Lakme Instrument Engineer Interview Questions, Process, and Tips

Power cable tray and instruments cable tray are used to distribute power and instrument cables respectively.

• Power cable tray is designed to support and protect power cables, ensuring safe and efficient power distribution.

• Instruments cable tray is specifically designed to support and protect instrument cables, which carry signals for measurement and control purposes.

• Both cable trays are typically made of metal or non-me...read more

The cable laying for a 50x50 cable tray depends on the specific requirements and types of cables being used.

• The cable tray should be properly sized and designed to accommodate the cables.

• Consider the type and size of cables to be laid, such as power cables, control cables, or communication cables.

• Ensure proper segregation and separation of different types of cables to avoid interference.

• Follow industry standards and gu...read more

Instruments that power AI voltage include sensors, transducers, and signal conditioners.

• Sensors convert physical parameters into electrical signals.

• Transducers convert one form of energy into another.

• Signal conditioners amplify, filter, and convert signals for processing.

• Examples include thermocouples, pressure sensors, and strain gauges.

Instruments do not power voltage.

• Instruments measure voltage or current, but do not generate power.

• Power sources such as batteries or power supplies provide the voltage for instruments to measure.

• Instruments may have internal power sources for their own operation, but this is separate from the voltage being measured.

• Examples of instruments that measure voltage include voltmeters, oscilloscopes, and multimeters.
