The invention relates to the technical field of X-ray thickness gauge power supplies and particularly relates to a high-precision reliable power supply for an X-ray thickness gauge. The power supply comprises a power supply shell and a power supply internal module, the power supply internal module comprises a first power supply, a first power supply filter, a second power supply, a second power supply filter, an alarm control unit, a display setting unit and an X-ray receiving module. The first power supply, the first power supply filter, the second power supply, the second power supply filter, the alarm control unit, the display setting unit and the X-ray receiving module are electrically connected in sequence, the first power supply is used for rectifying an input voltage of the X-ray thickness gauge, and the second power supply is used for inverting an output voltage filtered by the first power supply into a second voltage at a high frequency. According to the invention, an amplification link can be added, the stability is improved, the output voltage is adjustable, a protection circuit is added, the power supply is enabled to work safely and reliably, dual voltage stabilizationis more stable, interference-free, high-precision, voltage and current monitoring is realized through dual filtering, and the reliability is high.
Description
technical field [0001] The invention relates to the technical field of power supplies for X-ray thickness gauges, in particular to high-precision and reliable power supplies for X-ray thickness gauges. Background technique [0002] The X-ray thickness gauge uses the characteristics that the X-ray intensity changes and the thickness of the material when the X-ray penetrates the measured material, so as to measure the thickness of the material. It is a non-contact dynamic measuring instrument. However, the existing power supply for X-ray thickness gauges has large volume, high price, short service life and low reliability. In view of this, a high-precision and reliable power supply for X-ray thickness gauges is provided to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a high-precision and reliable power supply for an X-ray thickness gauge to solve the problems raised in the above-mentioned technologies.
