2.3 Convectron Gauge Tube Installation
The following precautions in the use and installation of the Convectron Gauge tube must be
observed.
x
Observe the precautions at the front of this chapter regarding tube mounting position and high
pressure operation.
x
The gauge tube should be installed with the port oriented vertically downward to ensure that no
system condensates or other liquids collect in the gauge tube.
x
Keep the gauge tube clean. Do not remove the mounting port cover until you are ready to install
the gauge tube.
x
Do not mount the gauge tube in a manner such that deposition of process vapors upon the
internal surfaces of the tube can occur through line-of-sight access to the interior of the gauge
tube.
x
Do not install the gauge tube where high amplitudes of vibration are present. Excessive vibration
will cause forced convection at high pressure giving erroneous readings.
x
Do not bake the tube to temperatures above 150
o
C.
x
Do not install the gauge tubes where they will be exposed to corrosive gases such as mercury
vapor, chlorine, or fluorine, which will attack the gold plated sensor.
x
For greatest accuracy and repeatability the gauge tube should be located in a stable room
temperature environment.
