HMW82 Humidity and Temperature Sensor for HVAC, Wall Model, Current Loop, 3% accuracy.
The 2-wire HMW82 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 HMW82 is designed to fit standard 2x4" junction boxes.
The HMW82 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 HMW82 has two 4…20 mA loop-powered outputs corresponding to 0…100% RH and -5…+55 °C (+23…+131 °F) temperature.
In addition to the active 4...20 mA temperature output there is an option for a passive Pt100 F0.1 IEC 60751 temperature sensor.
