Johnson Controls DP140005U21D Differential Pressure Transmitter 0-5" WC 4-20mA Accuracy 0.5%

The Johnson Controls DP140005U21D Differential Pressure Transmitter is used for accurate control of airflow and pressure in HVAC systems. It can work in a 0-5 inch water range and sends a 4-20mA signal with a 0.5 percent error to the control system to be regulated. It is a common usage in the air handling unit, duct systems and filtration assemblies used in residential and commercial buildings as a part of the monitoring system that can help regulate the balance of airflow. This operation of the system enables the HVAC systems to control the ventilation and stable pressure levels.
