4 Application
4 pplication
The S230/S231/S230 Ex/S231 Ex is a dew point transmitter which is
designed to monitor the dew point in hazardous environments and
industrial application within the permissible operating parameters.
The S230/S231/S230 Ex/S231 Ex measures the following values:
•Dew point of the compressed air or gas.
•Temperature of the compressed air or gas.
•Other selectable moisture units such as: relative humidity [% rH],
absolute humidity [g/m3, mg/m3], humidity grade [g/kg], humidity
ratio by volume [ppmV] of the compressed air or gas.
The default factory settings are: temperature in °C and dew point in
°C Td. Other units can be programmed by the service kit.
5 Features
•Double sensor technology for best accuracy over the whole range
from 100°C ... +20°C Td dew point in S230 and S230 Ex
•Robust industrial design
•Outputs: 1 x 4 ... 20 mA, RS 485 (Modbus).
•IP67 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
•High accuracy
