HMW90

Humidity and Temperature Transmitters for High Performance HVAC Applications

 

Wall-mounted Vaisala HMW90 Series HUMICAP® Humidity and Temperature Transmitters measure relative humidity and temperature in indoor HVAC applications, where high accuracy, stability, and reliable operation are required.
The flexible HMW90 series offers a variety of options and features.
Transmitters include a display and a sliding cover with either an opening for the display or a solid front.
Both analog and digital output options, including special scalings and calculated parameters, are available.

Quick and Easy to Install
HMW90 series transmitters are quick and easy to install.
The wiring is connected through the back plate and the electronics with the sensors can be snapped on easily after the wiring is complete.
The transmitter is configured using dip switches, which are accessible when the enclosure is open.

Digital Communication Brings Benefits
The introduction of digital (BACnet/ Modbus) communication to field level devices brings many advantages.
For example, all sensors can be centrally accessed and their performance can be easily monitored.
Wiring is simple when multiple sensors are installed on the same bus.
Sensors can be set up using standardized tools, and the system can be enlarged with additional sensors quickly and conveniently.
In addition, parameters influencing measurements, such as pressure or site elevation, can be centrally set and updated.
