#electrical transducers

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.
