In Line Load Cell Amplifiers and Load Cell USB |
 |
 |
|
 |
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: 56mm x 31mm x 12mm - cable length from USB connector to module 150mm - total cable length is 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 0-5V, 0-10V, +/-10V and 4-20mA. (Dimensions: 25mm Diameter x 12mm - normal cable length from load cell to module 150mm [call if you'd like a different configuration] - total cable length is as selected in termination option).
