Frequency Generating Transducer:
Frequency Generating Transducer – Unlike variable parameter analog transducers, frequency and pulse generating transducers measure physical variables in terms of a pulse repetition rate.
Since frequency is an analog quantity, these can be treated as either analog or digital devices. Therefore, any phenomenon to be measured is converted into a corresponding rate of pulse generation which undergoes counting process and is made digital in nature.
These transducers produce a simple series of voltage or current pulses or cycles in proportion to the change in the physical parameter being measured. The series of pulses can be counted over a certain precisely determined period of time and the input magnitude can be known with considerable accuracy.
