Pressure transmitter for industrial pressure monitoring

Precont PU4SK

Pressure transmitter for industrial pressure monitoring in gases, vapors, liquids and dusts, with ranges from 250 mbar to 600 bar, 4…20 mA FSK, RS485 Modbus®-RTU, IO-Link® or 0...10 V output and IP69K/IP67 housing.

Introduction

In machine building, process equipment and environmental technology, pressure measurement has to stay stable across changing media, high loads and demanding cleaning routines. This pressure transmitter monitors, controls and continuously measures pressure in gases, vapors, liquids and dusts, with measuring ranges from 250 mbar to 600 bar and accuracy up to ≤ ±0.15% FSO.
 
The wide choice of process connections and electronics makes it adaptable to many industrial tasks, including hydraulic and pneumatic systems, HVAC and refrigeration, building automation and process industry applications. Output options include 4…20 mA FSK, RS485 Modbus®-RTU, IO-Link® and 0...10 V.
 
A robust fully welded stainless steel housing with ingress protection (IP69K/IP67) supports use in harsh environments. The ceramic Al2O3 96% strain-gauge measuring cell is long-term stable, while flush-mounted versions support process-integrated cleaning of the wetted diaphragm, including CIP/SIP processes.
