Temperature input Large Displays

These large displays accept most common temperature sensors such as 3 wire PT100, Thermcouples type E,J,K,T,R,S,B,N etc.

For installations where the sensor is more than 10 metres from the display, we recommend our 4-20mA or Modbus input display with suitable amplified sensor, an arrangement which gives superior accuracy and stability in electrically noisy industrial environments.

You have a range of digit sizes to choose from, to suit the viewing distance you need.

Suited for these applications and more:-

Clean room environmental monitoring
Process temperature display
Outdoor temperature display
Computer room temperature monitoring
Meteorological display

This page has 3 display families for you to choose from:-

[Fusion] [ERXT]

[^] FUSION Series of large process displays
The FUSION is a highly precise, stable, flexible and easy to use large digit temperature display, and our top large digit seller, for both display-only and display + output applications. You can choose from digit sizes of 57mm, 102mm, 150mm, 200mm, 300mm and 400mm do suit the viewing distance in your application. We have a digit size selector which may help you to choose the best digit size for your application. It has a number of useful plug-in options which make it ideal in many control and monitoring applications. The front panel buttons can be locked, or can be operated by remotely wiring 4 pushbuttons to the display. If you need to be able to read the display in a reflection, for example in a heads-up display system, you can switch it to display a mirrored image. Interesting fact The FUSION was designed to combine the benefits of our three most popular products... The INTUITIVE (High precision, easy to use panel meter) The 1700 Series (Large digits and sealed enclosure, ideal for use outside and in large industrial environments) The Easy Reader (Economical large digit display family) We designed it, we build it, we know it inside out, so you can count on us for first class support. Plus... We are often asked to combine several fusion displays of various functions into one common display. See here for examples. Please contact us if you would like us to quote for a system to suit your requirements.
