Resistance temperature detector (RTD)
The thermometer in which the resistance of conductor changes with change in temperature is known as resistance thermometer. The resistance thermometer is also called as resistance temperature detector (RTD). Construction: The resistance temperature detector (RTD) consists of
Construction and working of RVDT (Rotary variable differential transformer)
The RVDT stand for rotary variable differential transformer is used to sense the angular displacement. It is similar to LVDT except that its core is in cam shaped and moves between the windings by means of shaft.

Advantages, disadvantages and applications of piezoelectric transducer
Advantages: There are some advantages of piezoelectric transducer which are given below, The piezoelectric transducer is available in desired shape. It has rugged construction. It is small in size. It has good frequency response. It has negligible
Difference between active transducer and passive transducer
Active transducer Passive transducer The active transducer is also called as self generating type transducer. The passive transducer is also called as externally powered transducer. The active transducer does not require any auxiliary (external) power supply. The
Working of LVDT (linear variable differential transformer)
As per the position of core, the secondary coils S1 and S2 both are produce emf which is phase. The lower end of both secondary coils S1 and S2 are joined together to get a differential output.
What are the selection criteria of transducer?
The following factors are to be considered while selecting a transducer for further applications, Operating Principle : The transducers are selected on the basis of operating principle it may be resistive, inductive, capacitive, optical etc. Operating range
Piezoelectric transducer
The piezoelectric transducers are used to convert mechanical energy into electrical energy. Asymmetrical crystalline materials such as quartz, Rochelle salt and barium titanate produce an emf when they are placed under stress. This property is used in
How pressure is measured using LVDT?
There are various methods used for pressure measurement in a process plant are, Resistive transducer. Capacitive transducer. Bellows. Diaphragm. Inductive transducer. Photo electric transducer. Piezoelectric transducer. Capsules. Bourdon tube. The pressure measurement using bourdon tube and LVDT
Classification of transducer
Transducer: The transducer is the electronic device which converts one form of energy into another form of energy. In electronic system the transducer converts non electrical signal (physical) into electrical signal. Classification of transducer: The transducer can
