High-Flow Capacity: Optimized internal geometry supports maximum flow rates with minimal pressure drop for 3/4 inch gas lines

providing the robust performance required for high-tonnage heat pumps and air handlers

The output signal is linearly proportional to the input pressure

The robust construction and corrosion-resistant materials make it highly resilient

Introducing liquids or corrosive gases will cause permanent damage to the stainless steel sensor components

Belimo 22DTH-51ML Sensor 321702-401 High-Flow Capacity: Optimized internal geometryThe Belimo 22DTH 51ML is a high precision duct sensor engineered for demanding HVACR environments that require integrated humidity and temperature monitoring. This unit features a selectable 0 5V or 0 10V active output for humidity, alongside a passive NTC10k2 (10k type 2) thermistor for accurate temperature feedback. Built with a polymer capacitive sensor and a stainless steel wire mesh filter, it ensures long term stability and resistance to
