Claim 0:
1. A device for calibrating a weighing system, the weighing system comprising a tank having, at a lower portion, a plurality of support legs, the calibration device comprising:
at least one calibration module, such that each calibration module is adapted at an upper end for fixed connection to an upper part of a corresponding one of the support legs and a lower end is adapted for fixed connection to a foundation;
a hydraulic system connected by a hose to each calibration module for applying a force to the tank;
a calibration terminal, connected to each of the at least one calibration modules for real time display of the force applied to the tank;
a calibration load cell in each calibration module for converting the applied force from the calibration module into an analog signal; and
at least one analog-to-digital (“A/D”) converter for converting the analog signal into a digital output signal;
wherein, for each calibration load cell, a corresponding:
one of the A/D converters is located at the calibration terminal for converting the analog signal and providing a digital output signal for processing at the calibration terminal;
one of the A/D converters is located at the calibration load cell for converting the analog signal and providing a digital output signal for processing at the calibration terminal; or
smart junction box is provided, having an A/D converter for each calibration load cell, for converting the analog signal received therefrom and providing a digital output signal per calibration load cell for processing at the calibration terminal.
