  • False Trip ? What is happening ?
    The vibration velocity seems below the full scale range of the sensor unfortunately the sensor output is saturating .....
    MEMs based sensors have limited dynamic acceleration. When these limits are exceeded they have nonlinear output that lead to false trip. Piezoelectic sensors are by nature linear and almost not limited in acceleration range.
    For example some customers exhibit false trip when they encounter pump cavitations, sticking bearings, bearing lubricant failure, ... .

    Recommendations :
    Use our premium MEMs based  (model 425.51) vibration transmitter  with 100 g dynamic.
    Use our premium Piezo based (model 125.01) vibration transmitter with 2000 g dynamic.
  • What Connector / cable is recommended ?
    For standard application; we recommend our M12 epoxy seal connector.
    M12 or Mil glass seal connector is recommended for lifetime hermetic sealing warranty. It is also interesting when harmful gas are present in the process.
    For underwater application we recommend our IP68/IP69K integral polyurethane cable which has been successfully tested down to 150 meters.
    For best chemical resistance, we recommend our IP68/IP69K integral FEP cable.
    For really harsh environment our IP68/IP69K teflon FEP cable with stainless steel overbraid is the perfect solution.
