Moisture/Temperature Probe
Considerations
The M Series, TF Series, and Moisture Image Series probes
consist of an aluminum oxide sensor mounted on a connector
head. Standard probe mounts include a protective stainless steel
shield.
The probe sensor materials and housing maximize durability and
insure a minimum of water absorbing surfaces in the vicinity of
the aluminum oxide surface. A sintered stainless steel shield is
used to protect the sensor from high flow rates and particulate
matter. The end cap should not be removed except upon advice
from GE Panametrics.
The sensor has been designed to withstand normal shock and
vibration. You should make sure that the active sensor surface is
never touched or allowed to come into direct contact with foreign
objects, since this may adversely affect performance.
Observing these few simple precautions will result in a long and
useful probe life. GE Panametrics recommends that probe
calibration be checked routinely, at 12-month intervals, or as
recommended by our applications engineers for your particular
application.
The probe will measure the water vapor pressure in its immediate
vicinity; therefore, readings will be influenced by its proximity to
the system walls, materials of construction, and other
environmental factors.The sensor can be operated under vacuum
or pressure, flowing or static conditions.
