Hydraulic load cells

For the purpose of measuring forces, hydraulic load cells use fluid pressure. As a result of the force applied, the fluid is compressed, causing a change in pressure that may be noticed and converted into an electrical signal.

Pneumatic Load Cells

Similar to hydraulic load cells, pneumatic load cells function by using air or gas as opposed to liquid. By compressing the gas, the delivered force results in a pressure change, which is recorded and transformed into an electrical signal.

Piezoelectric Load Cells

Piezoelectric load cells use the piezoelectric effect to measure forces. Whenever a force is applied, the load cell produces an electrical charge proportionate to the applied force that may be measured and turned into an electrical signal.

Capacitive Load Cells

With the application of force, capacitive load cells measure fluctuations in capacitance.
The load cell deforms as a result of the applied force, causing a change in capacitance that may be measured.

Calibration of Instron Load Cells

In order to preserve Instron’s accuracy and dependability, calibration is essential. The load cell’s accuracy is ensured through routine calibration, enabling accurate force analysis.
