I. Introduction

This moveable MT tester is suitable for magnetic particle testing. Inspect parts of various shapes made of ferromagnetic materials. Cracks, slag inclusions and other minor defects caused by casting, forging, quenching, grinding, fatigue and other reasons can be found on the surface and near-surface of the parts.

The equipment can perform AC and DC magnetization and AC automatic demagnetization of parts; it can be used for continuous method and residual magnetism flaw detection; it can be fixed for use or carried to the field for use. With appropriate methods such as strut method or winding method, the special-shaped parts of the parts can be properly magnetized. And can perform segmental flaw detection on large-sized parts.

The circuit adopts the adjustment of the conduction angle of the thyristor to adjust the magnitude of the magnetization and demagnetization currents. The AC magnetization can control the power-off phase and make the residual magnetism stable. The integrated circuit control is adopted to make the equipment work safely and reliably. The equipment has the characteristics of small size, light weight, convenient movement and simple operation.

8-bit MCU is adopted as the controller by this magnetic particles flaw detector, and the continuous regulation of magnetizing current can be realized through the precise collection of the AC zero voltage crossing signal and the signal of current regulation. It has the function of maximum current limit. With the function of phase controlled, the detector is suitable for both continuous technique and residual technique.

The current value is displayed on the analog ammeter or digital ammeter. The prod sets and trigger button are for operating in the narrow space.

The output current is reduced from the initial value to zero automatically when demagnetizing. Non-contact switch is adopted for the equipment.

This detector can be connected to the prod sets (handheld electrode sets) or spiral cable (flexible coil). Also there are some coils or electrodes designed for this equipment to become a simple inspection machine tool as option.
