Accuenergy AcuHUM-DM-A-A-02 Offers

The AcuHUM DM series duct mount relative humidity (RH) sensor utilizes advanced digital polymer sensing technology for high-precision RH measurement, long-term stability, and fast response time. Ideal for HVAC systems, the AcuHUM DM is tightly sealed in an IP65-rated enclosure and includes a PE polymer filter providing protection against dust, condensation & particulates. The RH sensor is secured with a 4-screw mounting flange with a set screw, enabling adjustable probe depth. The AcuHUM DM provides thermistor, RTD, and transmitter options, enabling temperature and RH readings in one device.

A duct mount relative humidity and temperature sensor is a digital polymer device designed to provide accurate and stable humidity/temperature readings in the duct system. Commonly used in HVAC infrastructures to deliver real-time data for building automation systems to adjust the heating, cooling, humidity levels and ventilation based on environmental conditions.

Applications

Monitors HVAC/R Air Condition

Engineered to be easily integrated into duct networks, AcuHUM DM features a built-in probe with adjustable depth, an IP65 enclosure, and a PE polymer filter for protection against dust/debris. The RH/temperature sensor accurately monitors the humidity and temperature levels of the air flowing through the ducts, making sure the HVAC system operates at the optimal condition.

Support Economizer Function

Measures the temperature and humidity of the return air, AcuHUM DM allows BAS controllers to compare the conditions between indoor and outdoor environments to automate the internal circulation of outdoor air for more efficient cooling, and to minimize energy consumption while ensuring optimal indoor environmental conditions.

Humidification and Dehumidification

AcuHUM DM monitors the RH level of the supply and return air in real-time, delivering accurate readings to the air handling unit (AHU) to adjust accordingly. If the humidity level is out of the optimal range, typically beyond 30% to 60% RH, the system will automatically trigger humidification or dehumidification functions to ensure a comfortable environment.
