I.M.S

For PC/AT or Compatibles

Stand-alone microcomputer-based interface board that was especially designed to fit very fast real-time weighing applications. Requires no other interfacing accessories for the load-cells or the outputs.

Typical Applications

• Multi-head rotary filling machines.
• Multi-scale processing.
• High-speed checkweighers (multi-channel).
• Batching controllers.

Four Channel Load Cell Interface Card Model LCIC-4HS The LCIC-4HS is a four channel load-cell interface board for the IBM PC/AT and compatible computers (ISA Bus). This board was especially designed to fit very fast and real-time weighing applications such as multi-head fillers. It supports up to four channels with one load-cell on each. All the necessary filters and the batching control functions are built on the board and are easily accessible by the user. Direct communication with the PC bus and high-frequency sampling enables the LCIC-4HS to handle all real-time applications and to achieve very high accuracy. The LCIC-4HS is memory-mapped. Up to 32 boards (128 channels) may be installed in a single PC. It comes with a detailed user manual and software utilities for easy installation and calibration as well as full examples for the programmer (including Win 95/98 drivers).

Main Features

• User-friendly calibration procedure (software provided).
• All necessary filters to avoid vibration noises are built on-board.
• Calibration parameters reside in the LCIC-4HS memory.
• No auxiliary power supply required.
• Very fast sampling rate: 500 samples per second for all four channels.
• Built-in batching control function, accessible by the user application program.

Hardware Specifications

• Excitation voltage: 8.1 VDC.
• Internal A/D resolution: 16 bit.
• Display resolution: up to 1/10,000 from the net weight.
• Internal A/D conversion time: 40,000 per second.
• Updating PC bus speed: 500 samples per second for all four channels.
• Number of load-cells: one per channel 350 W.
• Load-cell connection method: four or six wires.
• PCB type: full size multi-layer (six layers).
• Method of communication with the PC bus: dual port RAM (memory mapped).
• Up to 32 cards may be installed in one PC.
• Filters: built directly on-board and may be adjusted by the user.
• Eight isolated inputs and eight isolated outputs.

Dimensions

• Full-size PC board plus small PCB with four connectors for load-cells.

The LCIC-WIM Monitor utility is a vital tool for analyzing dynamic load/force systems. It takes full advantage of the board's speed and samples the load cell signal at maximum samples per second, sending the data to the PC via the USB port and displaying it as a curve - load cell signal/ versus time. Customer than able to zoom, keep the data in a standard file for later use and even running some calculations like averaging on a required part of the curve.

Main Features:

• Update the PC via USB at a rate of ~15,000 sample per second
• Display a curve of load cell signal versus time with options for zoom in & out
• Shows Max (peak) and Min readings
• Keep all results in a standard ascii file for later use
• Option to read results after filtering - helps choosing the right on-board filter
• Option to do immediate averaging on the relevant part - helps to see immediate results for applications like WIM and Checkweigher.
• Separate viewer utility allows to read and analyze the saved file at any PC
• Curve and file results might be printed for hard copy

Typical applications for monitoring:

• Analyzing noises and vibrations in a belt conveyor or any dynamic weighing system; for example the time it takes for stabilizing after a load was applied
• Check scale behavior for slow / high speed WIM applications
• Measuring max. (Peak) and min. forces on a scales / testing machines - helps to select the suitable load cell for optimum performance.
• Running tests and getting immediate final weight results on WIM and Checkweighers.

Samples:

Fits also high-speed Checkweigher systems, provides excellent accuracy

The LCIC-WIM with the embedded Checkweigher application, was designed to function as a Universal High- speed  In-Motion Checkweigher controller;

It will work as a stand-alone controller or, might be connected to a PC running our Checkweigher Monitoring program that provides the user with much more details like: statistics, histogram, history etc.

The controller can be easily used for a new Checkweigher or, to retrofit old systems that are mechanically serviceable but, either have a non-functioning controller, or customer is seeking for better performances and accuracy.

Main features:

* High-speed; Checkweigher can handle even 10 parts per  second

* On board programmable rejection output

* Easy to program and enter set points from any notebook

* Keeps in memory 3 different products for easy change

* Shows results on board's display, allow using it without a PC

* USB / RS232 communication port

* User friendly PC monitoring application
