Pressure transmitter / Pressure switch with data memory

Precont PN4SC

Pressure transmitter and switch for industrial pressure monitoring from 0…50 mbar to 0…60 bar, with 0/4…20 mA or 0…10 V output, up to 4 PNP switching outputs, color display and data logger for over 500,000 values.
Product Inquiry

Introduction

This transmitter and pressure switch covers finely graduated ranges from 0…50 mbar to 0…60 bar and supports relative or absolute pressure versions, making it adaptable across hydraulic, pneumatic, HVAC, refrigeration, environmental technology and building automation tasks.
 
High measurement confidence comes from accuracy options down to ≤ ±0.05% of the measuring range with Xcellence linearity protocol. The graphic color display, keypad and rotatable housing support convenient operation in almost any mounting position, while the integrated data logger stores over 500,000 measured values for process analysis and documentation.
 
For demanding environments, the device combines a ceramic Al2O3 sensor with ingress protection (IP65/IP67), 15g shock resistance and 4g vibration resistance. Flush process connection options support CIP/SIP cleaning processes where cleanability of wetted surfaces matters.

Features

Pressure measurement principle

The device uses a capacitive ceramic Al2O3 sensor with either an internal or flush process membrane, depending on the selected process connection.

Analog output

The electronics provide a configurable current output 0/4…20 mA or voltage output 0…10 V for connection to control and monitoring systems.

Switching outputs

Output versions are available with 2 or 4 PNP switching outputs. Each PNP output is current-limited, short-circuit-proof and rated up to ≤ 200 mA.

Data logger function

The integrated measurement data memory records over 500,000 measured values. A version with timestamp and support battery is available.

Process connections

The product family includes ISO 228-1, ANSI NPT, DIN 11851, Varivent, DRD and Clamp process connection options, including flush versions.

Process temperature versions

Versions are available for -40°C…+100°C and -40°C…+125°C, with temperature decoupler for the higher process temperature range.

Electrical connection

The device uses an M12-A connector, with 4-pin, 5-pin or 8-pin versions according to the selected output configuration.
