In Line Load Cell Amplifiers and Load Cell USB

Our new range of In Line Load Cell Amplifiers and Load Cell USB modules enable you to quickly download and analyse data from your load cells directly into your PC.

Please note, these in-line conditioners are only available to buy with our range of new load cells – we do not sell them separately.

Miniature In Line USB module

This module allows you to plug your load cell directly into your PC/Laptop via the USB port. Data can then be viewed and logged on your PC. The logged data can be loaded into Excel and many other spreadsheets to produce graphical reports etc. Multiple load cells can be connected to your PC in this way and our free software allows you to display and log of up to 24 channels simultaneously (maximum channels may be dependent on PC). Power to the load cell is supplied by the USB port, so no external power supply is needed. See below for PC screen shots.

Dimensions: 58mm x 33mm x 13mm
Cable length from USB connector to module: 250mm
Total cable length: as selected in termination option)

Miniature In Line Load Cell Amplifier

This module amplifies the load cell signal into a number of more usable outputs. Outputs available are:

  • 0-5
  • 0-10V
  • +/-10V
  • 4-20mA.

Dimensions: 27mm Diameter x 13mm

Normal cable length from load cell to module: 250mm [call if you’d like a different configuration]
