The LCIC-WIM is a high speed, intelligent load
cell interface card with USB/RS-232/RS-485 interfaces.
Besides its basic mode, the board includes an integral
Fill Mode supplying an independent filling control.
The board is intelligent and powerful enough for OEM
customers—it is ready to accept piggy-back modules
and/or embedded applications for OEM special
requirements. The LCIC-WIM-BEN is useful
in applications such as analyzing noise and vibration in
a belt conveyor or any dynamic weighing system, for
example the time it takes for stabilization after a load
was applied. Other potential applications include
checking scale behavior for slow/high speed WIM
(weighing in motion) applications, measuring maximum
(peak) and minimum forces on a scale/testing machine
(helps to select the suitable load cell for optimum
performance), and running tests and getting immediate
final weight results on WIM and check weighers.
LCIC-WIM Software
Three software utilities are supplied with the board:
LCIC-WIM-CALIBRATION, LCIC-WIM-SETTINGS and
LCIC-WIM-MONITOR. These software utilities enable
easy selection and setup of the required board.
The calibration utility (LCIC-WIM-CALIBRATION)
enables you to calibrate the LCIC-WIM-BEN board by
adjusting it to your own system. The utility is straight
forward and is in the form of a Windows® wizard.
The LCIC-WIM-SETTINGS utility gives control to card’s
filters, analog output, fill mode parameters and more.
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 speed (15,000 samples per
second), sending the data to the PC via the USB port
and displaying it as a curve—load cell signal/versus time.
You can then zoom in/out on the data, view max (peak)
and min readings, save the data in standard ASCII file
format for later use and even perform some calculations
like averaging on a required part of the curve.
