9.3 Cabling
Each probe requires an interconnecting cable. Cables differ depending on
the probe. The various cables are discussed below under the appropriate
probe type. All of these cable assemblies can be ordered from the factory.
9.3.0a M Series and TF Series Probes
The M and the TF Series probes are connected to the analyzer with a special
GE shielded cable. Probes can be located up to 600 meters (2,000 feet) from
the PM880 (consult the factory for distances up to 1,200 meters). To
measure pressure with a TF probe, the maximum cable length is
approximately 152 meters (500 feet).
9.3.0b Moisture Image Series Probes
The Moisture Image Series probes can be connected to the PM880 with an
unshielded, twisted-pair cable. Each probe may be located up to 915 meters
(3,000 feet) from the analyzer using 22 AWG twisted pair cable. (Consult
the factory for longer cable lengths.)
