Now the frequency waves enter into an amplifier which will amplify the frequency waves into the required level. So, thermocouple is… Many transducers have an input that is then converted to a proportional electrical signal. Piezoelectric Transducer Contents hide 1. The production of the signal depends on the resistive inductive and capacitive effects of the physical input. A primary transducer is used to change the physical quantity to the mechanical signal whereas a secondary transducer is used to convert a mechanical signal to an electrical signal. Although the transducers referred to in these notes are specifically those manufactured by Carrel and Carrel Ltd much of the information given can be applied to transducers in general. As mentioned earlier, mechanical transducers are a set of primary sensing elements that respond to changes in a physical quantity with a mechanical output. Measuring electrical quantities using transducers confers a number of advantages. They produce an electrical signal proportional to the input (physical quantity). Transducers which require an external power source for their operation is called as a passive transducer.

Such mechanical device are called as the primary transducers, because they deal with the physical quantity to be measured. (b)Convert the inputs into a different parameter such as the conversion of current and voltage signals into a power signal. Low-pressure elements have only two or three coils to sense the span of pressures required, however, high-pressure sensing may require up to 20 coils . On the other hand, Rochelle Salt provides highest output but its main drawback is that it can only be used over a limited temperature range (up to 45°C only) and it has to be protected from moisture. Here input quantity is non-electrical quantity. As the diaphragm flexes in response to pressure changes, it changes the electrical characteristics of the coil or capacitor. Common inputs include energy, torque, light, force, position, acceleration, and other physical properties. If we have non electrical quantity, then if we want do some electrical processing over it, like for measurement, manipulation and for the control systems we have to apply electrical methods, we have to convert non electrical quantity into electrical quantity and that’s why there is a need for the development of the transducers.
