MAMAC Systems PR-243-R3-VDC Pressure Sensor

The MAMAC Systems PR-243-R3-VDC is a professional-grade pneumatic pressure sensor engineered for precise monitoring in building automation and HVAC industrial control systems. This transducer utilizes a high-stability piezoresistive silicon sensing element to deliver a linear analog output based on gauge pressure. Designed specifically for the 3-15 PSIG pressure range, it is the standard choice for interfacing pneumatic systems with electronic controllers. The unit features field selectable output options of 0-5 VDC or 0-10 VDC, allowing for seamless integration with a variety of BAS hardware. Its robust NEMA 4 (IP-65) enclosure provides protection against environmental contaminants, ensuring long-term reliability in mechanical rooms. With a wide supply voltage range of 12-40 VDC or 12-35 VAC, this low-pressure transducer offers the flexibility required for diverse field installations. The NIST traceable calibration ensures high accuracy, while the unpluggable screw terminal block simplifies the wiring process for technicians in the field.

• Selectable Voltage Output: Configure for 0-5V or 0-10V signals via onboard dip switches to match your controller’s input requirements.
• Industrial Durability: The 18-gauge cold-rolled steel NEMA 4 enclosure protects sensitive electronics from moisture and dust.
• Precision Sensing: Employs a 100% solid-state silicon chip for minimal hysteresis and excellent repeatability across the 3-15 psi range.
• Flexible Powering: Compatible with both AC and DC supply voltages (12-40VDC/12-35VAC), eliminating the need for dedicated power converters.
• Ease of Maintenance: Includes an unpluggable terminal block and accessible zero/span trimmers for efficient field calibration and servicing.

Common Questions

What media is compatible with the MAMAC PR-243-R3-VDC?
This sensor is designed for use with clean, dry air or non-corrosive inert gases. It should not be used with liquids, oxygen service, or in hazardous/explosive environments.

How do I change the output signal from 0-5V to 0-10V?
The output is field selectable. You can adjust the signal range by setting the internal dip switches according to the technical schematic provided in the installation manual.

Can this unit be mounted in any orientation?
For optimal performance and to maintain the NEMA 4 rating, the unit should be mounted on a vertical surface with the 1/4" brass hose barb pointing either left or right.
