Pressure gauges are never connected directly to the live steam line; rather a loop or syphon is interposed as close as possible to the pressure gauge. This is done to

A Avoid the overheating of the tubes & bellows which operate them to minimise error and damage
B Form a seal of water by steam condensate to fill the tube or bellows at the pressure being measured
C Both 'A' & 'B'
D Avoid the static head error introduced by steam entry

Correct Answer: Both 'A' & 'B'
