MAMAC Systems PR-276-R10-MA Sensor

The MAMAC Systems PR-276-R10-MA is a professional-grade duct pressure sensor designed for rigorous static pressure monitoring within commercial and industrial building automation systems. Built with a solid-state, glass-on-silicon capacitive sensing element, this unit provides precise measurements of differential pressure in dry air or inert gas environments. It features field-selectable ranges of 0-5" WC, 0-2.5" WC, and 0-1.25" WC, allowing technicians to calibrate the device to specific HVAC duct pressure requirements on-site. The 4-20mA 2-wire current loop output ensures signal integrity over long cable runs, while the 12-40 VDC supply voltage compatibility integrates seamlessly with standard BAS controllers. Housed in a rugged NEMA 4 (IP66) weatherproof metal enclosure, the PR-276-R10-MA is engineered to withstand demanding mechanical room conditions while maintaining ±1% full-scale accuracy. This model includes an integrated static pressure probe, simplifying installation by eliminating the need for separate pickup tubes.

Key Benefits

• Field-Selectable Versatility: Multiple pressure ranges and uni/bi-directional modes allow a single SKU to cover various static pressure sensor applications.
• Industrial-Grade Durability: The NEMA 4 enclosure protects internal electronics from moisture, dust, and mechanical impact.
• High Signal Stability: Advanced capacitive sensing technology reduces drift and environmental interference for long-term reliability.
• Simplified Installation: 4-20mA 2-wire configuration reduces wiring costs and includes built-in reverse polarity and short-circuit protection.
• Precision Performance: Integrated zero and span adjustments enable highly accurate field calibration to match specific air pressure transducer requirements.

Common Questions

What media is compatible with the PR-276-R10-MA?
This sensor is designed for use with inert, dry air or non-corrosive gases. It should not be used with liquids or in applications with high moisture content that could condense on the silicon sensor.

Can I change the pressure range after the unit is installed?
Yes, the MAMAC Systems PR-276 series features internal dip switches that allow a technician to select between the three scales (5", 2.5", and 1.25" WC) without needing to replace the hardware.

What happens if the pressure exceeds the rated range?
The unit features overpressure protection with a proof pressure of 15" WC and a burst pressure of 23" WC, providing a safety margin against sudden duct pressure spikes.
