Loadcell input Large Displays
These large displays accept standard loadcells. They can easily be scaled to read in your preferred engineering units.
Because the scaling is digital, stability and accuracy is excellent.
The displays have an excitation output voltage which you can use to power the loadcell bridge.
You have a range of digit sizes to choose from, to suit the viewing distance you need.
This page has 2 model for you to choose from:-
[FUSION] [L175X]
|
The FUSION is a highly precise, stable, flexible and easy to use large digit loadcell / weighing 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.
It also has a 10 point linearising function, which lets you correct for non-linearities in the sensor, or for curved-sided containers.
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.

The L175X series is a family of sealed load/weight displays which can be wall mounted, suspension mounted or panel mounted.
They offer a wide range of digit sizes, brightness options, and led colours.
They can also be used to create custom-made multi-line numeric displays for production monitoring and displaying general manufacturing performance.
Scaling and adjustment can be done remotely.
Please note: These are older displays which are approaching obsolescence. Please consider the FUSION series for all new projects.
