MAMAC Systems PR-264-R1-MA Pressure Sensor

The MAMAC Systems PR-264-R1-MA is a high-accuracy differential pressure transducer engineered for reliable performance in demanding HVACR and industrial automation environments. This rugged wet-to-wet pressure sensor features a 316L stainless steel sensing element, making it compatible with any gas or liquid that is non-corrosive to that alloy. Designed for versatility, the PR-264-R1-MA offers field selectable pressure ranges of 0-25, 0-50, and 0-100 PSIG, allowing technicians to calibrate the unit on-site to match specific application requirements. It operates on a 12-40Vdc supply and provides a standard 4-20mA output, ensuring seamless integration with most building automation systems (BAS) and industrial controllers. With its NEMA 4 (IP65) rated enclosure, this 0-100 PSIG pressure sensor is built to withstand harsh conditions while maintaining high stability and minimal thermal drift. For contractors managing complex liquid lines or pump monitoring, this sensor provides the precision necessary for critical pressure monitoring solutions.

• Field Adjustable Versatility: Three selectable ranges (25, 50, 100 PSIG) reduce the need to carry multiple SKUs on the service truck.
• Robust Construction: Utilizing 316L stainless steel prevents corrosion issues when monitoring water, oil, or compatible gases.
• High Overpressure Protection: Built to handle surges without catastrophic failure, maintaining system reliability in high-flow environments.
• NEMA 4 Enclosure: Provides a moisture-tight seal for installations in mechanical rooms or outdoor locations.
• Simplified Wiring: A standard 2-wire 4-20mA current loop reduces installation time and minimizes potential wiring errors during HVAC sensor installation.

How do you calibrate the output for different ranges?
The PR-264 series features internal dip switches that allow you to toggle between the 25, 50, and 100 PSIG settings without requiring specialized factory recalibration tools.

Is the PR-264-R1-MA compatible with refrigerant lines?
This sensor is compatible with any media that does not react with 316L stainless steel; however, always verify the specific lubricant and refrigerant compatibility against the alloy's chemical resistance properties.

What is the maximum supply voltage for this unit?
The sensors are designed to operate efficiently on a DC power supply ranging from 12Vdc to a maximum of 40Vdc.
