The PosiTector 6000 FNDS probe simultaneously measures the thickness of paint and zinc layers in a composite coating system in a single readout.
Composite coating systems use a combination of two corrosion protection systems – typically painted or powder coated on galvanized steel (thermal, electrical, or zinc-sprayed metal). synthetic corrosion protection due to any individual protection system.
In composite mode, the positector 6000 FNDS uses the principles of magnetic induction (ferrous) and eddy current (non-ferrous) to simultaneously calculate and display individual coating and zinc layer thicknesses. The magnetic induction principle is used to measure the total thickness of the lacquer/zinc layer on a ferrous substrate, while the eddy current Thickness Gauge principle is used to measure the thickness of the paint layer on a non-ferrous zinc layer. The zinc layer thickness is calculated by subtracting the thickness of the paint layer from the total lacquer/zinc layer thickness. The schematic diagram is as follows,

When not available, the gauge is like a traditional ferrous/non-ferrous dual-function gauge (similar to the positector 6000 FNS transducer). It is suitable for measuring non-magnetic properties on steelCoating thicknessThe thickness of the non-conductive coating on a non-ferrous metal substrate.
Positicctor Advanced (serial number 730000+) and color LCD are compatible with the Positicctor standard gage. A simple Thickness Gauge update is required.
