Description:

TU.33-34 are active sensors, which measure the relative humidity (RH) and convert the measurement into a selectable voltage signal 0 –10 V or an electric current 4–20 mA. The TU-A transmitters consist in a built-in sensor and amplifier. TU-A are designed for wall mounting.The TU-D transmitter is delivered as a complete unit, comprising an aluminum mounting flange with the sensing element, and an amplifier mounted in a separate housing. TU-D33 is intended for ducts installation and is used for relative humidity measurement in air ducts. The sensor has negligeable hysteresis and it is insensitive to dust as well as most chemicals. TUTA34 and TUTD34 include selectable NTC temperature sensors.
