OMEGA Engineering, Inc. Relative Humidity Transmitter HX92A

The model HX92A is an economical humidity transmitter, providing on-site continuous monitoring of relative humidity. It is a 2-wire transmitter with either voltage or current output. The transmitter output is linearized, and RH readings are temperature compensated. A thin-film polymer capacitor senses relative humidity. The sensor is protected by a stainless mesh-type filter that is easily removable for cleaning. The case and weathertight protection, and screws are provided for mounting the unit via internal hole. An unusually low minimum voltage of 6 V allows the use of large impedances for longer wire runs. The HX93A is a similar unit that provides transmitter outputs for both humidity and temperature.
