  •   The working principle of compression weighing transducer

      A load cell is a transducer, which measures force and outputs the force as an electrical signal. Most load cells use strain gauges to detect the measured value, but hydraulic and pneumatic load cells can also be used.

      Strain gauge load cell

      Strain gauge load cells usually have four strain gauges in a Wheatstone bridge configuration, which is a circuit that balances two branches of a bridge circuit.

      In this type of load cell, the measured force deforms the strain gauge, and the deformation is measured as a change in an electrical signal. There are several common strain gauge load cell configurations, including shear beam, S-type, and compression.

      How does the load cell manufacturer's compression weighing transducer work?

      Essentially, a compression load cell is a module designed to hold the load at one point to measure the compression rate. Tension dynamometers measure tension, while compression dynamometers measure thrust along a single axis. Usually, the compression load cell is placed under the object to be measured.

      As mentioned earlier, when a load is applied, the strain gauge in the compression dynamometer deforms, and this deformation is used for measurement.

      Depending on the application, a weighing transducer can be used to determine any relative change in resistance. Using Wheatstone bridge circuits can measure these relative changes with high accuracy, ensuring reliable results.

      Compression load cells are usually made of rust- and scratch-resistant materials because the substrate should be free of any deformation to provide accurate results. A hardened cover plate is usually used on the substrate to ensure this.

      Compression load cells are specifically designed for applications with limited space, and they can be made very compact. They are also ideal for extremely high loads-HBM’s compression load sensors can provide loads up to 50 tons.

      These load cells are very accurate and useful in industries where products are sold by weight. Many compression load cells are single-point, they are extremely versatile, and can measure eccentric loads, which helps to ensure accuracy. Compression load cells also have long-term stability, and regular load cell calibration services provided by companies such as HBM can further ensure this stability and accuracy.

      Compression load cells are easy to measure, help speed up processing and output, reduce the time it takes to obtain results, and ultimately reduce costs.
