Description
Technical field
The utility model relates to magnetic material fields of measurement, is specifically related to a kind of portable coating thickness detector.
Background technology
Coating thickness detector adopts inductive electromagnetic method to measure the thickness of coating.The probe being positioned at parts surface produces a closed magnetic loop, and along with the change of the distance between probe and ferrimagnet, this magnetic loop, by change in various degree, causes the change of magnetic resistance and probe coil inductance.Utilize this principle can distance accurately between measuring sonde and ferrimagnet, i.e. coating thickness.The end of probe of existing coating thickness detector needs to carry out grafting in use, and long-term plug end of probe not only brings inconvenience to user, also reduces the serviceable life of coating thickness detector.
Utility model content
The purpose of this utility model is to provide a kind of portable coating thickness detector, and housing upper end is provided with Multi-functional probe, does not need to plug end of probe for a long time, easy to use, thicknessmeter long service life.
For achieving the above object, the technical scheme that an embodiment of the present utility model is taked is:
Comprise housing, housing forward end face is provided with keyboard and viewing area, and housing upper end is provided with Multi-functional probe, and Multi-functional probe comprises electromagnetic inductive probe and eddy effect probe; Be provided with the sampling module, power amplifier module, A/D modular converter, signal analyse block and the processor that connect successively in housing, processor connects keyboard and viewing area, and sampling module is provided with dual-sampling circuit, and popping one's head in electromagnetic inductive probe and eddy effect is respectively connected.
Preferably, housing is also provided with temperature sensor, temperature sensor connects temperature compensation module, temperature compensation module connection handling device.
Preferably, housing is provided with USB interface.
Preferably, also comprise power module in housing, power module is provided with electrical isolation module.
The beneficial effect that this portable coating thickness detector produces is: housing upper end is provided with Multi-functional probe, and Multi-functional probe comprises electromagnetic inductive probe and eddy effect probe; Be provided with sampling module in housing, sampling module is provided with dual-sampling circuit, and popping one's head in electromagnetic inductive probe and eddy effect is respectively connected.When thicknessmeter uses, use electromagnetic inductive probe or eddy effect probe by Keyboard Control, do not need to plug end of probe for a long time, easy to use, thicknessmeter long service life.
