DCS is used for continuous control of complex processes in industries, while PLC is used for discrete control of machinery and equipment.
DCS is typically used in industries such as oil and gas, power plants, and chemical plants for continuous control of processes.
PLC is commonly used in manufacturing industries for discrete control of machinery and equipment.
DCS allows for centralized control of multiple control loops,...
Critical instruments should be calibrated more frequently than non-critical instruments to ensure accuracy and reliability.
Critical instruments should be calibrated at least once a month or as recommended by the manufacturer.
Non-critical instruments can be calibrated less frequently, such as once a year.
Regular calibration ensures accurate measurements and reliable performance of instruments.
Examples: Critical instrume...

Deviation is the amount by which a single measurement differs from a fixed value or average.
Deviation is a measure of how spread out the values in a data set are.
It is calculated by finding the difference between each data point and the mean of the data set.
Positive deviations indicate values above the mean, while negative deviations indicate values below the mean.
Deviation is commonly used in statistics to analyze the
There are two main types of deviations: positive deviations and negative deviations.
Positive deviations occur when actual results exceed expected results.
Negative deviations occur when actual results fall short of expected results.

HVAC efficiency can be calculated by dividing the useful output by the total input.
Calculate the useful output of the HVAC system, such as the amount of heating or cooling provided to the space.
Determine the total input of the HVAC system, including the energy consumed by the system.
Divide the useful output by the total input to get the efficiency percentage.
Efficiency (%) = (Useful Output / Total Input) * 100
For examp...
Filter integrity test is a method to ensure the filter is functioning properly by testing its ability to retain particles of a certain size.
Filter integrity test is performed to verify the effectiveness of a filter in retaining particles of a specific size.
Common methods include bubble point test, diffusion test, pressure hold test, and water intrusion test.
The test results are compared against established acceptance c...
Performing PAO test involves measuring the concentration ratio of a substance in a solution.
Prepare a known concentration of the substance to be tested
Measure the absorbance of the solution at a specific wavelength using a spectrophotometer
Plot a standard curve using known concentrations of the substance
Calculate the concentration of the unknown sample using the standard curve
Concentration ratio can be calculated by di...
ISO 7 particle count refers to the cleanliness level of air in a controlled environment.
ISO 7 classifies air cleanliness based on the number of particles per cubic meter.
Lower particle counts indicate cleaner air and higher particle counts indicate more contamination.
ISO 7 is commonly used in cleanrooms and controlled environments to maintain quality standards.
Example: ISO 7 particle count may be 10,000 particles per c
DX coil is a type of coil used in air conditioning systems to transfer heat between the indoor and outdoor units.
DX coil stands for Direct Expansion coil
It is a key component in air conditioning systems
DX coils are used to transfer heat between the refrigerant and the air being circulated in the system
They are commonly found in split air conditioning systems
