HMDW80 Series Humidity and

Temperature Transmitters

For building automation applications

Features

• Reliable transmitters for basic

HVAC humidity measurements

• ±3.0 %RH accuracy

• Full 0 … 100 %RH measurement

range

• Optimized for easy installation

and low maintenance

• User exchangeable INTERCAPâ

sensor for easy field replacement

humidity and temperature with

optional dew point temperature,

wet bulb temperature and

enthalpy parameters

Vaisala HMDW80 Series INTERCAPâ Humidity and Temperature Transmitters measure

relative humidity and temperature in various building automation applications.

HMDW80 series transmitters combine easy installation and reliable operation with a

low requirement for maintenance.

Typical installation locations

• Ventilation ducts

• Walls

• Wash-down areas

• Outdoor locations

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. If necessary, the

INTERCAPâ sensor can be easily

exchanged in the field with minimum

downtime.
