Description
The Johnson Controls DPT2641-0R1D Differential Pressure Transducer is an instrument that measures small changes in pressure in the HVAC systems. It operates through the measurement of the pressure differential between two locations in a duct and produces an electrical signal of 4-20 mA. This signal is then fed to an automation system for monitoring and control of the system and its components. It is suitable for use in measuring low-pressure differentials across filters, coils, and dampers, among others. When pressure drops are measured correctly, the technicians can maintain efficient airflow across the entire HVAC system.
