Section 2: Components & FeaturesCablesSeveral basic cable types are used in the MP <strong>TROLL</strong> <strong>9500</strong> system:MP <strong>TROLL</strong> <strong>9500</strong>RuggedCableTwist-Lock ConnectorSealed Battery Compartment• RuggedCable, TPU-jacketed (Thermoplastic PolyUrethane)• vented or non-vented• Halogen-Free vented or non-vented (LSZH-rated, lowsmoke zero halide)Vented cable is recommended for applications whereaccurate barometric pressure measurement is required—forexample when calibrating dissolved oxygen, or formeasuring DO in percent saturation.• Vented Tefzel®* cable• Stainless steel suspension wire for use when cable venting is notrequired (e.g., with an absolute pressure sensor)• Communication cables for programming the device/downloadingthe logged dataRuggedCableCable includes conductors for power and communication signals, astrength member, and a Kellems ® grip to anchor the MP <strong>TROLL</strong> <strong>9500</strong>securely. Available in standard and custom lengths.Uphole and downhole ends are identical bayonet-typeTwist-Lock connectors that mate with the <strong>TROLL</strong> <strong>9500</strong>body, <strong>TROLL</strong> Com communication cable, desiccants, andother accessories.Sealed BodyStainless steel Restrictor —provides generous openings forcirculation of environmental water,unscrews for installation/removal ofsensorsVented cable is designed for use with vented pressure/level sensors (gauged measure ments). The cable venttube insures that atmospheric pressure is the referencepressure applied to the pressure sensor diaphragm.Vented cable also enables proper functioning of the internalbarometric pressure sensor, and improves dissolvedoxygen readings.Non-vented cable may be used with non-vented pressure/level sensors (absolute measurements), or instrumentswithout a pressure sensor.Acetal Nose Cone minimizes sedimentbuildup and protects the frontend from bottoming out on a hardsurface; removable for installation ofoptional accessories* FEP = fluorinated ethylene propylene, the generic equivalent of DuPont Teflon®.<strong>TROLL</strong> <strong>9500</strong> Operator’s <strong>Manual</strong>6 0095110 rev. 007 01/09
