Pressure sensors/transmitters for Oxygen systems

[jesper.stougaard]

Hi, 

I have a project where we are supposed to install some pressure transmitters (25 / 250Bar - 0-10VDC or 4-20mA) in a sealed pipework system, these sensors/transmitters needs to be approved for use in contact with Oxygen systems (O2).

1) Do we in Schneider have such pressure sensors, if yes which types?

2) How can I see that they are approved/certified for use with Oxygen, is there a ISO/EN standard that I can relate to?

Regards Jesper.

I usually try to get the factory to do oxygen cleaning because I don't trust the 3rd party operations working out of a garage somewhere.  I've always used stainless materials of construction, I'm not sure elastomers can be oxygen cleaned.

The standards for oxygen cleaning that I see referenced are ASTM G93 or CGA 4.1.

The delivered product is usually bagged/packaged and marked Oxygen cleaned.

I've never used a Schneider product that was oxygen cleaned, but I can't imagine Schneider does not offer the service.
