Choosing A Measurement Site; Moisture/Temperature Probe Considerations; Sample System Guidelines - GE PM880 User Manual

M e a s u r e m e n t C o n s i d e r a t i o n s
There are a variety of environmental and installation factors that
can affect measurements. These factors should be discussed with
a GE Infrastructure Sensing applications engineer or field sales
person by the time you receive the PM880. However, if you
decide to add additional measurement sites, this section contains
some basic guidelines for selecting a measurement site and
constructing a sample system. This section includes the
following:

C h o o s i n g a M e a s u r e m e n t S i t e
You should have discussed environmental and installation factors
with a GE Infrastructure Sensing applications engineer or field
sales person by the time you receive the PM880. The equipment
should be suited to the application and installation site.
•
Choose an installation site for the probes and sample systems
that is as close to the process line as possible. Avoid long
lengths of connecting tubing. If long distances are
unavoidable, a fast sampling by-pass loop is recommended.
Do not install any other components, such as filters, ahead of
the probes or sample system unless instructed to do so by GE
Infrastructure Sensing.
•
Observe all normal safety precautions. Use the probes within
their maximum pressure and temperature ratings.
