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.
