Five Commonly Used Electrical Transducers

Electrical devices are at the heart of virtually all industrial applications. Numerous devices in various industries are capable of measuring and managing different variables such as intensity, flow, temperature, strain, and movement, among others. One such device is the sensor.

Potentiometers – These are sensors that convert the change in displacement produced by the physical quantity into change in the resistance.

Bridge circuits – These sensors convert physical quantity into voltage.

Wheatstone bridge – This type of sensor converts a quantity’s displacement to the current in the circuit.

Strain gauges – When these sensors are stretched or strained, they experience a change in their resistance. Strain gauges mainly consist of a long wire that’s able to detect minute displacement generated by the applied pressure or force.

Piezoelectric transducers – This sensor type is used to measure force, pressure, and acceleration. Once a change in the physical quantity being measured is detected, piezoelectric transducers produce a voltage that can easily be measured.
