Inductive Sensing Heads
The search coils are made of a special magnetic alloy, laminated and epoxy resin sealed, wound with robust insulated copper wire and encapsulated.
Four different sizes are available from 6mm, 30mm and 45mm, these are supplied as standard. A 55mm and 95mmhead are available as an optional extra.
The Grouser is supplied in a heavy duty leather case carry case with connection cables, clips and a comprehensive operation manual.
The principle of operation is straight forward, inject a small current at a specific frequency, trace only the current flow at that specific frequency, where the current flows to earth is where the fault or faults are.
In practice this is more complex than it would first appear, Grouser has overcome problems such as spillover, inductive coupling, interference, capacitive coupling, spurious noise, etc. etc.
The Grouser has had 20 years of continuous development, to refine this instrument to an easy to use practical tool, most importantly..........
It works !
