Transducer Cable to NJC-80 Sig.Processor
x The Transducer cable must be installed/laid in a way to allow removal in case of
service or replacement of a defective Transducer.
x Installation on cable trays or ladders should assure that the cable is accessible and
not strapped together with other permanently installed cables.
x The cable must be separated at least 0.5 m from any other high power/frequency
cable as well as avoid crossing such cables.
x Whenever installation conditions require use of conduit (e.g. pipe through water
filled tank, etc.) the internal diameter should be adequate to enable easy cable
traction/retraction. TRU cable diameter is approximately 21 mm, thus a pipe inner
diameter of 50 mm (~2 inches) is recommended or never less than 38 mm (~1.5
inch) much depending on number of bends on the conduit.
x Minimize the number of pipe bends as well as assure that the bend radius is never
less than 0.5 m. Keep pipe as straight as possible.
x The cable bend radius shall never be less than 200 mm.
Never cut the cable! Warranty is void if cable is cut or violated.
x Excessive cable length.shall be coiled both close to NJC-80 as well as a service coil
