Coating thickness may be very important for waterproof performance, corrosion resistance, aesthetic effect, etc. When testing the coating thickness of underwater pipelines, it is necessary to measure the thickness of the underwater coating, and the Thickness Gauge is required to be waterproof. This article Several Thickness Gauges suitable for measuring the coating thickness of underwater pipelines, ships, and bulkheads are introduced.
Coating Thickness Gauges are generally divided into magnetic induction, eddy current, ultrasonic, mechanical and destructive according to the measurement principle. According to the probe, it is generally divided into one-piece type and probe type. Generally, split probes and mechanical Thickness Gauges are used in underwater measurements.
1. Defelsko PosiTector 6000 coating Thickness Gauge
Underwater measurement can be carried out with the following probes
F (magnetic induction probe) (FS, FRS, FTS) - up to 75 m
N (eddy current probe) (NS, NAS, NRS) - up to 15 m
FN (magnetic induction/eddy current dual function) (FNS, FNRS, FNDS) - up to 15 m
Extended cable lengths are also available for ferrous microprobes (F0S, F45S, F90S) and FKS probes (thick coating) - up to 15 m.
Note: Only the probe can go deep into the water, the main unit cannot be immersed in water, and the micro-probe and FKS probe do not support underwater use .
2. Mechanical Thickness Gauge
The mechanical Thickness Gauge is a kind of Thickness Gauge that does not need power supply and battery. The well-known EPK McCourt coating Thickness Gauge can be used in various environments, suitable for frequent operation and use outdoors, and also There is a balance device, and it is also very suitable underwater. You can choose a suitable Thickness Gauge according to the type of coating you measure underwater.
In addition to the measurement of underwater coating thickness, there are many special measurement scenarios such as high temperature, anti-corrosion, thick coating, explosion-proof, small parts, low headroom, rough surface, and curved surface, which can be communicated with the technical engineers of Beichao Mall.
