MCQ on Classification of Transducers

Que.1 Identify most suitable definition of a transducer.
  1. A transducer is a device that converts energy from one form to another.
  2. Transducer is a device which converts mechanical energy into electrical energy.
  3. A Transducer is a device which converts electrical energy into mechanical energy.
  4. Transducer is a device which converts physical quantity into electrical quantity.

✔ View Answer

Option 1: A transducer is a device that converts energy from one form to another.

Que.2  _________is a self-generating type transducer that can produce an electrical voltage or current output without utilizing any external power source.
  1. A passive transducer
  2. An active transducer
  3. A primary transducer
  4. A secondary transducer

✔ View Answer

Option 2: An active transducer

Que.3 Which of the following pair is an active transducer?
  1. Strain gauge, LVDT
  2. Inductive proximity sensor, Solar cell
  3. thermocouple, LVDT
  4. Thermocouple, solar cell

✔ View Answer

Option 4: Thermocouple, solar cell

Explanation:
Thermocouple is a device which converts teperature into electrical voltage and
Solar cell convers solar energy into electrical energy.
Thus both are self-generating type transducers that is active transducers.

Que.4 The transducer which needs an external power supply for its operation is called________.
  1. Active Transducer
  2. Passive Transducer
  3. Inactive Transducer
  4. Capacitive Transducer

✔ View Answer

Option 2: Passive Transducer

Que.5 Which of the following is not a passive transducer?
  1. LVDT
  2. LDR
  3. Strain gauge
  4. Thermocouple

✔ View Answer

Option 4: Thermocouple

Que.6 Identify the pair of Passive transducer.
  1. LDR (Light Dependent Resistor), Solar cell
  2. Thermistor, Thermocouple
  3. LVDT (Linear Variable Differential Transformer), Strain Gauge
  4. Solar cell, Thermocouple

✔ View Answer

Option 3: LVDT (Linear Variable Differential Transformer), Strain Gauge

Que.7 An electrical transducer _________.
  1. requires external power for conversion of one quantity into other.
  2. does not require external power for conversion of one quantity into other.
  3. converts any quantity to be measured into a usable electrical signal.
  4. converts electrical signals into pressure.

✔ View Answer

Option 3: converts any quantity to be measured into a usable electrical signal.

Explanation:
The function of converting non-electrical quantity into electrical one is accomplished by a device called the electrical transducer.
Basically an electrical transducer is a sensing device by which a physical, mechanical or optical quantity to be measured is transformed directly, with a suitable mechanism, into an electrical signal (current, voltage or frequency).
The production of these signals is based upon electrical effects which may be resistive, inductive, capacitive etc in nature.

Que.8 When the input signal is directly sensed by the transducer and physical phenomenon is converted into the electrical form directly then such a transducer is called
  1. primary transducer
  2. secondary transducer
  3. electrical transducer
  4. active transducer

✔ View Answer

Option 1: primary transducer

Que.9 In case of pressure measurement, bourdon tube is a primary sensor which converts pressure first into displacement, and then the displacement is converted into an output voltage by an LVDT. In this case LVDT is ________.
  1. primary transducer
  2. secondary transducer
  3. electrical transducer
  4. pre-primary transducer

✔ View Answer

Option 2: secondary transducer

Que.10 Transducers, on the basis of nature of output signal, may be classified into
  1. primary and secondary transducers
  2. active and passive transducers
  3. electrical and inverse transducers
  4. analog and digital transducers

✔ View Answer

Option 4: analog and digital transducers

Explanation:
Transducers, on the basis of nature of output signal, may be classified into analog and digital transducers.
Analog transducer converts input signal into output signal, which is a continuous function of time such as thermistor, strain gauge, LVDT, thermo-couple etc.
Digital transducer converts input signal into the output signal of the form of pulse e.g. it gives discrete output.
