MAMAC Systems PR-274-R1-MA Low Pressure Sensor 4-20mA 2-Wire Output 12-40 VDC

The MAMAC Systems PR-274-R1-MA Enclosed Low-Pressure Transmitter with 4-20mA Output is a sensing part designed to measure low air pressure differences and convert them into an electrical signal for monitoring and control applications. Its solid-state capacitive sensor detect pressure variations between connected ports and produces a proportional current output based on the measured value. Applied in HVAC systems such as air handling equipment, ventilation units, and duct monitoring setups, the transmitter is mounted on a suitable surface and connected to pressure tubing and control wiring. Accurate pressure feedback enables the ability to regulate airflow conditions, monitor system operation, and the with a support effective control of air distribution processes.
