Johnson Controls DPT2091-50G Differential Pressure Transducer 0-50 PSI 4-20mA

The Johnson Controls DPT2091-50G is a differential pressure transducer which measures the difference in pressure from two different reference points in an HVAC system. It functions by transforming the pressure differential into an equivalent electrical signal (4-20mA) that is easy to read by building automation systems. This makes it possible to achieve accurate control of different HVAC equipment. Made of rugged stainless steel, the is built to withstand harsh environments and features a wide operating temperature range -20°C to 85°C. It is used in Variable Air Volume (VAV) systems, fan filter units, pressure-independent control systems, and so on. They help to measure pressure differentials, control airflow, ventilate properly and manage the working of HVAC equipment.
