All Greenspan Sensors utilise a specially designed Polyurethane Cable. The cable contains 12 x conductors, 1 x drain
wire, and an internal vent tube. The outer jacket is made from UV stabilized Polyurethane and is suitable for all
external, underwater or harsh environment applications. This common cable construction is utilized for vented and
non-vented sensors and all Greenspan Water Quality Sensors. Cables are generally factory fitted at time of
manufacture in specified lengths. Cables can be joined or repaired in the field providing a waterproof connection can
be maintained. Alternatively, cables can be terminated in waterproof junction boxes where cabling to other devices
or longer cable runs are required.
Specially Manufactured Greenspan Cable with 12 cores and Internal Vent
High chemical resilience and abrasive resistance
Conductor cross section : AWG 24,
Electrical Resistance 9 ohm per 100m (per conductor)
Operating temperature: 85°C (max.),
Bending radius (static) : 6 ,
Bending radius (dynamic) 12.
Max Operating voltage : 250V
Jacket Printing (white colour each meter)
Conductor colour codes : green, yellow, white, black, brown,
turquoise, violet, pink, red, blue, grey
Tensile Strength is sufficient to self-suspend the Greenspan Sensor to depths of 300m.
Long term creep due to temperature effects or tensile loading is negligible.
The moulded cable is fitted to the sensor using a double o ring seal and located using 2 x grub screws. The length of
the cable is not critical to the long term calibration and operation of the sensor (provided the electrical requirements
such as minimum supply voltage are maintained).
