Keunggulan Teknis Kritis
-
Extreme Temperature and Pressure Range: The PMP75 is built for the “extremes,” managing pressures up to 400 bar and temperatures up to 400°C. The diaphragm seal system prevents the process medium from directly contacting the sensor, protecting the instrument while maintaining an accuracy of ±0.075%.
-
TempC Membrane Technology: This transmitter can be equipped with the TempC Membrane, which significantly reduces measurement drift caused by fluctuating ambient or process temperatures. It ensures much higher precision and faster recovery times in applications where temperature instability is common.
-
Maximum Safety (SIL 2/3): Certified for use in high-integrity safety loops, the PMP75 features a gastight feedthrough. This secondary containment ensures that process media cannot escape into the electronics or the environment, even in the event of a primary seal failure.
-
HistoROM Data Management: The HistoROM module stores all device parameters, allowing for rapid commissioning and “plug-and-play” replacement of components. If a module is swapped, the configuration is automatically restored, minimizing downtime and human error.
-
Advanced Diagnostics: The device features continuous function monitoring from the measuring cell through to the electronics. It is also overload-resistant, ensuring it maintains its calibration even after significant pressure spikes.
-
Dual-Chamber Housing: The separate compartments for wiring and electronics provide superior protection against moisture ingress and atmospheric corrosion during installation and maintenance.
