Shapoorji Pallonji Group Interview Questions and Answers

Calibration procedure for pressure gauge involves comparing the gauge readings with a reference standard.

• Start by selecting a suitable reference standard with a known accuracy.

• Ensure the pressure gauge is clean and in good condition before calibration.

• Connect the pressure gauge to the reference standard using appropriate fittings and tubing.

• Apply a series of known pressures to the reference standard and record the corresponding gauge readings.

• Compare the gauge readings with t...read more

Accuracy refers to how close a measurement is to the true value, while acceptance criteria are predetermined standards for what is considered acceptable.

• Accuracy is a measure of how close a measurement is to the true value, while acceptance criteria are predetermined standards for what is considered acceptable.

• Accuracy is determined by comparing a measurement to a known standard, while acceptance criteria are determined by the requirements of a particular application or indus...read more

Pressure gauge measures pressure of gases or liquids, vacuum gauge measures pressure below atmospheric pressure, compound gauge measures both.

• Pressure gauge measures pressure of gases or liquids

• Vacuum gauge measures pressure below atmospheric pressure

• Compound gauge measures both

• Pressure gauge is used in applications such as hydraulic systems, air compressors, and refrigeration systems

• Vacuum gauge is used in applications such as vacuum pumps, vacuum ovens, and vacuum packaging...read more

Least count is the smallest measurement that can be taken, while resolution is the smallest change that can be detected.

• Least count is determined by the instrument's precision and accuracy

• Resolution is determined by the number of digits displayed on the instrument

• For example, a ruler with a least count of 1 mm can measure up to 1 mm accuracy, while a digital caliper with a resolution of 0.01 mm can detect changes as small as 0.01 mm

RTD measures resistance changes with temperature while thermocouple measures voltage changes with temperature.

• RTD has a linear relationship between resistance and temperature while thermocouple has a non-linear relationship between voltage and temperature.

• RTD is more accurate and stable than thermocouple.

• RTD is suitable for precise temperature measurements while thermocouple is suitable for high-temperature measurements.

• RTD is more expensive than thermocouple.

• Examples of RTD ...read more

Calibration is the process of adjusting and verifying the accuracy of a measuring instrument or tool.

• Calibration ensures that a measuring instrument or tool provides accurate and reliable results.

• It involves comparing the readings of the instrument to a known standard or reference.

• Adjustments are made to the instrument until it provides accurate readings.

• Calibration is important in industries such as manufacturing, aerospace, and healthcare.

• Examples of instruments that requir...read more
