Force measurement applications with strain sensors

Strain sensors monitor the force with which a metal sheet is held. This allows the sheet to be moved at maximum speed without it slipping or imprints occurring on it.

The bending force in fully electric bending machines is monitored during the bending process and can be recorded for quality control purposes.

Continuous force monitoring during the fusion process ensures that the created connection can meet the high stability and durability requirements.

During automatic sheet thickness measurement, the highly sensitive Baumer DSRT strain sensors detect and compensate for sheet thickness deviations. This ensures the highest possible angular accuracy of the workpiece at all times.

The weight of construction vehicles can be determined using strain sensors. This enables the loads of dump trucks to be controlled, for example, avoiding overloading. The robust design of the strain sensors guarantees reliable measurement results even when used in harsh outdoor conditions in quarries and gravel pits.

The use of strain sensors in construction machinery dampens vibrations on the placing boom of truck-mounted concrete pumps, for example. The long-term sealed and robust design also guarantees dependable continuous operation on construction sites.

Strain sensors are also used to monitor the shaft load of telehandlers. This detects overloading and prevents overturning of the telehandlers. The long-term sealed and robust sensor design also guarantees dependable continuous operation on construction sites.

Strain sensors are used on wind turbines to reliably monitor the loads on the tower or rotor blades. In this way, overloads are detected and damage to the wind turbine is prevented. The calculated service life is extended on the basis of the actual loads.

The robust strain sensors are based on strain gages. Technology. The long-term sealed strain sensors offer a cost-effective solution for measuring forces in harsh outdoor environments. They are particularly suitable for outdoor industrial applications such as vibration damping for mobile automation. Factory calibration for strain allows easy installation without calibration with a separate force sensor.
