Humidity and Temperature Transmitter Series for use in energy management systems in buildings.


Vaisala INTERCAP® Humidity and Temperature Transmitter Series HMDW80 measure relative humidity and temperature in various building automation applications.
Transmitters combine easy installation and reliable operation with a low requirement for maintenance.
The versatile HMDW80 series includes transmitters for wall and duct mounting, IP65-classified transmitters for humid areas, and transmitters with a radiation shield for outdoor use.
It also includes temperature-only transmitters and transmitters with an optional display.
Calculated humidity parameters – dew point temperature, wet bulb temperature, and enthalpy – are also available.

Easy Installation

HMDW80 series transmitters are optimized for easy installation.
There are no loose parts, screws are retained in the enclosure, all connectors are clearly labeled, and the connectors are within easy reach.
The duct mount transmitters are well suited to a variety of duct sizes, the outdoor transmitters can be mounted directly onto a wall or pole without any extra accessories, and the wall mount transmitters can be installed without the need to make holes in the transmitter enclosure.

Reliable Operation
HMDW80 series transmitters require minimal maintenance thanks to their excellent sensor stability and high-quality materials.
