Force Sensors / Loadcells
What could be wrong with our loadcell?
LOAD CELL TROUBLESHOOTING IntroductionLoad cells are designed to sense force or weight under a wide range of adverse conditions; they are not only the most essential part of an electronic weighing system, but also the most vulnerable.Load cells might be damaged because of (shock) overloading, lightning strikes or heavy electrical surges in general, chemical or moisture ingress, mishandling (dropping, lifting on cable, etc.), vibration or internal component malfunction. As a direct result the scale or system might (zero) drift, provide unstable / unreliable readings or not register at all.This application note is written to assist users with potential load cell problems. It describes basic field tests which can be performed on site*, and provides the information necessary to interpret the results.*Proper field evaluation is absolutely critical to prevent similarly induced damage in the future! Under no circumstances should fault location, as described below, be attempted on load cells installed in a hazardous area! IN GENERALCarefully check the system integrity before evaluating the load cells:- check for force shunts (might be caused by dirt, mechanical misalignment or accompany¬ing components such as stay- or check rods.- check for damage, corrosion or significant wear in the areas of load introduc¬tion.- check cable connections to junction box and indicator.- check the measuring device or indicator with an accurate load cell simulator.Visually inspect the load cells before performing the tests as described on the following pages. Pay particular attention to signs of corrosion (especially around the critical gauge area), the integrity of the cable (might be compromised due to cuts, abrasions, etc) and the condition of the cable entry. The following test equipment is required to properly evaluate a load cell:- A high quality, calibrated, digital volt- and ohmmeter with a measuring accuracy of ≤0.5Ω and ≤0.1 mV, to measure the zero balance and integrity of the bridge circuit.- A megohm meter*, capable of reading 1000 Mohms with a resolution of 1 MΩ at 50 volts DC, to measure the insulation resistance. *Do not use megohm meters which supply more than 50 volts to the load cell, in order to prevent permanent damage!- Or use a portable multifunctional calog hand held tester. - A means to lift the dead load (weighbridge, tank, hopper, conveyor, etc.) off the load cell to be able to measure the zero balance or to remove the load cell(s), i.e. a crane, hydraulic jack, etc.Load cells are produced according to specifications and tolerances which are described in the applicable data sheet. More detailed information can be found on the calibration sheet which is packed with each load cell. The calibration sheet mentions the exact values for the input and output resistance, insulation resistance, zero balance, rated output and the correct wiring code; it provides an important reference for the values which can be measured and should be filed with the system...
