Pressure transducers are devices that exhibit a change in resistance inversely proportional to a change in pressure.
Thermocouple connections must be taken into account to ensure a high degree of accuracy.
The change in value of the analog signal during the sampling process produces what is called the quantization error.
A basic sample-and-hold circuit consists of an analog switch, a capacitor, and an instrumentation amplifier.
Noncontacting displacement transducers include optical and capacitive transducers.
A strain gauge uses the principle of capacitance for its operation.
Displacement, velocity, and acceleration can all be measured by using specific motion transducers.
The triac provides better dc power control than the SCR.
A resistance temperature detector produces a voltage for a given change in temperature.
The SCR is ideal for ac applications.
