Weighing In Motion

Very High Speed, Intelligent Load Cell Interface Card

with USB/RS232/RS485

PDF Version

The LCIC-WIM was designed to fit the most demanding real time weighing and force measurement applications.
On the one hand, a very fast load cell interface allows users to capture the data at around 18,000 samples per second.
On the other hand, it is equipped with a powerful processor, 8 I/O, analog output and display that allows it to run embedded applications.
This is for customers that require real-time and immediate response.

Comes ready with embedded algorithms for these applications:

  • WIM- Weighing Trucks & Trains in motion. Fits HS (high speed) and LS.
  • LIW - Loss In Weight rate controller for continuous feeding to a process.
  • Batching & Filling controller - Stand alone controller for high speed net-weight fillers. Example: Bag filling machine.
  • Checkweigher - Makes the board a stand-alone controller that fits most common Checkweighers. It includes outputs for rejects.
  • Force measurement & Monitoring forces - Our useful monitoring utility, a vital analyzing tool for all dynamic load and force measurement applications.
  • High speed in-motion weighing controller - To weigh packages while passing over a conveyor.
