ArcelorMittal Manager Instrumentation Interview Questions and Answers

A thermocouple is a temperature sensor that consists of two different metals joined together at one end.

• It generates a voltage proportional to the temperature difference between the two junctions.

• It is commonly used in industrial and scientific applications to measure temperature.

• Different types of thermocouples are available, each with its own temperature range and accuracy.

• Examples of thermocouple types include K, J,...read more

Yes, there are standards governing types of thermocouple.

• The International Electrotechnical Commission (IEC) and the American National Standards Institute (ANSI) have established standards for thermocouples.

• These standards define the types of thermocouples, their temperature ranges, and their accuracy.

• Examples of thermocouple types include Type J, Type K, Type T, and Type E.

• Each type has a different combination of meta...read more

Straight lengths are important in installing vortex orifice devices to ensure accurate flow measurement.

• Straight lengths help to stabilize the flow profile before it reaches the device

• They prevent turbulence and eddies that can affect the accuracy of the measurement

• The length required depends on the type of device and the flow conditions

• For example, a vortex flow meter may require 10 diameters of straight pipe upstream...read more
