416 TSQ 9000 Hardware Manual
A convectron gauge measures and controls the pressure in the foreline that is connected to the

gauge decreases the power going to the turbomolecular pump. The convectron gauge and
foreline adapter are connected to the foreline hose, which is connected to the turbomolecular
pump.
