Iol Chemicals & Pharmaceuticals Engineer Interview Questions and Answers

A 3 wire RTD is a type of resistance temperature detector that uses three wires for accurate temperature measurement.

• A 3 wire RTD is commonly used in industrial applications for temperature sensing.

• It provides more accurate measurements compared to 2 wire RTDs.

• The three wires are used to compensate for the resistance of the connecting wires.

• The resistance of the third wire is equal to the sum of the resistances of the ...read more

Thermocouples are temperature sensors that use the principle of thermoelectric effect.

• Thermocouples are made of two different metals joined together.

• They generate a voltage proportional to the temperature difference between the two junctions.

• Common types include Type K, Type J, Type T, and Type E thermocouples.

• Type K thermocouples are widely used and can measure temperatures up to 1,372°C.

• Type J thermocouples are suita...read more

Conductivity can be measured by using a conductivity meter or by performing a conductivity test.

• Conductivity can be measured by determining the ability of a substance to conduct electric current.

• A conductivity meter is a device that measures the electrical conductivity of a solution.

• The conductivity of a substance is typically measured in siemens per meter (S/m) or microsiemens per centimeter (µS/cm).

• Conductivity tests...read more
