MAMAC Systems PR-264-R2-VDC Pressure Sensor

The MAMAC Systems PR-264-R2-VDC Pressure Sensor is a high-performance HVAC pressure transmitter designed for demanding commercial and industrial applications. This unit features a 100% solid-state fused silicon pressure sensor and a 316L stainless steel monolithic cavity, making it highly resistant to leaks and vibrations. With field-selectable pressure ranges of 0-300 PSIG, 0-150 PSIG, and 0-75 PSIG, this single industrial pressure sensor can replace multiple fixed-range items in your truck, reducing inventory costs. The output signal is equally versatile, offering field-selectable 0-5Vdc or 0-10Vdc configurations to match any controller input. Encased in a rugged NEMA 4 (IP-65) enclosure, it is purpose-built to withstand moisture and harsh mechanical rooms. For reliable 0-10V pressure sensor performance, this unit supports a wide supply voltage range from 12-40Vdc, ensuring stable readings even with unregulated power sources.

• Field-Selectable Flexibility: Easily configure ranges (75/150/300 PSIG) and outputs (0-5/0-10Vdc) via internal dip switches to meet specific job requirements.
• Rugged Construction: The 316L stainless steel wetted parts and monolithic cavity design eliminate welds and O-rings, ensuring long-term leak protection.
• Advanced Protection: Features short circuit and reverse polarity protection to prevent damage during field wiring and commissioning.
• NIST Traceable Accuracy: Delivers +/- 1% FS accuracy for precise HVAC automation and process control.
• Simple Installation: Includes an unpluggable terminal block and a 1/8" NPT process connection for rapid mounting and maintenance.

Can this sensor be used with liquid and gas media?
Yes, the 316L stainless steel construction is compatible with any media that is non-corrosive to 316L SS, including water, glycol, and various gases.

Does the PR-264 require a regulated power supply?
No, the unit handles a wide unregulated supply voltage of 12-40Vdc (or 12-35Vac for VDC units), allowing for stable operation with standard 24V control transformers.

How do I calibrate the zero and span in the field?
The circuit board is equipped with easily accessible zero and span trimmers (Z/S) for fine-tuning the calibration after installation.
