Piezoresistive elements can be ceramic or plastic. They generate electricity when compressed.
A Crankshaft sensor is primarily used for speed sensing. It follows the principle of a rotary encoder. Another important function of the Crankshaft sensor is to ensure synchronization of operation between the Crankshaft and Camshaft with the help of Camshaft sensor. The sensing wheel contains a series of equispaced drilled hole or slots. Usually there will be one longer slot or a missing slot which will be used to position the Crankshaft absolutely with respect to the TDC of the first Cylinder. This positioning of the Sensing wheel is compared with the positioning of a similar sensing wheel on the Camshaft to ensure synchronous operation.

Most externally mounted overload protection devices operate on the principle of monitoring the current flowing through an electrical circuit. When the current exceeds a predetermined threshold, indicating an overload condition, the device triggers a protective mechanism, such as opening a circuit or tripping a breaker, to prevent damage to the equipment. These devices often use thermal or magnetic sensing elements to detect excessive current levels and act quickly to interrupt the power supply. This ensures the safety of electrical systems and prevents overheating or equipment failure.
rms value is measured using voltmeter with the use of heat sensing elements.
Pressure gauges work based on the principle that a fluid or gas exerts a force on the gauge's sensing element, which then deflects or moves in response to the pressure. This deflection is converted into a reading that indicates the pressure being measured. The gauge is calibrated to provide an accurate and precise measurement of the pressure exerted on the sensing element.
