Description
The MAMAC Systems PR-275-R3-VDC is a versatile, field-configurable low differential pressure sensor engineered for demanding building automation and HVAC control applications. Designed to deliver precise, reliable pressure measurement across a wide variety of system types, this sensor eliminates the need for multiple SKUs by offering six field-selectable pressure ranges and dual output options — all in a single, compact unit.
Field-Selectable Pressure Ranges
- 0 to 5″ w.c.
- 0 to 2.5″ w.c.
- 0 to 1.25″ w.c.
- -2.5″ w.c. to +2.5″ w.c. (bidirectional)
- -1.25″ w.c. to +1.25″ w.c. (bidirectional)
- -0.625″ w.c. to +0.625″ w.c. (bidirectional)
Field-Selectable Output Signal
- 0–5 Vdc
- 0–10 Vdc
Power Supply
- 12–40 Vdc
- 12–35 Vac
Key Features & Benefits
- Six field-selectable pressure ranges reduce inventory requirements and simplify commissioning
- Dual VDC output options (0–5V or 0–10V) for compatibility with a wide range of BAS and DDC controllers
- Wide supply voltage range (12–40 Vdc / 12–35 Vac) for flexible installation across various power sources
- Bidirectional range options support both positive and negative pressure measurement
- Compact, rugged housing suitable for duct, room, or equipment room mounting
- Ideal for monitoring air pressure in ducts, air handlers, clean rooms, and VAV systems
Typical Applications
- Variable air volume (VAV) duct static pressure control
- Air handler unit (AHU) differential pressure monitoring
- Filter status and pressure drop monitoring
- Clean room and laboratory pressure differential measurement
- Building automation system (BAS) integration
The MAMAC PR-275-R3-VDC is the smart choice for contractors and controls technicians who need one sensor that can adapt to virtually any low-pressure application on the job site.
