Initial Setup
Choosing a Site
You should have discussed environmental and installation factors
with a GE Panametrics 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
Panametrics.
•
Observe all normal safety precautions. Use the probes within
their maximum pressure and temperature ratings.
•
Locate the electronics unit away from high temperatures,
strong electrical transients, mechanical vibrations, corrosive
atmospheres, and any other conditions that could damage or
interfere with the meter operation.
•
Protect the probe cables from excessive physical strain
(bending, pulling, twisting, etc.). In addition, do not subject the
cables to temperatures above 65°C (149°F) or below -50°C
(-58°F).
•
Observe the proper cable restrictions for the probes. You can
locate the Moisture Image Series probe up to 915 meters
(3,000 feet) away from the electronics unit with unshielded
twisted pair cable. The M Series and TF Series probes require
specially shielded cable. You can locate the M and TF probes
up to 600 meters (2,000 feet) from the unit. If you are
measuring pressure with a TF probe, the cable length should
not exceed 152 meters (500 feet).
