HYGRASGARD® ESFTF-U LCD

Calibratable HYGRASGARD® ESFTF screw-in sensor in a housing made of impact-resistant plastic with quick-locking screws, with cable gland (optional M12 plug connector to DIN EN 61076-2-101), threaded duct pipe (G1/2") and metal sintered filter (replaceable).

The sensor is used to measure relative humidity (0...100 % RH) and temperature (4 switchable measuring ranges) in compressed air lines up to max. 10 bar. The transducer converts the measured variables into a standard signal of 4...20 mA or 0 - 10 V. Further parameters are calculated internally from the measured variables and can be called up via the humidity output: absolute humidity, mixing ratio and dew point temperature (switchable via DIP switch).
The device also has a sensor protection function for high humidity (95...99 % RH). The measuring element is automatically heated in the critical range and thus protected against condensation. The sensor is calibrated at the factory; fine adjustment by a specialist is possible depending on the environment. It must be installed vertically with the humidity sensor facing downwards.
