PC-CAT allows convenient remote control of all functions of the signal converter. The vessel can
be shown in schematic form together with the associated measured values and the measured
spectrum. A trend graph of the output signal and threshold signal strength is also provided. All
relevant instrument data can be recorded in the form of a data set small enough to be stored on a
floppy disk or transferred electronically. Stored data can also be used for configuring other units
of the BM 70 product line.
PC-CAT files can later be used to analyse the performance of the level gauge. All graphs and
screens can be exported a word processing systems or other programs.
The customer’s PC containing PC-CAT is connected to the current output via the supplied PC
adapter, max. distance from the level gauge: 1000 m or 3300 ft. The PC adapter has no effect on
in-line instruments such as milliamperemeters, recorders, etc., connected to the current output.
