1 Answer

Answer :

* In an instrumentation system, a transducer is used for sensing various parameters. The output of transducer is an electrical signal proportional to the physical quantity sensed such as pressure, temperature etc. * However the transducer output cannot be used directly as an input to the rest of the instrumentation system * In many applications, the signal needs to be conditioned and processed. The signal conditioning can be of different types such as rectification, clipping, clamping etc. Sometimes the input signal needs to undergo certain processing such as integration, differentiation, amplification etc.

* Application 

1) Electronic weighing scale

2) Temperature indicator

3) Temperature controller

4) Pressure monitoring and control

5) Light intensity meter

6) Measurement of flow and thermal conductivity
