Introduction

The pressure sensors model Z are fully welded stainless steel sensors designed for rugged industrial applications that require high accuracy and stability of measurement. Pressure ranges are from 35 mbar to 4000 bar. They use 350 ohm strain gauges mounted in a full bridge configuration.

Setup

Configuration options include:

Extended operating temperature range
Electrical connection
Amplified output (5 Vdc or 10 Vdc and 4 mA to 20 mA)

Most amplified models have internal shunt calibration circuits as a standard feature to facilitate sensor configuration on the acquisition system.

The model Z is offered in 2 variations:

"Gauge" version: the pressure measurement is made with the atmospheric pressure as reference. It allows to have an offset independent from the environment.
Absolute" version: the measurement is made with a fully welded vacuum cavity as reference, which increases the long term stability.
