Belimo 22DTH-51M Sensor
The Belimo 22DTH-51M is a precision duct-mounted sensor engineered for simultaneous measurement of relative humidity and temperature in demanding HVAC systems. Designed for seamless integration with BMS controllers, this unit features selectable output signals of 0-5V or 0-10V, ensuring broad compatibility with diverse analog input requirements. This multi-sensor utilizes a high-accuracy capacitive polymer humidity element and a stable temperature sensing component to provide reliable environmental monitoring. Its NEMA 4X / IP65 rated enclosure provides superior protection against moisture and contaminants, making it suitable for both commercial and light industrial applications. Maintenance is simplified through a removable mounting flange and a tool-free housing design, allowing for efficient field installation and commissioning. Whether managing enthalpy control, economizer cycles, or indoor air quality (IAQ) monitoring, the 22DTH-51M delivers the signal stability and response time necessary for accurate climate control and energy efficiency.
Key Benefits- Dual-function sensing provides relative humidity and temperature data from a single duct penetration.
- Field-selectable 0-5/10V DC outputs allow for flexible configuration with various building automation systems.
- NEMA 4X / IP65 rated housing ensures long-term performance in high-moisture or dusty duct environments.
- Removable probe and mounting flange facilitate rapid installation and easier calibration checks.
- High-accuracy sensing elements minimize drift and reduce the need for frequent field offsets.
What is the accuracy rating for the humidity sensor?
The Belimo 22DTH-51M typically maintains an accuracy of +/- 2% RH in standard operating ranges, providing the precision needed for demand-controlled ventilation.
Can I change the output signal after installation?
Yes, the analog output signal is selectable via internal jumpers, allowing technicians to switch between 0-5V and 0-10V as required by the controller.
Is this sensor suitable for plenum-rated applications?
Yes, the materials and construction are designed to meet standard HVAC duct sensor requirements for air handling units and plenum spaces.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
