1) In an oxygen version, a ush diaphragm model is not available. In an oxygen version model CPT62I0 is only available in gauge pressure ranges ≥ 0.25

bar with media temperatures between -10 … +50 °C and using stainless steel or Elgiloy

wetted parts.

2) For the intrinsically safe version, the use of the interface and analogue output is not permitted within an explosive atmosphere.

3) O-ring made of FKM/FPM or EPDM for ush diaphragm with integrated cooling element.

{} Items in curved brackets are optional extras for additional price.

For further specications see WIKA data sheet

CT 11.02

and the order documentation.

WARNING!

For further important safety instructions for the operation in hazardous

areas see chapter “2.3 Additional safety instructions for instruments

with ATEX approval”.
