Redundant Frequency and Timing Systems
A unique feature of our frequency standards and distribution amplifiers is that the two separate parts of the redundant system are identical and can easily be inter-changed, for maintenance purposes. What we mean by this is that that we don't have a "Master" unit and a "Slave" unit. Whatever unit is powered up first becomes the master unit and the other becomes the slave unit.

Frequency Conversion Rotating Magnetic Fla
MT-2XCF
MITECH MT-2XCF rechargeable frequency conversion rotating magnetic flaw detector is based on principle that the leakage magnetic field can absorb the magnetic powder. Make use of magnetic yoke magnetized the workpiece of ferromagnetic material. If there has defects it will produce leakage magnetic field that will adsorb magnetic powder. We could detect the flaw by observing the density of adsorption magnetic powder. It adopts large capacity lithium battery. By the inverter and the phase shifted signal processor to provide power for the detector, it solves the shortcomings of traditional magnetic particle detector relying on the 220V power supply. It has low power consumption and can continuous work for more than 6 hours. And the battery can be charged when the detector is on and off. Especially suitable for the field testing. It can choose the current frequency according to the flaw depth with unique frequency conversion communication design, that improve the detection sensitivity. It’s widely used in aircraft manufacturing, boiler and pressure vessels and other fields. It is a necessary professional precision instrument of quality control, in-service safety monitoring and life assessment.
