmed by the optional
display or the service kit.
The S 212 dew point sensor is not developed to be used in explosive
areas. For the use in explosive areas please contact the manufacturer.
The S 212 dew point sensor is mainly used in compressed air systems in
industrial environment.
3. Features
•Dew point sensor for low dew point applications down to -50 °Ctd.
•Long term stability.
•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 dryer through G ½” thread.
•High accuracy of ± 2°Ctd dew point.
