Load Cells (Electrical Resistance) | Model 3000
The Model 3000 Load Cell is made from an annulus of high-strength steel or aluminum, with electrical resistance strain gages in a Wheatstone Bridge configuration. The load cell is designed primarily for use on tiebacks and rockbolts, although they may be used during pile load tests and for monitoring loads in crosslot struts and tunnel supports, etc. In most cases, the load cells are used in conjunction with a hydraulic jack and bearing plates.
The hydraulic load cell uses a conventional piston and cylinder arrangement with the piston placed in a thin elastic diaphragm. The piston doesn’t actually come in contact with the load cell. Mechanical stops are placed to prevent over strain of the diaphragm when the loads exceed certain limit.
The load cell is completely filled with oil. When the load is applied on the piston, the movement of the piston and the diaphragm results in an increase of oil pressure. This pressure is then transmitted to a hydraulic pressure gauge via a high pressure hose.
Loadcells are devices used to measure force or weight in a variety of industries, from manufacturing to transportation. To ensure accurate readings and reliable operation, regular loadcell calibrations are essential. Calibration is the process of comparing a loadcell’s output to a known standard, typically a weight that has been calibrated to a national standard. This process helps to identify any errors in the loadcell’s output and adjust it to the correct value.
Proper loadcell calibration can help to prevent costly errors and equipment failures, as well as ensure the safety of workers and products. Loadcell calibrations should be performed by trained professionals using specialized equipment and procedures to ensure accurate and reliable results. Regular calibrations can help to extend the lifespan of loadcells, reduce downtime and maintenance costs, and improve overall product quality.
