Description
Technical field
The present invention relates to thickness measuring instrument sonde configuration technical field, more particularly to a kind of coating thickness detector to pop one's head in.
Background technology
Coating thickness detector can nondestructively measure the thickness and nonmagnetic metal matrix of Non-magnetic Coatings On Magnetic Substrates coating
The thickness of upper non-conductive coating.Coating thickness tester has that measurement error is small, reliability is high, stability is good, the spy such as easy to operate
Point, it is control and ensures the essential detecting instrument of product quality, be widely used in manufacturing industry, metal-processing industry, chemical industry
The detection fields such as industry, commodity inspection, and coating thickness detector probe is then its mostly important part, has influence on measurement efficiency and measurement essence
Degree.According to measuring principle, coating thickness detector probe is generally divided into Magnetic gaugemeter probe, vortex Thicknesser probe, ultrasonic thickness measuring probe.
And what is be most widely used is then Magnetic gaugemeter probe and vortex Thicknesser probe.
Electromagnetic thickness measuring probe is the size for utilizing the magnetic flux for flowing into ferromagnet substrate by non-ferromagnetic coating from gauge head, to survey
Determine coating thickness.The size of corresponding magnetic resistance can also be determined, to represent its coating thickness.Coating is thicker, then magnetic resistance is got over
Greatly, magnetic flux is smaller.Utilize the calibrator of magnetic induction principle, however, it would be possible to have the non-magnetic coating thickness on magnetic conduction matrix.One
As require base material permeability more than 500.If clad material is also magnetic, it is required that and base material permeability difference it is sufficiently large
(such as nickel plating on steel).When the gauge head on soft core around coil is placed on tested sample, instrument exports test electric current or survey automatically
Trial signal.The product of early stage uses pointer header, measures the size of induced electromotive force, and the signal is amplified instruction later by instrument
Coating thickness.Circuit design in recent years introduces the ground new technologies such as frequency stabilization, lock phase, temperature-compensating, and measurement is modulated using magnetic resistance
Signal.Also use the integrated circuit of Patent design, introduce microcomputer, make measurement accuracy and reappearance have increased significantly it is (several
Reach an order of magnitude).Modern magnetic induction calibrator, resolution ratio reach magnetic induction calibrator _ electric eddy current measurement principle _ magnetic attraction
The calibrator of measuring principle and calibrator _ eddy current principle is to 0.1um, it is allowed to which for error up to 1%, range reaches 10mm.Electromagnetic thickness measuring
Probe, which can be applied, comes the accurate skin of paint for measuring steel surface, porcelain, enamel overcoat, plastics, rubber coatings, including nickel chromium triangle
Various non-ferrous metal electrodeposited coatings, and various corrosion-inhibiting coatings that chemical petroleum is unemployed.
Electric eddy current measurement probe is that electromagnetic field is produced in gauge head coil using high frequency ac signal, and gauge head is close to conductor
When, vortex is just formed wherein.Pop one's head in nearer from conducting base, be then vortexed more greatly, reflected umpedance is also bigger.This feedback effect
Amount characterizes the size of distance between gauge head and conducting base, that is, on conducting base non-conductive coating thickness size.By
The coating thickness on non-ferromagnetic metal base material is specially measured in this kind of gauge head, so normally referred to as non magnetic gauge head.It is non magnetic
Gauge head does iron-core coil, such as platinum-nickel alloy or other new materials using high frequency material.Compared with magnetic induction principle, the main distinction
It is gauge head difference, the frequency of signal is different, and the size of signal, Scaling are different.As magnetic induction calibrator, thickness measuring is vortexed
Instrument has also reached resolution ratio 0.1um, it is allowed to error 1%, range 10mm high level.Popped one's head in using electric eddy current measurement, in principle
It is measurable to the electrical insulator coating on all electric conductors, as aerospace craft surface, vehicle, household electrical appliances, aluminum alloy doors and windows and
The paint on other aluminum products surfaces, plastic coating and anode oxide film.Clad material has certain electric conductivity, by calibrating equally
It is measurable, but require that the ratio between both conductances at least differ 3-5 times (such as chromium plating on copper).Although steel substrate is also conduction
Body, but this generic task still measures more suitable using magnetic principles
Existing coating thickness detector is all to use two independent sensor probes, the probe of a magnetic methods, one
The probe of current vortex method, need first to determine basic material before measurement, and measured after installing probe, select and assemble and disassemble
Inconvenience.
