1) For variant 1 and 2: The low ambient temperature -40 °C applies to models with Limatherm or Rosemount cases. The low ambient
temperature of either -40 °C or -60 °C applies to models with WIKA connection head series 1/4000, 5/6000, 7/8000. For explanation
of symbols for low temperature range see chapter 2.5 “Labelling, safety marks”
2) The temperature class depends on the ambient temperature.
3) The parameters for variant 2 and variant 3 Transmitters have to be taken out of the related operating instructions.
When there is a built-in transmitter and/or a digital display, the special conditions from the
type examination certificate (see chapter 4 “Special conditions for use (X conditions)”)
apply.
