N.C.L. Industries Instrumentation Technician Interview Questions and Answers

RTD stands for Resistance Temperature Detector.

• RTD is a type of temperature sensor that measures temperature by correlating the resistance of the RTD element with temperature.

• It is commonly used in industrial applications where accuracy and stability are important.

• RTDs are made of pure metals or alloys with a known temperature-resistance relationship, such as platinum.

• They provide accurate and reliable temperature meas...read more

RTDs and thermocouples are both temperature sensors, but they differ in terms of principle, accuracy, range, and cost.

• RTD stands for Resistance Temperature Detector, while thermocouple is a temperature sensor based on the Seebeck effect.

• RTDs are more accurate and have a higher temperature range compared to thermocouples.

• RTDs are more expensive than thermocouples.

• RTDs have a linear relationship between resistance and te...read more

An analyser is a device that measures and analyzes the properties of a substance or sample.

• Analyzers are used in various industries such as chemical, pharmaceutical, and food processing.

• They can measure properties such as pH, temperature, pressure, and concentration of various substances.

• Examples of analyzers include gas chromatographs, mass spectrometers, and spectrophotometers.
