Introduction

The STJE is one of the most accurate pressure sensors on the market today. The accuracy is 0.05%, and the zero to temperature sensitivity is less than 0.003% PE / °C. The construction is based on a fully welded double jacket. The pressure ranges are from 70 mbar to 520 bar.

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 STJE is offered in 2 versions:

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