1) As an oxygen version, a flush diaphragm model is not available. In an oxygen version, the model CPT62I0 is only available in
overpressure ranges ≥ 0.25 bar (≥ 0.4 psi), with medium temperatures between -10 … +50 °C (14 … 122 °F) and using stainless
steel or Elgiloy
®
wetted parts.
2) It is defined by the total measurement uncertainty, which is expressed with the coverage factor (k = 2) and includes the following
factors: the intrinsic performance of the instrument, the measurement uncertainty of the reference instrument, long-term stability,
influence of ambient conditions, drift and temperature effects over the compensated range during a periodic zero point correction.
3) Reference conditions: 15 ... 25 °C (59 ... 77 °F)
