QUIZ 5

In calibration, it is important that a calibrating instrument should be used as a standard on a reference instrument being tested to see if it gives similar reading.

• TRUE

• FALSE

The term “deadweight” in deadweight pressure calibration refers to the pressure that is coming to balance or zero due to the gradual application of pressure to the piston cylinder.

• TRUE

• FALSE

Mechanical stress refers to the gradual deterioration of measuring devices because of exposure to different working environments or different temperatures.

• TRUE

• FALSE

When the columns of the device are exposed to the atmosphere, the levels of liquid in the limbs are equal and this indicates the atmospheric pressure.

• TRUE

• FALSE

A simple manometer consists of a glass tube having one of its ends connected to a point where pressure is to be measured and the other end remains open to the atmosphere.

• TRUE

• FALSE

A diaphragm pressure gauge measures pressure using a flexible diaphragm and is commonly found in various applications.

• TRUE

• FALSE

A Bourdon tube pressure gauge measures pressure using a straight tube that straightens in response to pressure, displaying the measurement on a dial.

• TRUE

• FALSE

A bellows pressure gauge measures pressure using a collapsible, accordion-like structure called a bellows, which expands or contracts in response to pressure changes, displaying the measurement on a dial or display.

• TRUE

• FALSE

Temperature is an absolute measure of the thermal energy of a system and is independent of the type of thermometer used.

• TRUE

• FALSE

Pyrometers are devices used to measure high temperatures, typically above the range of standard thermocouples or RTDs.

• TRUE

• FALSE
