1) In an oxygen version, a flush 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 flush diaphragm with integrated cooling element.
