Product Description

The SUP-P300 series is a compact diffused-silicon pressure transmitter for industrial gauge, absolute and sealed-reference pressure measurement. It adopts 316L stainless-steel isolating diaphragm, delivering high stability up to ±0.2%FS-0.5%FS accuracy and long-term stability of ±0.2%FS per year. Multiple output options include 4-20 mA, voltage signals and Modbus-RTU RS485 communication.

This transmitter supports diverse electrical connections: Hirschmann connector, aviation plug and direct cable outlet. Optional local LCD/LED display, high-temperature heat-dissipation fins are available for high-temperature media. Its measuring range covers -100 kPa to 60 MPa, with IP65-IP68 protection grade. Widely used in petroleum, chemical, water-treatment and power-plant sites for liquid and gas pressure monitoring.
