PT-407 Pressure Transmitter | Industrial Mini Hirschmann Pressure Sensor for HVAC/R

Product Overview：

1，Engineered for demanding HVAC/R and industrial cooling applications, the PT-407 Pressure Transmitter offers a rugged and highly reliable pressure measurement solution. Built with a world-class silicon piezoresistive sensing element and high-integration signal processing circuitry, the PT-407 utilizes advanced digital temperature compensation and non-linear correction to produce linear analog outputs (4–20mA, 0–5VDC).

2，To overcome moisture-induced failures in thermal cycling environments, the PT-407 features an advanced anti-condensation design that seals sensitive electronics against humidity and internal dew formation. Equipped with a standard mini Hirschmann GDS-307 connector, it ensures secure electrical connection and quick field installation, making it perfect for screw chillers, commercial freezers, and refrigeration systems.

Key Features & Highlights：

1，Standard Mini Hirschmann GDS-307 Plug: Features an industry-grade mini Hirschmann connector for excellent ingress protection, secure wiring, and effortless installation/maintenance.

2，Advanced Moisture & Dew Protection: Specialized cavity sealing prevents water vapor condensation, guarding electronics against humidity damage during extreme temperature drops.

3，Full-Range Digital Calibration: Precise digital temperature compensation mitigates thermal drift, maintaining exceptional accuracy, sensitivity, and linearity across all operating conditions.

4，High-Integration Signal Conditioning: Driven by a specialized bridge sensor signal processor, ensuring strong anti-interference performance and superior long-term zero-point stability.

Target Applications：

1，Water-cooled screw chillers & centrifugal chillers

2，Commercial freezing tunnels & cold room refrigeration

3，Central air conditioning pressure management

4，Heat pumps and refrigerant recovery units
