System Components
Instrument
The Level TROLL Instrument is completely sealed and contains no user-serviceable
parts. The instrument includes pressure and temperature sensors, a real-time clock,
microprocessor, sealed lithium battery, data logger, and memory. Options include a
vented or non-vented pressure sensor in a variety of ranges.
RuggedCable System
RuggedCable Systems are custom-built, durable, direct-read cables that include the
following items.
l
Titanium twist-lock connectors for quick, reliable connections to the instrument,
desiccant, and communication cable
l
Metal shield beneath the cable jacket to prevent electrical interferences
l
Kellems grip for secure instrument deployment
l
Small desiccant for vented systems (for storage only)
Non-vented cables are marked with VF, which means vent free.
Vented or Non-Vented Cable
Vented cable is used with vented pressure sensors to produce gauged measurements.
The cable vent tube ensures that atmospheric pressure is applied to the back of the
sensor diaphragm.
Non-vented cable is used with non-vented instruments for absolute measurements.
Compensate absolute measurements by using a BaroTROLL Instrument and Win-Situ
Baro Merge Software.
Vented cable is shipped with a small desiccant to protect against
condensation. Larger desiccants are necessary for deployment.
Jacket Options
Tefzel (vented) or thermoplastic polyurethane (TPU, vented or non-vented)
Customizable Cable Lengths
Cables can be ordered up to 1,219 m (4,000 ft).
Cable Termination
Cables can be ordered with a twist-lock termination (female connector) on both ends
that connect to the instrument, the TROLL Com Communication Device, desiccant, and
