Load Cell Product
Model 11 Miniature Load Cell with two vent holes, 250-pound range.
Load Cell Application
The customer needs to measure the force on a hydraulic cylinder in a down-hole well logging tool. The pressure inside the oil-filled tool can reach 20,000 psi, which will cause the load cell to give false readings as if it were a pressure transducer.
Solution to Load Cell Application
We drill two holes on opposite sides of the Model 11 Miniature Load Cell element to allow the ambient pressure in the tool to be on both sides of the load cell element. While one hole would work, two are provided to facilitate cleaning (flushing), if necessary.
