MAMAC Systems PR-275-R3-VDC Pressure Sensor 318423-701 Contractors should cross-reference the S1-373-20055-004

Contractors should cross-reference the S1-373-20055-004 part number with the machine's data plate to confirm exact compatibility

Reliable Fail-Safe: The LF24-SR S/R actuator ensures positive closure during power loss to prevent coil freezing or uncontrolled infiltration

The Aaon R05040 detects these issues to protect the compressor from running in a vacuum

Rugged Reliability: Engineered with high-grade materials to withstand the thermal and electrical fluctuations typical in industrial HVACR environments

Engineered for damper control and butterfly valve automation

MAMAC Systems PR-275-R3-VDC Pressure Sensor 318423-701 Contractors should cross-reference the S1-373-20055-004For high precision air pressure monitoring, the MAMAC Systems PR 275 R3 VDC is a versatile low pressure sensor engineered with glass on silicon (Gl Si) capacitance technology. This veteran grade differential pressure transducer provides superior stability by addressing common field issues like zero drift and calibration shift. It offers six field selectable pressure rangesincluding 0 5"wc, 0 2. 5"wc, 0 1. 25"wc, and compound ranges like 2. 5" to 2.
