Question

Give one application each of the following transducer: (i) LVDT (ii) RVDT (iii) Capacitive (iv) Piezoelectric.

Answer 1

Sure! Here’s an application for each of the transducers:

1. **LVDT (Linear Variable Differential Transformer)**: Used in industrial automation for precise linear position measurement, such as in robotic arms.

2. **RVDT (Rotary Variable Differential Transformer)**: Commonly used in aircraft control systems to measure the angular position of control surfaces.

3. **Capacitive Transducer**: Utilized in touchscreens and sensors to detect touch input or proximity in smartphones and tablets.

4. **Piezoelectric Transducer**: Employed in medical ultrasound equipment to generate and receive sound waves for imaging and diagnostics.

Answer 2

Sure! Here’s a brief application for each:

1. **LVDT (Linear Variable Differential Transformer):** Used in aircraft and spacecraft for measuring precise linear displacements, such as in landing gear position sensing.

2. **RVDT (Rotary Variable Differential Transformer):** Commonly employed in automotive systems for measuring the rotational position of components like steering wheels or throttle valves.

3. **Capacitive Transducer:** Utilized in touch screens to detect the location of touch inputs by measuring changes in capacitance.

4. **Piezoelectric Transducer:** Found in microphones to convert sound vibrations into electrical signals.
