What is a Transducer ?

Transducers play an important role in the field of instrumentation and control engineering. Any energy in a process should be

Linear Variable Displacement Transducer (LVDT): A very basic transducer which is always useful in the field of instrumentation, I have

Principle of Strain gauge load cell When steel cylinder is subjected to a force, it tends to change in dimension.

A bimetallic strip is made up of metal A and B, having different thermal expansion co-efficient. It is bonded together.

Bourdon tube pressure gauge when an elastic transducer ( bourdon tube in this case ) is subjected to a pressure,

Principle of Elastic diaphragm gauges when an elastic transducer (diaphragm is this case) is subjected to a pressure, it deflects.

Strain Gauge Pressure Sensor Principle : When a closed container is subjected to the appilied pressure, it is strained (that

There are two types of control systems namely: Open loop control systems (non-feedback control systems) Closed loop control systems (feedback

Home furnace control system must control the temperature in the room and kept it constant. As in open loop system

Principle of Pneumatic Load Cell If a force is applied to one side of a diaphragm and an air pressure
