Description
The MAMAC Systems PR-274-R2-MA Low Pressure Transducer is a pressure sensing instrument used to measure differential air or gas pressure and convert it into a 4–20 mA output signal for monitoring and control within HVAC systems. It operates through a capacitive sensing element that detects pressure changes and produces a proportional electrical signal based on system conditions. The output is sent to controllers or building automation systems for pressure supervision. Installed in air handling units, duct networks, and filter monitoring applications, connected to sensing tubes and control wiring during setup for continuous measurement and stable operation.
