  • Product Overview

    MT-1B magnetic particle flaw detector adapts high-capacity lithium battery pack, converse DC to AC through variable-frequency, providing magnetic powder flaw detector with magnetic power supply. With low power consumption, it can continuous work more than four hour after charging. It especially suits for working in the wild and aerial area.

    Function & application

    It is widely used in the industry of aircraft manufacturing, boiler and pressure vessel, electric, oil field, shipbuilding, turbine and combustion engine parts, mine, machinery, standard parts, oil pump, vehicle parts, bridging, chemical, railway, large mechanical components, steel structure equipment etc. It mainly detects the surface detection of forging, quenching, welding, fatigue, for example, irregular workpiece of chain, crankshaft, bearing, high strength bolt, spring, forging, petrochemical pipe, valve, vane, gear, anchor chain, welding seam etc.

    Working Principle

    Put the workpiece into high-intensity magnetic field, connect electric to make it magnetized, if there are flaws (crack,slag) in or near the surface, there will be a leakage around the flaws. Put good quality magnetic powder(usually the magnetic iron oxide powder)on the object, magnetic powder will gather together near the leaked magnetic field, piled up to form visible traces of magnetic powder. In the proper light, we can see the marks and judge the position, size, shape and degree of the flaws.

    Working Conditions

    Operatiom temperature: -10℃~+40℃
    Storage temperature: -20℃~+70℃

    Relative Humidity: ≤80%
    The environment should avoid strong vibration, magnetic interference, corrosive medium and heavy dust.

    Instrument Features

    l With high resolution, high brightness 3.5 inch color LCD display, intelligent interface, can directly display the location, shape, size and degree of the flaws. It has the functions of software management, image processing and recognition, quantitative and nature analysis of the flaw, and PC communication, detection process can be monitored, the results can be traced and meet the requirements of standard operation and management

    l Stationary and portable two types detector, dry and wet technique are available to meet the different needs of different customers

    l High capacity lithium battery makes it portable, solves the drawbacks of traditional, magnetic particle detector relying on 220V. Low power consumption, small volume, alternative charge method, especially suitable for field and high altitude inspection.

    l New power supply mode improves the sensitivity and accuracy of surface and depth detection

    l Build-in industrial high-definition micro camera, real-time record test results, effectively monitor the flaws that we cant see, built in ROM can communicate with computer, the defects and photos can be transferred to PC, output the inspection report in Excel format.

    l The USB port can transfer the data waveform to the U disk to save, print inspection report, realize network management.

    l Adopts electromagnetic yoke power supply technology can realize continuous work, without time limit.

    l Different electromagnetic yokes can meet different requirements. With auto check, indication test functions 

    l The detector is compact, lightweight, easy to carry, can greatly reduce the work intensity of the testing personnel.

    Operating Method and Attentions

    l Connect the line with detector, start the detector, press detection, choose proper polar distance according to the workpiece.

    l When making dry powder detection, put the powder on the workpiece, move the yoke with 40mm/s, make sure they are well connected, observe whether the powder is pile up.

    l When detecting, there must be overlap, the overlap area should less than 25mm, judge the marks correctly.

    l If the pile up is appeared, blow the redundant powder, make the mark clear.

    Instrument Maintenance

    l Use soft cloth to clean the detector.

    l Avoid strong vibration, place in dry area.

    l When not using for a long time, you should charge it every three months to avoid damping the components.

    l Do not press the key overexert or knock it.

    l After turning off the detector for 5s, boot again, do not boot immediately.
