It is high to the measurement sensitivity of the AT value of tongue tube for the characteristic tester of tongue tube of the present utility model, and test error is little, and result accurately and reliably.Understanding and support accurately can be compared by the correlation parameter information of display device to tongue tube to hold, thus provide the information foundation with practical significance for the use of tongue tube, to improve and to improve the workmanship of its application product further, its method of testing is simple, easy to operate, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the characteristic tester one example structure schematic diagram of the utility model tongue tube.
Embodiment
In order to understand the technical solution of the utility model further, by following examples, the utility model is described in further detail by reference to the accompanying drawings.
To be its magnetic field intensity of use one control the test magnetic field of linear change to put on tested tongue tube by corresponding controller for the characteristic test method of the tongue tube of the present embodiment, and detect corresponding tongue tube in its adhesive and the magnetic field intensity acting on this tongue tube during release by controller, and then calculated the pickup value and release value that obtain tongue tube by corresponding controller.The characteristic tester of the tongue tube of utility model is also included in by after linearly increasing test magnetic field and recording pickup value, then continues to increase and linearly increase test magnetic field one numerical value, the more linear test magnetic field that reduces is until obtain the release value of tongue tube.This method of testing i.e., the magnetic field intensity starting to put on tongue tube during its test release value is greater than magnetic field intensity when making tongue tube adhesive, and the test of the release value being imposes to be greater than to make the magnetic field intensity of tongue tube adhesive as initial test magnetic field; Its test error that the electromagnetic properties differ because of tongue tube can be avoided to produce.Its pickup value and release value can coil voltages (volt), and the electric current (milliampere) or the ampere-turn (AT) that flow through coil represent.
The compensation system adopting a pair test magnetic field to produce interference during test compensates test magnetic field, and its compensation system comprises disturbing magnetic field compensation system in test environment and the compensation system of the ambient humidity that has an impact to test solenoid and/or temperature etc.Its disturbing magnetic field compensation system comprises the earth coil, the stray magnetic field inductive coil that are arranged at (as tested tongue tube side) in test environment, and its humidity and temperature compensator can comprise the humidity and temperature detecting element being connected to controller being placed in test environment.
The characteristic tester of the tongue tube of the present embodiment as shown in Figure 1, comprises controller 1, is connected to LCD display 4 and the power supply 5 of controller 1, and test solenoid 6, disturbing magnetic field compensating coil 7 and temperature compensator 8 etc.Its test solenoid 6, disturbing magnetic field compensating coil 7 and temperature compensator 8 can be placed in tested tongue tube side respectively.
Its controller 1 includes comparison operation circuit 2, switch detection circuit 10 and is connected to the corresponding signal pre-processing circuit 3 of comparison operation circuit 2.Test solenoid 6, disturbing magnetic field compensating coil 7 and temperature compensator 8 are connected to its corresponding pre-process circuit 3.Its corresponding pre-process circuit 3 can carry out shaping to testing accordingly solenoid, disturbing magnetic field compensating coil and temperature compensator etc. and amplify process.
During test, tested tongue tube is fixedly placed in it to test accordingly in solenoid, tested tongue tube is connected to the switch detection circuit of controller, by controller, test solenoid is imposed to the test magnetic field of ascending linear change, when switch detection circuit detects tongue tube adhesive, the pickup value of tongue tube can be obtained by the magnetic field intensity now acting on tongue tube, continue again to increase test magnetic field one numerical value, descending linear reduction afterwards puts on the test magnetic field of tested tongue tube, when switch detection circuit detects that tongue tube discharges, namely same principle obtains the release value of tongue tube.Controller compensates computing by its comparison operation circuit to test solenoid, disturbing magnetic field compensating coil and temperature compensator, eliminates the test error that disturbing factor causes, to obtain test result accurately.
