Intrinsically Safe Pressure Sensor | ATEX Certified | P642FAX

Accurate, Extremely Robust and ATEX Certified for Hazardous Areas

Description

The P642FAX ATEX Certified, Intrinsically Safe pressure sensor is designed for use in hazardous areas across all common industrial applications.

The P642FAX intrinsically safe pressure sensor has a Titanium media connection offering compatibility with a wide range of harsh and aggressive pressure media.

The pressure sensor’s electrical output is the intrinsically safe standard 4-20mA, 2-wire signal, connection to which is made via a DIN43650 plus & socket. Pressure connection is made via a G¼” male on pressure ranges up to 1500bar, while a high-pressure F-250-C Autoclave fitting is supplied thereafter.

If you require your intrinsically safe pressure sensor to be supplied with suitable barriers please contact us with the details of your requirement and we will be pleased to source and supply them.
