Duct Mount Relative Humidity Sensor Installation in HVAC System

The AcuHUM DM duct mount sensor measures accurate relative humidity and temperature within HVAC ductwork in building automation systems. By measuring air conditions directly within the duct, it provides reliable input for ventilation, heating, and cooling control, supporting accurate HVAC operation, indoor air quality, and occupant comfort.

Utilizing digital polymer sensing technology, the AcuHUM DM delivers fast response, low drift, and ±2% RH accuracy, ensuring stable humidity measurement under dynamic airflow conditions.

The sensor offers streamlined installation and system integration, with mounting and wiring features that reduce installation time while maintaining measurement accuracy for HVAC and BAS control.

Efficient Installation in HVAC Ductwork

The AcuHUM DM is built to simplify installation across a wide range of duct mounted HVAC applications. It can be configured with industry-standard thermistor, RTD, or transmitter output options, allowing both humidity and temperature measurement within a single device and reducing the need for multiple sensors.

Its design supports accurate installation in duct environments. An adjustable mounting flange allows the probe depth to be set during installation, ensuring the sensing element is positioned in well-mixed airflow for reliable measurements without repositioning.

Wiring is streamlined for efficiency. Push-button terminal blocks reduce wiring time, while quick-release, self-capturing cover screws provide fast access to internal terminals during installation and maintenance.

The IP65 rated enclosure protects the sensor from dust and moisture, allowing direct installation in HVAC duct systems without additional protection.
