Vaisala HMW92, HMW93, HMW95 Wall Mount Humidity and Temperature Transmitters for High Performance HVAC Applications
Vaisala Instruments

HMW92/HMW93/HMW95 Humidity and Temperature Transmitter

for High Performance HVAC applications

HMW92 amd HMW93 RH + T Transmitters

The 2-wire HMW92 ND HMW93 transmitters are designed for use in high performance HVAC applications such as museums, laboratories, data centers, and production facilities. The transmitter is quick and easy to install and use on the field even without any special tools. The most common settings, such as metric/non-metric and relative humidity / dew point unit selections, can be easily changed with dip switches when the enclosure is open.

On-site calibration and adjustment is exceptionally easy. The sliding cover lid exposes offset trimmers for 1-point calibration of both humidity and temperature parameters. The included display makes adjustment clear and convenient by instantly indicating the effects of any changes. A service port enables 2-point calibration, using either a PC or the Vaisala HUMICAP® Hand-Held Humidity and Temperature Meter HM70.

The transmitter also features a user exchangeable humidity and temperature module, which can be ordered as a spare part. The module is delivered with a calibration certificate.

Analog outputs are preset at the factory to:  




  • Channel 1: 4 ... 20 mA = 0 ... 100% RH
  • Channel 2: 4 ... 20 mA = -5...+55°C (-23...+131°F) T
  • Channel 1: 0...10 V = -5...+55°C (-23...+131°F) T
  • Channel 2: 0…10 V = 0...100% RH
  • Display: metric units
  • Relay set-point for relative humidity: not set
  • RS-485, BACnet MS/TP and Modbus RTU
