▼Main components
The X-ray sensor consists of two parts: the transmitter and the receiver.
The transmitter head mainly includes: transmitter head box, X-ray tube, high voltage power supply, lead sealed container, measuring window film and other components.
The receiving head mainly includes: a receiving head box, an ionization chamber, a DC high-voltage power supply, a signal amplifier circuit board, a signal processing circuit board, a communication circuit board, a measuring window film, etc.
▼Measurement principle
X-rays are generated by loading a high-voltage power supply on the X-ray tube of the transmitter head. X-rays are emitted from the emission window to irradiate the measured medium. Some X-rays are absorbed by the medium material, and some X-rays penetrate the medium to reach the receiving head. The ionization chamber and electronic circuit in the receiving probe receive the weakened rays absorbed by the measured material and convert them into electrical signals proportional to the intensity of the received rays. By establishing a mathematical model between the measured medium and the measured electrical signal, the nonlinear function constant is determined by fitting the relationship between the measured medium and the signal with big data.
In applied measurement, the surface density of the measured medium is calculated using the measurement signal function interpolation method.
▼Technical features
◆ No need to apply for a use permit or environmental protection registration.
◆ Different components of the measured medium can match different ray tube targets to stimulate X-rays of different energy levels.
◆ The lead can seals the radiation source tightly, and the environmental radiation index is reached within a range of 30cm.
◆ 8-15mm measurement gap, shortest ray air path and lowest environmental interference.
◆ The ionization chamber type matches the X-ray energy spectrum, with high sensitivity and wide linearity.
◆ Precision microelectronic circuit, high stability, high signal-to-noise ratio and large dynamic range.
◆ The receiving chamber is heated at a constant temperature and the measuring window is protected from condensation to ensure the stability of the measuring environment parameters.
◆ The measuring window is horizontally blown to prevent dust and clean itself.
◆ Online transmission non-destructive testing.
