CHAPTER 2
PRODUCT OVERVIEW
This chapter introduces the features and options of the HMDW80 series
transmitters.
Introduction to HMDW80 Series
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.
HMDW80 series includes transmitters for wall and duct mounting,
humid areas, and for outdoor installation. It also includes temperatureonly transmitters and transmitters with an optional display. Calculated
humidity parameters – dewpoint, wet bulb temperature, and enthalpy –
are also available.
HMDW80 series transmitters require minimal maintenance thanks to
their excellent sensor stability and high-quality materials. If necessary,
the INTERCAP® humidity sensor can be easily exchanged in the field
with practically no downtime.
Features provided by transmitters in the HMDW80 series:
- ±3.0 %RH accuracy.
- 0 ... 100 %RH measurement range.
- User exchangeable INTERCAP® humidity sensor for easy field
replacement.
- Several output parameters; see section HMDW80 Series Transmitter
Models on page 10 for list of supported parameters by transmitter
model.
- Several IP65-classified models for demanding HVAC applications.
- UL-V0 flammability rating.
