Pressure Gauges And System Indicators

Question 1

Why are pressue gauges and system indicators used?

Answer 1

To enable the system to be monitored to ensure it is running correctly, and to identify faults in the system.

Question 2

Name 5 system indicators in use.

Answer 2

Pressure gauge & vacuum gauge.
Tachometers.
Thermometers.
Flow meters.
Voltage meters.

Question 3

What do nanometers do?

Answer 3

Give a visual representation of pressure and vacuum. If levels are equal, no pressure difference is present.

Question 4

What do tachometers do?

Answer 4

Measures the speed of a moving body.
Normally measures a rotating shaft.
Can show speed of fuel through a system.

Question 5

Answer 5

Fixed brass.
Standard pocket.
Clock/dial face.

Question 6
