Fusion Large displays let you clearly see important information from a distance. We make large displays which accept most industrial process signals such as 4-20mA, 0-10V, 1-5V etc. These are ideal for crane load displays, weighbridge displays, temperature, humidity, power, RPM etc.



This family accepts the following signals and sensor types:-

• Any DC voltage from 0-12V
• Any DC current from 0-25mA
• 2, 3 or 4 wire 4-20mA humidity transmitters
• 2, 3 or 4 wire 4-20mA pressure transmitters
• 2, 3 or 4 wire 4-20mA load cell transmitters
• 2, 3 or 4 wire 4-20mA temperature transmitters
• 2, 3 or 4 wire 0-10V amplified signal transmitters
• 3 wire position / length / angle potentiometer inputs

These can be easily scaled to read your process variable, thanks to a unique user-friendly Fusion calibration system. Displays are available to show your measurement in 3,4,5 or 6 digit format. We can also print units text on the display to show ^oC, Bar, %rh, mmHg, litres, gallons, tonnes etc.

What size characters do I need?

With London Electronics displays, you have a wide choice of character heights for different viewing distances.

You should measure the maximum viewing distance you'll need, and use this calculator to work out the ideal character size for you.

This will make sure you won't have to struggle to read the display. And, you won't pay too much for a display which is bigger than you need.
