    Chapter 5 Parameter Guide. Once you are satisfied with the installation, and the dBi Series Intelligent Transducer is reading what you would expect in terms of distance from the face of the transducer to the material level, then you can proceed with any programming, required for the intended application.

  • Page 24: Chapter 4 Getting Results From Your Dbi Sensor

    Near blanking (P107) is the distance from the face of the transducer that the dBi Series Intelligent Transducer will not record a level nearer than. A typical reason to increase this from the default value would be if you wish to ignore close in obstructions.

  • Page 33: Breakpoints

    PULSAR MEASUREMENT Breakpoints P610-P641 Level/Volume Breakpoints These parameters are used to create a profile of the vessel when P600=11 (universal linear) or P600=12 (universal curved). You should enter breakpoints in pairs, a reading for level and its corresponding volume. The more pairs you enter, the more accurate the profile will be.

  • Page 34: Tables

    DBI (PROFIBUS PA) INSTRUCTION MANUAL Universal Curved (P600=12) This volume calculation creates a curved approximation of the level/volume relationship, and works best if the vessel is non-linear, and there are no sharp angles. You should enter 2 level/volume breakpoints at the minimum and maximum levels, and several for each place where the vessel has got an arc.
  • Page 35 PULSAR MEASUREMENT P808 Fail-safe Mode By default, if a fail-safe condition occurs, then the display, relays and the mA output are held at their last known values until a valid reading is obtained. If required, then you can change this so that the unit goes to high (100% of...
