The PS-500B Differential Pressure Sensor is a high-precision, industrial-grade differential pressure sensor engineered for critical process monitoring and control in regulated environments. Designed with dual stainless steel ports and a robust ceramic sensing element, it delivers exceptional long-term stability and repeatability. With a full-scale range of ±5 kPa, the PS-500B is ideal for low-differential applications including cleanroom pressure cascades, HVAC filter monitoring, medical gas delivery systems, and biopharmaceutical process validation—where accuracy, traceability, and compliance are non-negotiable.
This sensor features native RS485 pressure sensor communication using the widely adopted Modbus RTU protocol (ASCII optional), enabling seamless integration into SCADA, DCS, and IIoT platforms without additional signal conditioning. Each unit ships with individual NIST-traceable calibration documentation—certified to ±0.25% FS accuracy—and meets FDA-compliant materials and surface finish requirements for use in pharmaceutical, food & beverage, and life sciences facilities.
