PT-504A Dual Temperature & Pressure Transmitter | IP68 Sealed 2-in-1 Sensor

Product Overview：

1，The PT-504A Pressure Transmitter is an advanced 2-in-1 integrated sensor engineered for comprehensive process control. By combining a high-precision pressure sensing element with a surface-mounted ceramic RTD temperature sensor, the PT-504A delivers simultaneous pressure and temperature measurements through a single process port, drastically reducing piping modifications and installation costs.

2，Built for harsh operating environments, the PT-504A features a full laser-welded housing with IP68 ingress protection, ensuring complete submersion capability and long-term durability. Driven by a specialized signal-conditioning IC with full-temperature digital calibration and reverse-polarity protection, it is the ideal choice for hydraulic systems, compressors, pumps, marine, and industrial HVAC/R applications.

Key Features & Highlights：

1，2-in-1 Temperature & Pressure Integration: Measures both fluid temperature and pressure simultaneously from one port, saving manifold space and simplifying field wiring.

2，Surface-Mounted Ceramic RTD: Features fast thermal conductivity for rapid response times and reliable temperature feedback.

3，IP68 Laser-Welded Sealing: Rugged, fully sealed stainless steel construction provides submersion-grade waterproof performance for high-humidity and outdoor environments.

4，High-Precision Signal Conditioning: Integrated bridge-sensor conditioning IC provides full-span temperature compensation, excellent anti-interference, and long-term zero stability.

5，Reverse-Polarity Protection: Built-in circuit protection guards 4–20mA loops against accidental reverse wiring damage during field setup.

6，Fully Customizable Options: Flexible choices for process threads (NPT, BSPP, M20x1.5), pressure/temperature ranges, and custom output configurations.

Applications：

1，Industrial Compressors & Pumps: Simultaneous monitoring of oil/fluid temperature and pressure.

2，Hydraulic Power Units (HPUs) & Heavy Machinery: Hydraulic fluid health and pressure management.

3，Refrigeration & HVAC/R Chillers: Dual parameter sensing for refrigerant lines.

4，Marine & Offshore Automation: Submersible and high-humidity process line measurement.
