TEMPERATURE MEASUREMENT TECHNIQUE

Thermistor is a transducer.

Its temperature coefficient is

• Negative

• Positive

• Zero

• None of these

The linear variable differential transformer transducer is

• Inductive transducer

• Non-inductive transducer

• Capacitive transducer

• Resistive transducer

The transducer used for measurement is/are

• Resistance temperature detectors

• Termistors

• Ultrasonic

• All of the above

If at one end, the two wires made of different metals are joined together then a voltage will get produced between the two wires due to difference of temperature between the two ends of wires.

The effect is observed in

• Thermocouples

• Thermistors

• RTD

• Ultrasonic

Which type of temperature sensor requires cold-junction compensation?

• RTD

• Thermistor

• Semiconductor

• Thermocouple

Which metal is most commonly used to make RTD temperature probes

?

• Gold

• Silver

• Aluminium

• Platinum

What device is similar to an RTD but has a negative temperature coefficient?

• Strain gauge

• Thermistor

• Negative-type RTD

• Thermocouple

What device is similar to an RTD but has a negative temperature coefficient?

• Strain gauge

• Thermistor

• Negative-type RTD

• Thermocouple

Temperature sensing can be achieved by the use of

• Thermocouples

• RTDs

• Thermistors

• All of the above

RTDs are typically connected with other fixed resistors

• In a pi configuration

• In a bridge configuration

• And variable resistors

• And capacitors in a filter-type circuit
