Load Cell Interface for WIM

Very High Speed, Intelligent Load Cell Interface Card with USB/RS232/RS485

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:

1. WIM– Weighing Trucks & Trains in motion. Fits HS (high speed) and LS.

2. LIW – Loss In Weight rate controller for continuous feeding to a process.

3. Batching & Filling controller – Stand alone controller for high speed net-weight fillers. Example: Bag filling machine.

4. Checkweigher – Makes the board a stand-alone controller that fits most common Checkweighers. It includes outputs for rejects.

5. Force measurement & Monitoring forces – useful monitoring utility, a vital analyzing tool for all dynamic load and force measurement applications.

6. High speed in-motion weighing controller – To weigh packages while passing over a conveyor.
