BESKRIVELSE

Bargraph displays are ideal if you want to know the ‘fullness’ of a tank, ‘hotness’ of a process etc. Use them in applications where you want to be able to know, at a glance, the relative value of a variable. Similar in principal to moving pointer displays, yet more reliable and robust because they have no moving parts.

Choose from 2 models:
The BAR-A is a display-only version
The BAR-X has 2 alarm relays
