Advantages and disadvantages of piezoelectric transducer

When an external force is applied to this transducer, the produced voltage that can be measured easily. This change is measured by its corresponding value of sound or some of the vibration. There are many different types of transducer available but piezoelectric transducer are some of the advantages compare to other transducers. So this page is given below some advantages and disadvantages of the piezoelectric transducer are given below:

 There are some advantages of the piezoelectric transducer which are given below:
  • The piezoelectric transducer has a good frequency response
  • It is small in size
  • It is easy to handle  because of its small dimension
  • It has rugged construction
  • It is available in the desired shape
  • It has a negligible phase shift
  • Natural quartz and barium titanate can be made any desired form and shape
  • It offers high output that is measured in the electronics circuit
There are some disadvantages to the piezoelectric transducer which are given below:
  • It has high-temperature sensitivity
  • Some crystals are water soluble and dissolve in a high humid environment
  • The piezoelectric transducer is used for dynamic measurement only, not suitable for static conditions
  • It needs high piezoelectric cable for electrical interface because the device operates with the small electric charge
  • The output obtained from the piezoelectric transducer is low, so the external electronic circuit has to be connected 
Applications of piezoelectric transducer:
  • It is used in a record player
  • It is used in accelerometer
  • It can be used in electronic watches
  • It is used in spark ignition engines
This article also gives some advantages of piezoelectric pressure transducer which are given below:

Advantages of piezoelectric pressure transducer:
  • Rugged construction 
  • Small size
  • Excellent frequency response
  • High output with negligible phase shift
Disadvantages of piezoelectric pressure transducer:
  • Temperature sensitive
  • It can be used for dynamic measurement only
  • Piezoelectric crystals are water soluble hence it has a high humidity environment gets dissolved
There is some application of piezoelectric pressure transducer which is given below:
  • It is used in spark ignition engines
  • It is used for measurement of nonelectrical quantities such as acceleration, vibration dynamic pressure, and sound intensity
  • It is used in ultrasonic, nondestructive test equipment, ultrasonic flow meters, micromotion actuators
