RMG4015The measurement principle of crack depth gauge:

RMG 4015The method of using AC potential difference: Apply an alternating current of known voltage to the probes on both sides of the device.When the probe comes into contact with a workpiece with cracks,There will be a voltage drop,By reducing this voltage drop,The depth of the crack can be measured. But the premise of measurement is:The tested workpiece must have conductive and magnetic properties within the measurement range,And the material properties near the tested crack must be stable,Do not touch the area around the crack during measurement.The width of the crack has almost no effect on the measured values . When measuring oblique cracks, The frequency of the measured current of the instrument decreases along the direction of the crack, Thus extending to the entire workpiece.Calculate the inclination angle of the crack based on the different voltage drops of the left and right electrodes .

The test report can be obtained throughRS232The serial port cable can be printed from a small printer (provided as an attachment), and can also be used to connect the instrumentPCCommunication (through)STATWIN 2002Software). thisPCMust be usedWindowsThe operating system not only provides measurement values, but also offers data management and chart display. In addition, new detection reports or other files can also be created.

Characteristics of RMG4015 crack depth gauge:

New type of crack depth gaugeRMG 4015It can measure iron materials, austenitic steel workpieces, and can also be used for copper, brass, aluminum, and other non-ferrous materials.

The instrument uses alternating current, Utilizing the skin effect of alternating current,Due to the different eddy currents of current on the surface of the workpiece,Thus measuring the size of the crack

Due to the use of low pulse current in the instrument, it is not easy to generate contact sparks during measurement, which will not have any impact on the detection results.

It can measure both ordinary cracks and oblique cracks

Replacing the contact pin without using tools: After wear and tear, remove the contact pin from the guide cylinder of the probe and replace it

Replaceable, gold-plated contact pins

RMG4015Multiple calibration methods are provided: the simplest calibration method is to make a comparative measurement in the area where the workpiece has no cracks. By comparing in this way,Can obtain very accurate measurement results.By comparing and measuring multiple points multiple times,Finally, obtain accurate measurement range and measurement results

The built-in circuit in the probe includes a preamplifier. In this way, the measurement signal can be safely transmitted to the instrument, and in addition, the memory unit is placed inside the probe. It stores independent probe data and material properties.

Integrated Circuit:Pre amplifier and features

The device uses a standard size 5 battery, which is more convenient to carry to the site for use.
