Digital pressure sensor for gases and liquids up to 1000 bar

Precont S20

Digital pressure sensor for industrial pressure measurement in gases and liquids from -1...1000 bar, with metal membrane, bright 4-digit LED display, 4...20 mA or 0...10 V output and optional 2 PNP switch outputs.

Introduction

In demanding industrial pressure measurement, stable readings and rugged construction matter as much as the measuring range. Precont S20 measures gauge pressure, absolute pressure and vacuum in liquid and gaseous media from -1...1000 bar, giving engineers one sensor family for many pressure tasks across industrial measurement applications.
 
The metal membrane withstands pressure shocks up to 6 times the nominal pressure and offers vacuum resistance, good reproducibility, low hysteresis and strong long-term stability. Measuring accuracy is available down to ≤ ±0.15% FS, supporting dependable process insight where pressure values influence safety, quality or machine behavior.
 
Commissioning and daily use stay practical on site. A bright 4-digit LED display makes the current pressure easy to read from a distance, while the electronics can be rotated by 330° for better viewing and access. Depending on configuration, the sensor provides 4...20 mA 2-wire or 0...10 V 3-wire output, combined with up to 2 freely adjustable PNP switch outputs.

Features

Pressure measurement

Measures liquid and gaseous media and supports gauge pressure, absolute pressure and vacuum applications within the configured pressure range.

Metal membrane

Uses a metal measuring membrane with vacuum resistance, good reproducibility, low hysteresis and low temperature influence.

Output configurations

 Provides 4...20 mA 2-wire electronics or 0...10 V 3-wire electronics, with versions available with or without display.

Switching functions

Offers up to 2 freely adjustable PNP switch outputs. One switch output can be assigned as a fault signal output.

Display and operation

Includes a bright LED display for measured value indication and menu-based setting of switch points. A password function protects settings against changes.

Housing and connection

Available with stainless steel or PBT connection housing, terminal compartment or M12x1 connector, depending on configuration.

Process connections

Supports G½" and G¼" manometer connections as well as flush-mounted G½" and G1" process connections for suitable media.

Environmental protection

Housing versions provide ingress protection (IP65) or ingress protection (IP67) according to EN/IEC 60529.
