S 201 Dew Point

SUTO-iTEC dewpoint sensor/ dew point transmitter S 201

The measured dew point is output via a 4-20 mA signal output. The integrated display shows online measurement values and alarm status. One alarm can be programmed which will activate a relay.
S 201 features a complete dew point meter with sensor, display, keyboard and alarm.
Sensor parameters such as analogue output scaling, alarm values, units etc, can be easily changed by using SUTO-iTEC service kit. This kit is used to connect the sensor to a PC for configuration changes.
