Analog meter for magnetizing current (Digital optional available).
UA & UAHD Units provide both circular and longitudinal magnetization to locate cracks in all direction. Circular Magnetization
Parts are circularly magnetized by either passing the current through the part or through a central conductor inserted through the part or through a central conductor inserted through a hole in the part. This is done by clamping the part or the conductor between the contact plates. This results in a circular magnetic field in the part under test. The defects which are visible are perpendicular to the field i.e. longitudinal cracks or cracks which deviate from the longitudinal direction by not more than 45 degree. The ammeter read the amount of magnetizing current used. The current is controlled infinitely from 0 to maximum. Longitudinal Magnetization
Longitudinal magnetization is accomplished with the part placed between the contact plates. This magnetic field created formagnetic crack detectors is longitudinal. Detectable defects are transverse to the longitudinal field i.e. transverse cracks and cracks deviating slightly from the transverse direction. A Stepless control circuit is used to regulate the flux density. |  |

 | Magnetic Crack Detectors - Portable We manufacture magnetic crack detectors. These are portable in nature.
Applications:
- The FD portable magnetic particle test units provide an economical, convenient way to inspect wide range of parts for surface and near surface defects. These compact devices supply either Alternating Current or HAlf-Wave D.C Current outputs. Used in conjunction with Flawcheck magnetic particles, both circular and longitudinal surface and near surface irregularities may be quickly detected. After inspection, the parts can be demagnetized.
- The model FD-1000 Series operates on 220 Volts, 1 Phase, & 50 Hz are Portable Series. The rated outputs (througth a part of 3/5 Meter long cables and prods) makes the units suitable for heavy-duty services in weld inspection application during fabrication or repair as well as for maintenance inspection of machinery and equipment.
Description:
- These units are self-contained and are housed in rugged aluminum and steel cases.
- Magnetizing cables, in a wide selection of lengths and prod assemblies are available separately. Controls, indicators, either end output terminals or the remote control plug-in receptacle are located on the front panel for maximum visibility and convenience. The current control is in steps. But at extra cost at customer's option stelesss current control with built in automatic demagnetizing facilities can be incorporated. The ammeters show the true magnetizing current in either the A.C or H.W.D.C Mode operation
Operation:
- These units supply both Alternating current and Half-Wave Direct Current. Either dry or wet magnetic particles are used as indicator
- Operation in A.C mode offers maximum sensitivity and speed in locating surface defects. A.C. operation minimizes background interference, permitting better signal interpretation and thereby, increased defect identification sensitivity.
