Instructions for use

  • Before connection of the module 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.
  • The manufacturer is not responsible for damages caused by improper installation.
