Instructions for use

  • Before connection of the transducer into the pressure circuit, it is necessary to verify that the pressure being measured corresponds to the nominal range of this transducer. Even a transient loading over the maximum allowable overpressure may cause a destruction of the measuring diaphragm!
  • If you measure a pressure of such media which are not non-aggressive gases, it is necessary to verify the transducer material resistance.
  • In case of the liquid media measurement, avoid its freezing – there is a danger of the measuring sensor destruction!

Pswitch = Pnominal x UMB [V]
If there is no other request, switch is set during
production flow to Pswitch = 50% Pnominal
