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

Model BAR-A and BAR-X
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.
