BELIMO 22DTH-11M

In the demanding world of HVAC and building-automation systems, having dependable and versatile measurement devices is essential. The BELIMO 22DTH-11M rises to this challenge by combining humidity and temperature sensing in one unit that is designed specifically for duct-mount applications. Whether you need to monitor relative humidity (RH), absolute humidity (AH), dew point or enthalpy alongside air temperature, this sensor gives you the flexibility to switch modes and integrate seamlessly into your control strategy. With selectable 0–5 V or 0–10 V outputs, it easily interfaces with standard building automation systems without needing extra converters. The standard 140 mm probe length and 19.5 mm probe diameter (for the 11M version) are ideal for air-duct insertion, while the IP65/NEMA 4X enclosure ensures durability in dusty, humid, or industrial ventilation environments. It solves the problem of needing separate sensors for humidity and temperature by combining both in one compact unit—thereby reducing wiring, calibration, and maintenance complexity. Compared to simpler temperature-only or humidity-only sensors, the 22DTH-11M offers significantly greater functionality, delivering more data (humidity, temperature, dew point, enthalpy) from the same mounting point. For HVAC contractors, building-automation integrators and energy-management specialists, this means faster installation, fewer spare parts and stronger system performance.
