Smart OEM RS485 Pressure Transducer Pressure Transmitter

From -100kPa to 60MPa in 12 standard range codes plus a customizable option, meeting the pressure measurement needs of most industrial applications.

Stainless steel diaphragm piezoresistive element is laser-trimmed at the factory to correct zero drift and temperature characteristics, delivering 0.5% FS default accuracy and optional 0.2% or 0.1% FS

Withstands instantaneous overpressure up to twice the rated range for measurements below 7 MPa, and 1.5 times for ranges at or above 7 MPa, protecting the sensor during pressure surge events.

Integrated circuit-level protection against reverse polarity wiring, instantaneous overcurrent, and overvoltage meets EMI requirements, reducing damage risk from wiring errors or power anomalies.

PM321 and PM354 high-temperature models handle process media up to 150 degrees C, while the standard variant covers -40 to 75 degrees C, covering steam, hot oil, and high-temp chemical processes.

PM350, PM351, PM353, and PM354 hygienic models feature clamp-type KG installation compatible with sanitary piping, meeting strict hygiene requirements in food processing and pharmaceutical.

Available Hirschmann connector option replaces bare-wire termination with a standardized plug-in interface, reducing wiring time and connector errors during installation.

Integrated keypad allows direct configuration of communication address, baud rate, zero range, and full-scale range on-site without connecting to a laptop or external configuration tool.

Six standard threaded connection options cover the most common industrial pipe fittings globally, eliminating the need for adapters in the majority of process pipe and manifold installations.

Every unit undergoes multi-point factory calibration with imported reference pressure sources across component, semi-finished, and finished product stages.
