Dr. Reddy's Instrumentation Technician Interview Questions and Answers

There are three main types of temperature: Celsius, Fahrenheit, and Kelvin.

• Celsius is commonly used in most countries and is based on the freezing and boiling points of water.

• Fahrenheit is used in the United States and is based on a scale where 32°F is the freezing point of water and 212°F is the boiling point.

• Kelvin is the scientific standard unit of temperature and is based on absolute zero, the theoretical lowest po

RTD (Resistance Temperature Detector) measures temperature by detecting changes in electrical resistance.

• RTD works on the principle that the resistance of a metal increases with temperature.

• A known current is passed through the RTD sensor and the voltage drop across it is measured.

• The resistance value is then converted into temperature using a calibration curve or equation.

• Common RTD types include platinum, nickel, and...read more
