    The MP85A measuring system The MP85A measuring system comprises the PME Assis- tant program and the PME MP85A or MP85A DP hard- ware. The MP85A DP is provided with a PROFIBUS inter- face in addition to the CAN bus and Ethernet interface.

    Starting with firmware version 2.22 the limit value results can be included into the OK/NOK evaluation with all mon- itoring methods. There is also Version MP85A-S for switch and haptic test with tolerance windows. However tolerance band moni- toring is not possible with these devices.

    With the program a new firmware version can also be transferred to several devices simultaneously.

  • Page 26 Potentiometer types of transducer are often used for the measurement quantities of displacement and angle. A measuring range of 1 V/V is set automatically for these transducers (fix); internally, the MP85A uses the same circuit as for half bridges. We recommend that the characteristic is measured this type of transducer.
  • Page 27 Prepare MP85A for your application LVDT The LVDT principle (Linear Variable Differential Trans- former) is often used for inductive displacement trans- ducers where the measuring ranges are 500 mV/V up to 1 V/V. However, displacement transducers with a half bridge and output signals below 100 mV/V are also common, so check the details in the data sheet.

In other words: for linear force sensors, the outgoing signal is twice as high when the force is double.
