Assistant Engineer Instrumentation Interview Questions and Answers

RTD stands for Resistance Temperature Detector, which is a temperature sensor that operates on the principle of the change in electrical resistance with temperature.

• RTDs are commonly made of platinum, nickel, or copper and have a linear relationship between resistance and temperature.

• To work with an RTD, you need to provide a constant current source to the sensor and measure the voltage drop across it.

• The resistance of the RTD can be converted to temperature using a calibrati...read more
