An improved weight monitoring device that accurately monitors the weight of containers or other such heavy objects. The device allows for full legal loads in containers without overfilling the intended weight. A hydraulic load cell with an analog pressure transducer is coupled with an analog to digital converter to convert the analog signals into electronic digital signals which are then read by computer to determine results. The weight is conditioned by utilizing pressure and temperature amplifications, which allow the container to be zeroed and scaled to monitor the weight. This device utilizes a microprocessor to operate the electronic functions and to calculate the data. The data is stored in a read only memory chip to prevent tampering. The results can be read on sight or via downloading of information with a computer modem. The signals converted are linearly interpolated to produce highly accurate results. This device allows for timely weight reports and accurate management decisions. The load cells utilize a pre-charged chamber, or overfilling of the bladder to prevent deflection once the weight is placed upon the load cell. This load cell has a low 1 inch profile which allows for easier and less expensive installations.
