    Tightening can cause damage, e. g. to the rotation mechanism of the housing. If there is strong vibration at the mounting location, the instrument Vibrations version with external housing should be used. See chapter "External housing". WIKA Operating Instructions - Process pressure transmitter IPT-2x...

  • Page 15: Ventilation And Pressure Compensation

    When quickly opening/closing the housing cover, the measured value can change for approx. 5 s by up to 15 mbar. For an effective ventilation, the filter element must be always free from buildup. In case of horizontal mounting, turn the housing so that the filter element points downward after the instrument is installed. This provides better protection against buildup. Caution: Do not use a high-pressure cleaner. The filter element could be dam- aged, which would allow moisture into the housing. The following paragraphs describe how the filter element is arranged in the different instrument versions. WIKA Operating Instructions - Process pressure transmitter IPT-2x...
