Product operation

6.1. Measuring principle

High frequency microwave pulses are guided along a steel cable, a rod or a coaxial cable. 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 consuming adjustment with medium is not necessary. The instruments are pre‑set to the ordered probe

length.

The shortenable cable, rod and coaxial variants 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 8188. Optionally, parameters may also be uploaded and

downloaded with the display/configuration module or saved in a file by using PACTware™/8188‑DTM.

Set up with display/configuration module

Display/configuration module

Description

The display/configuration module can be inserted into the measuring device and removed

again at any time. It is not necessary to interrupt the power supply. The measuring device is

adjusted via the four keys of the display/configuration module.

The measuring device can be operated thanks to PACTware™, via

HART communication. An interface adapter is necessary for the

adjustment with PACTware™. For the setup of the Type 8188, the

DTM in the actual version must be used. The basic version of DTM

incl. PACTware™ is available as a free-of-charge download from

the internet at www.burkert.com .
