DISCONTINUED ITEM-Replacement Model: Vaisala HMDW80 Series Humidity and Temperature Transmitters
The duct mounted Vaisala INTERCAP® Humidity and Temperature Transmitters HMD42 and HMD53 are designed for building automation applications. They combine reliable operation with excellent stability, providing low cost of ownership to the user.
The HMD42/53 transmitters measure humidity with a ±3 %RH accuracy and temperature with a ±0.4 °C (±0.72 °F) accuracy. They feature various selectable analog output signals and they can be powered by either AC or DC voltage.
The HMD42/53 humidity transmitters use Vaisala INTERCAP® Sensor - the interchangeable capacitive humidity sensor. The transmitters require no recalibration if the sensor is changed. This means great savings in overall maintenance costs.
The duct mount HMD42/53 transmitters can be installed in various measurement environments due to the robust IP65 (NEMA4) rated metal enclosure, which protects the sensor from dust and splashes of water. The wide measurement temperature range from -20 °C to +60 °C (-4 ... +140 °F) covers most HVAC applications.
