cating instrument VEGADIS 50

Note:
The four-wire connection cable to VEGADIS
50 should be screened and have a max.
length of 25 m. The digital signals to the indi-
cating instruments would otherwise be im-
paired by the cable capacitance of longer
connection cables. Ground the cable screen
together with the signal cable screen on the
sensor.
