The 3-wire HMW83 transmitter is designed for use in energy management systems in buildings. It combines excellent stability with reliable operation. It is easy to install: wire it to the terminal block at the transmitter bottom and close the housing with a snap-on lid to cover the electronics. The HMW83 is designed to fit standard 2x4" junction boxes. The HMW83 uses the interchangeable Vaisala INTERCAP® sensor which requires no recalibration when the sensor is replaced. The sensor is also insensitive to dust as well as to most chemicals.
The HMW83 has two 0…10 V outputs corresponding to 0…100% RH and -5…+55 °C(+23…+131 °F) temperature.
