PMD55 PMD70 PMD75 Intelligent Pressure Transmitter / Digital Differential Pressure Transducer

PMD55- PMD70- PMD75 Series Intelligent Pressure Differential Pressure Transmitter

The PMD75 differential pressure transmitter adopts a pressure resistance sensor and a welded metal diaphragm, mainly used for differential pressure measurement of liquids, vapors, and gases in process or environmental industries. The measurement range can be adjusted, quickly set, simplify the debugging process, reduce costs, and save time. Compliant with IEC61508/IEC61511 standards and SIL3 safety requirements. Used for liquid level, volume or mass measurement, differential pressure monitoring of filters and pumps, and combined with pressure measuring components to measure gas, steam and liquid flow rates (volume or mass flow rates)

Modular digital transmitter with metal measuring diaphragm for long-term stability, high static pressure/overload resistance, enhanced safety secondary process barrier through self diagnostic function.

1. Optimal accuracy, reproducibility, and long-term stability;
2. The airtight feedthrough certified by IEC 61508 has the highest SIL2/3 capability and the highest safety;
3. Simple menu guided debugging through local display, 4 to 20mA, with HART PROFIBUS PA, Foundation fieldbus;

4. HistoROM data management concept enables quick and easy debugging, maintenance, and diagnosis. 5. Modular concept saves costs and facilitates the replacement of sensors, displays, or electronic devices
6. The overload resistance can reach up to 420bar/42MPa/6300psi, and the function is monitored
7. Seamless and independent system integration (HART/PA/FF)
