Handheld X-ray fluorescent (XRF) analyzers have the capability to quantify or qualify nearly any element from Magnesium to Uranium, depending on specific instrument configurations. Portable XRF spectrometers allow you to take the battery operated analyzer to the sample rather than bringing the sample into the lab.
XRF stands for X-ray fluorescence. It`s a powerful, nondestructive technique for measuring elemental composition from magnesium (Mg) to uranium (U), from parts per million to 100%. Handheld XRF analyzers are portable devices that can be used on location for immediate, lab-quality results to help you determine the next course of action and where it`s needed.
An analyzer emits X-rays that hit the sample. This causes the elements in the sample to fluoresce and travel back to the analyzer`s X-ray detector. The analyzer counts them and makes mathematical calculations to generate a result.

Explosion-proof ball machine function is more robust
Because the early explosion-proof cameras had the disadvantages of slow speed of the PTZ, low preset position accuracy, and dead angle of monitoring, new types of cameras such as the explosion-proof high-speed ball/hemisphere camera also started to enter the explosion-proof field. According to Changzhou Yuhua Jiang Feng, “The earliest domestic explosion-proof dome camera is the British FV brand, and Changzhou Yuhua’s YHQ15 explosion-proof smart ball can be regarded as the second generation of explosion-proof dome camera in China. From the end of 2007 to the beginning of 2008, the market The appearance of the explosion-proof ball machine introduced at the beginning is relatively close to common common high-speed dome cameras.†The explosion-proof high-speed dome camera recently launched by Changzhou Shenghe has a horizontal rotation speed that can be continuously adjusted from 0.2° to 240°/sec. The highest level in the industry.
Explosion-proof high-speed ball / hemisphere appearance, in addition to preset position, auto-cruise, continuous rotation of the PTZ and other features gradually increased, so that explosion-proof monitoring can also be realized in the field of motion detection, automatic tracking, alarm linkage and other intelligent direction.
About motion detection, automatic tracking. Explosion-proof cameras launched by powerful manufacturers will also attach importance to the motion detection function and may include vibration alarms and other functional modules. Motion detection refers to the detection of the tracking target when it is moving. When the screen changes, for example, someone walks through, and through certain settings, the system will automatically perform corresponding processing, that is, send an alarm signal. Explosion-proof camera tracking function is actually an image analysis function, depending on the speed of the PTZ, accurate positioning, if the explosion-proof camera PTZ speed is slow, inaccurate positioning, you can not automatically track an object. This function is usually set through software accessories, background operation control to achieve. Changzhou Shenghe’s new explosion-proof high-speed dome camera and Lidas Systems’ thermal imaging robots all have optional motion detection and automatic tracking capabilities.
Regarding the alarm function, the self-test alarm of the explosion-proof camera is very important. For example, when the PTZ is locked up or the self-test is not in place during the process of self-inspection, the product can hardly play its practical role. If the explosion-proof camera is used in extreme oil fields and mines in the environment, it may be minus 30 in winter. C. PTZ shafts, etc., may be frozen. Explosion-proof cameras may stop working if they do not self-check. Therefore, the self-test alarm is an important guarantee for the stability of the explosion-proof camera's mechanical performance and smooth operation. Some explosion-proof cameras also have an alarm port. The alarm interface is connected with other alarm devices. When an abnormal situation is encountered, the alarm linkage function can be realized. If the camera lens of the explosion-proof camera is artificially blocked, it will also call the police to ensure that monitoring can proceed smoothly.
In addition to the above three aspects, in order to enhance the environmental adaptability of explosion-proof cameras, it is often necessary to add value-added accessories such as sun shields, heaters, filters, wipers, and fan/semiconductor cooling devices to ensure the stable operation of the equipment and the sharpness of the monitoring screen. . Under strong sunlight, such as in mine mining sites in the desert, the use of sun shields can effectively reduce the temperature of explosion-proof cameras, which can average above 6°C. In the winter or ultra-low temperature conditions, the built-in heater can be automatically heated to ensure that explosion-proof cameras work properly. For example, Changzhou Yuhua's products start automatic heating when the temperature is -10°C. Many products of Changzhou Zoan are less than 1°. C starts heating up and down. Dust can usually be cleaned with a wiper to achieve enhanced camera life, reduced failure rates, and thus ensure clear images. Due to the tightness of the enclosure of the explosion-proof camera itself, the fan/semiconductor refrigeration device can play a role of heat dissipation to some extent. Of course, these value-added accessories can be selected according to customer needs and the actual environment.
In addition, a flameproof intelligent vision sensor consisting of a flameproof camera housing, a built-in lens, a camera, and an intelligent vision server has also become an effective assistant in the field of coal mine monitoring. According to Kaiyu (Group) Cheng Yuxiang, the intelligent vision server embeds a complete intrusion detection and analysis module in VTDTM intelligent vision analysis technology, which can automatically detect various invading people or vehicles. After the zone is set, only the intrusion that meets the specified characteristics will trigger the alarm, while other ineligible intrusions will be ignored. At present, due to the appearance of the explosion-proof zero-illumination black-light night-vision camera, the explosion-proof intelligent vision sensor has a great potential in coal mines.
More robust functions of explosion-proof camera principle analysis
Explosion-proof cameras have already been widely used. At the same time, there are more and more engineers who understand and accept explosion-proof cameras. However, there are still quite a few details that need attention and clarification in the selection and installation of explosion-proof cameras.
