Johnson Controls DPT2640-0R5B Pressure Transducer

The Johnson Controls DPT2640-0R5B is a high-precision differential pressure transmitter designed for critical HVAC and building automation applications. Built for technicians who demand high-accuracy sensing in low-pressure environments, this low pressure transducer features a bi-directional input range of -0.5 to 0.5 inches Water Column (wc). It provides a linear 0-5 VDC output, making it compatible with various building management systems (BMS) and HVAC control sensors. This unit is engineered to withstand an operating temperature range from 0 to 175°F, ensuring stable performance in mechanical rooms and plenum spaces. With a 0.5% accuracy rating, the DPT2640-0R5B is ideal for static pressure monitoring, filter status indication, and air velocity measurements where precision is non-negotiable. Its robust design allows for direct conduit mounting, simplifying the installation process for contractors while providing reliable differential pressure sensing for long-term system optimization.

• High Precision Sensing: Delivers 0.5% accuracy for tight control in low differential pressure environments.
• Versatile Output: Standard 0-5 VDC output provides seamless integration with most bi-directional pressure controllers.
• Wide Operating Range: Performs reliably across a temperature spectrum of 0 to 175°F.
• Ease of Installation: Compact design supports direct conduit mounting for efficient field wiring.

• What is the primary application for the DPT2640-0R5B? This transducer is typically used for monitoring building static pressure, cleanroom air pressure, and high-efficiency filter loading.
• Does this unit support bi-directional pressure sensing? Yes, the -0.5 to 0.5 in. wc range allows for sensing both positive and negative differential pressures.
• Is calibration required upon installation? While factory-calibrated for high accuracy, technicians should perform a zero-point check within the controller during commissioning.
