Emerson

1.Main Functions

• Gauge pressure measurement: Measures process pressure relative to ambient atmospheric pressure, using piezoresistive sensing diaphragm.www.plcva.com
• Signal conversion: Converts physical pressure value into standard 4–20 mA analog loop signal superimposed with HART digital signal.
• HART smart communication: Supports remote configuration, parameter adjustment, zero / span calibration, and device diagnosis via HART protocol.
• Local LCD display: Shows real-time pressure reading, engineering units and device status on site.
• Built-in self-diagnosis: Continuously monitors sensor, electronics and loop faults; outputs defined alarm levels upon failure.
• Overpressure protection: Tolerates high overpressure without permanent sensor damage.
• SIL-certified safety capability: Suitable for Safety Instrumented Systems (SIS) for process safety interlock.
• Temperature compensation: Automatic thermal compensation to minimize measurement drift under varying process temperature.

Core summary: It senses the gauge pressure of liquid or gas media, converts pressure into standard 4–20mA+HART signal, transmits measurement data to PLC/DCS for real-time process monitoring and closed-loop control.plcva.com
