LVDT is an example of

• Inductive transducer

• Resistive transducer

• Capacitive transducer

• Active transducer

capacitive transducer for level measurement works on the principle

• variable distance

• variable dielectric

• variable area

• variable resistance

Expansion of LVDT is

• Linear Variable Differential Transformer
• Linear Variable Direct Transformer
• Linear Variable Displacement Transformer

• Linear Variable Displacement Transducer

when the distance between the plates increases, the capacitance

• Increases
• Decreases
• Remains the same
• Becomes infinite

As the overlapping area increases, capacitance

• Decreases
• Remains the same
• Increases
• Is not affected

Expansion of RTD

• Real Temperature Detector

• Resistive Temperature Detector
• Resistance transducer Detector

• Resistance Temperature Device

Piezoelectric effect means

• The generation of heat in a material when subjected to a magnetic field
• The generation of an electric charge in response to applied mechanical stress
• The generation of light in a material when subjected to a magnetic field
• The generation of sound in a material when subjected to an electric field
