HYGRASGARD
Series HYGRASGARD ® ESFF / ESFTF humidity sensors are used for measuring
the relative humidity and temperature of air in pressure systems and convert
these measured values into standard signals of 0 - 10 V or 4...20 mA. Process
connection by G ½" straight external pipe thread, with terminal box enclosure
made of impact-resistant plastic and enclosure cover with quick-locking screws.
These screw-in humidity sensors are to be operated in pollutant- free non-
precipitating air, mounted vertical with the sensor pointing down.
