The wall-mounted Vaisala HMW90 Series HUMICAP® Humidity and Temperature Transmitters measure relative humidity and temperature in indoor environments, where high accuracy, stability, and reliable operation are required.
The HMW90 series includes models for both current and voltage output. These flexible transmitters offer a variety of options and features.
Transmitters include a display and a sliding cover with either a display opening or a solid front. Output options include both special scalings and calculated dew point and mixing ratio parameters.
The HMW90 series transmitters are quick and easy to install. The wiring is connected through the back plate and the electronics with the sensors can then be easily snapped on after wiring is completed.
Dip switches for transmitter configuration can be accessed when the enclosure is open. The most common settings, such as metric/ non-metric unit selection and relay set-point, can be easily changed without special tools.
