Tata Power Trading Company Interview Questions and Answers

Q1. Difference between differential pressure transmitter and transducer
Ans. 
Differential pressure transmitters measure pressure differences, while transducers convert physical quantities into signals.
• Differential pressure transmitters measure the difference in pressure between two points, often used in flow measurement.

• Transducers convert one form of energy into another, such as converting pressure into an electrical signal.

• Example of a differential pressure transmitter: Used in HVAC systems t...read more

Q2. How the pressure gauge working
Ans. 
A pressure gauge measures the pressure of gases or liquids in a system, providing critical data for monitoring and control.
• Uses a sensing element (like a diaphragm) that deforms under pressure.

• The deformation is converted into a readable value, often via a dial or digital display.

• Common types include analog gauges (with a needle) and digital gauges (with electronic sensors).

• Applications range from industrial machinery

Q2. Formula of Radiation of the Day.
Ans. 
The formula for radiation of the day is based on the Stefan-Boltzmann law, which states that the total energy radiated per unit surface area of a black body is directly proportional to the fourth power of the body's absolute temperature.
• Radiation of the day is calculated using the Stefan-Boltzmann law: P = σAT^4

• P represents the power radiated per unit area, σ is the Stefan-Boltzmann constant, A is the surface area, and...read more
