novotest Magnetometer NOVOTEST MF-1M

Magnetometer NOVOTEST MF-1M

Magnetometer NOVOTEST MF-1M is designed to control the residual magnetization and study the magnetic heterogeneity of the surface of ferromagnetic products, to control the level of residual magnetization before welding gas and oil pipes, to control the induction of static (DC), alternating (AC) and pulsed magnetic fields generated by various magnetic and electromagnetic devices, such as magnetic particle flaw detectors, magnetic tables and chucks of grinding machines, demagnetizing devices, permanent magnets etc.

Main advantages and functions of Magnetometer NOVOTEST MF-1M:

STATIC (DC) MAGNETIC FIELD

The main purpose of the device is to measure the parameters of a static magnetic field – intensity (induction), as well as its gradient. Using a transverse probe, the user can measure the residual magnetization of the material after magnetic particle inspection, the level of the magnetic component of industrial interference, as well as the magnetic induction of a variety of devices, components and products.

ALTERNATING (AC) AND PULSED MAGNETIC FIELDS

The device allows user to measure the parameters of an alternating magnetic field – values of intensity (induction), as well as the parameters of single pulses of a magnetic field – peak values of intensity (induction).

UNITS OF MEASUREMENT

The magnetometer can display the measured value in units of Ampere/Centimeter (A/cm), Gauss (Gs) and Tesla (mT). That is why sometimes such devices are called Teslameters or Gaussmeter gauges. Also in the device there is a conditional CODE scale, which allows user to assess the change in the magnetic fields of without reference to the scale.

THRESHOLD EXCEEDANCE ALARM FUNCTION

The device has the function of displaying the signal like a graph, which allows the user to monitor the change in the magnetic field strength by scanning the product. Also, in this operating mode, the user can set thresholds for the limiting values of the measured parameters, when the grapf break this threshold the device emits a signal.

VARIOUS PROBES

The device can be equipped with probes for operation in different ranges (± 100G, ± 1000G, ± 3000G), the narrower the range, the higher the measurement accuracy. The instrument is equipped with a transverse probe as standard, but axial probes can be made to order.

DESIGN

The device is sealed and can be used in conditions of high humidity, and the silicone case for the electronic unit makes the device shockproof. Also, the device is not demanding on the temperature of the operating environment, it is possible to use the device in the temperature range from -20 to + 40 ° C.

ARCHIVE OF MEASUREMENTS AND PC SOFTWARE

The device has the ability to create a measurement archive that can be transferred to a PC using special software.

Magnetic Test Samples

Magnetic Test Samples

We produce different types of magnetic test saples, such as: bars, plates, disks with different types of cracks.

The test blocks are used for:

  • quality comparison of different magnetic powders (particle solutions);
  • quality assurance of magnetic powders while working with the testing bench;
  • for quality analysis during the magnetic particle testing, also to check the correct dosing of magnetic powder in automatic testing.

MTU Test Block #3

The MTU test block #3 (is the reference block type 1 according to EN ISO 9934-2) is used to verify the indication sensitivity of magnetic particle crack detection agents.

The test block is a disk with two types (large and small) of natural cracks (in both sides).

The large cracks are sanding cracks and the small cracks are tension cracks.

The test block has been magnetized by use of the hole in the middle of the test block. The analys of the test block is made by comparison of the picture with the results of the test block with fluorescent magnetic powder and ultraviolet lamp.
