Product operation

6.1. Measuring principle

High frequency microwave pulses are guided along a rod. When they reach the product surface, the microwave pulses are reflected

and received by the processing electronics. The running time is evaluated by the instrument and outputted as distance. Time con-

suming adjustment with medium is not necessary. The instruments are pre-set to the ordered probe length.

The shortenable rod version can be adapted individually to the local requirements.

6.2. Product operation notes

Note:

The measuring device can be adjusted with:

• The display/configuration module

• The suitable Bürkert DTM in conjunction with a software according to the FDT/DTM standard, e.g. PACTware™ and PC

• With a HART handheld

The entered parameters are generally saved in the measuring device Type 8189. Optionally, parameters may also be uploaded and

downloaded with the display/configuration module or saved in a file by using PACTware™/8189-DTM.
