4-20mA, 0-10V process input bargraph displays
Display almost any physical variable... The bargraph displays on this page accept most common process signals such as 4-20mA, 0-10V, 1-5V etc. All can be scaled to read in your preferred engineering units.
Most have a 24V excitation output voltage which you can use to power a 2 wire or 3 wire input loop.
Suited for these applications and more:-
- Level measurement - use a depth or level sensor
- Pressure measurement - use a pressure transmitter sensor
- Tank contents display - use a level sensor
- Temperature measurement - use a temperature transmitter
- Humidity measurement - use a humidity transmitter
- Any physical variable having a 4-20mA or 0-10V signal

The BAR-X and BAR-A are user friendly programmable process bargraph displays.
The BAR-A is for display only, the BAR-X includes 2 alarm relays.
They can mount either vertically or horizontally and are unique in their ease of setup - programmable, but without menus!
A fully customisable scale sheet fits behind the protective front window, to allow you to read off the value in your own engineering units.
