Product Overview

PT683D Dual Remote Seal Differential Pressure Transmitter is designed for demanding industrial processes requiring reliable differential pressure measurement with dual remote diaphragm seals.

The pressure on both process connections is transmitted through welded diaphragm seals and capillary tubes to the sensing element, preventing direct contact between the sensor and aggressive process media. This design provides excellent performance in high-temperature, corrosive, viscous or crystallizing applications while maintaining long-term measurement stability.

With intelligent electronics and HART communication, the PT683D is widely used for differential pressure, liquid level, density and flow measurement in industrial process control systems.
