Dynomerk Controls Assistant Project Engineer Interview Questions and Answers

RTD measures temperature using resistance while thermocouple uses voltage difference.

• RTD has a linear relationship between resistance and temperature while thermocouple has a non-linear relationship between voltage and temperature.

• RTD is more accurate and stable than thermocouple.

• RTD is suitable for measuring low to medium temperature ranges while thermocouple is suitable for high temperature ranges.

• RTD is more expensi...read more

Thermistors are used when we need to measure temperature changes accurately and quickly.

• Thermistors are resistors that change their resistance with temperature

• They are used in thermostats, temperature sensors, and electronic thermometers

• They are also used in automotive applications to measure engine temperature

• Thermistors are preferred over other temperature sensors because of their high sensitivity and fast response t
