What are the advantages and disadvantages of piezoelectric transducer?

There are some advantages of piezoelectric transducer which are given below,

• The piezoelectric transducer has good frequency response.
• It is available in desired shape.
• It has rugged construction.
• It has negligible phase shift.
• It is small in size.
• It offer high output that be measured in the electronic circuit.

There are some disadvantages of piezoelectric transducer which are given below,

• The output obtained from the piezoelectric transducers is low, so external electronic circuit has to be connected.
• The piezoelectric transducer is used for dynamic measurement only.
• It has high temperature sensitivity.
• Some crystals are water soluble and get dissolve in high humid environment.
