Application Of Resistive Strain Sensors

for Measuring the Physical Values

The required physical values can be determined by measuring the strain of working medium caused by force, pressure, displacement, etc. The strain is measured by resistive strain sensors. The below figures show examples of various parameter measurements using resistive strain sensors:

Force Measurement
A resistive strain sensor attached to the working medium of the sensor, which serves as support for weight or applied effort, can measure the force directed at this support or the weight lying on it.

The sensors can be selected in the following sections:

  • Force sensors
  • Strain gauge sensors
  • Resistive strain sensors

Vibration/Acceleration Measurement
A resistive strain sensor attached to a thin elastic plate allows to measure the frequency and the amplitude of the vibration and acceleration affecting this plate.

The sensors can be selected in the following sections:

  • Accelerometers
  • Resistive strain sensors

Pressure Measurement

A resistive strain sensor attached to a diaphragm (membrane) allows to determine the air or liquid pressure on this diaphragm. The resistive strain sensor is typically attached to the back of the diaphragm to avoid sensor damage due to direct pressure of air or liquid.

The sensors can be selected in the following sections:

  • Pressure sensors
  • Resistive strain sensors

Measurement of Displacement

A resistive strain sensor attached to an elastic element allows to determine the bending force on this elastic element, thus enabling to measure the displacement that caused this bending force.

The sensors can be selected in the following sections:

  • Displacement sensors
  • Resistive strain sensors

Torque Measurement

A resistive strain sensor attached to drive shaft of car engine or torsion shaft of drilling machine allows to measure the transmission force, i.e. the torque of this shaft.

The sensors can be selected in the following sections:

  • Torque sensors
  • Resistive strain sensors
