Measurement and Temperature Quiz

What is the formula for pressure (P)?

• P = Force (F) - Area (A)

• P = Force (F) + Area (A)

• P = Force (F) / Area (A)

• P = Force (F) * Area (A)

What is the unit of pressure used in the metric system?

• Torr (mmHg)

• Pascals (Pa)

• Atmospheres (atm)

• Pounds per square inch (psi)

What is the principle of operation for a Bourdon tube pressure gauge?

• Relies on the deformation of a flexible diaphragm

• Utilizes the expansion and contraction of a sealed metal bellows

• Measures pressure difference by comparing liquid levels

• Elastic deformation of a curved tube

In which industry are bellows gauges commonly used?

• Aircraft cabin pressure

• Vacuum systems

• Industrial and HVAC systems

• Controlled environments

What is the function of a Differential Pressure (DP) Transmitter?

• Measures the difference in pressure between two points in a system

• Measures the absolute pressure in a system

• Measures the pressure at a single point in a system

• Measures the flow rate of a fluid

What is the principle of operation for a filled system thermometer?

• Relies on the deformation of a flexible diaphragm

• Works based on the principle that substances expand or contract with changes in temperature

• Measures the difference in pressure between two points in a system

• Utilizes the expansion and contraction of a sealed metal bellows

What is the principle of operation for a thermocouple?

• Utilizes the expansion and contraction of a sealed metal bellows

• Operates based on the Seebeck effect, which involves the generation of a voltage across the junction of two different metals when there is a temperature difference

• Measures the difference in pressure between two points in a system

• Works based on the principle of electrical resistance changes with temperature
