• Classification of Cooking Thermometers 2022-12-07

  For all cooking methods, including grilling, the temperature of the food is the most important indicator. Once we know the temperature, we no longer need to ask the most famous question: "Is it done?" If there is one single piece of advice that can be given to a grill chef, it is to use a good quality digital thermometer. Many bricklayers say that the temperature can be determined by trying the grill by hand, and maybe some people can do it. This is very difficult for most people because everyone responds to heat differently. In 2014, Consumer Reports in the US tested hundreds of chicken breasts from across the US and found that almost all were infected with bacteria -- half of which were antibiotic-resistant. As scary as it sounds, the good news is that these germs can be eliminated. As long as the chicken is cooked to 71.1 degrees Celsius and above, these bacteria can be eliminated. Determining the degree of doneness of food, not relying on a thermometer can only rely on guesswork. Cooking without a good digital thermometer is like diving without a speedometer, punching furniture without a tape measure, and inflating without a barometer. Thermometers are inexpensive, fast, and accurate, and the investment in a few good ones is well worth the money. Nothing will improve your culinary skills faster.

• Classification of liquid level sensors 2022-11-10

  In recent years, with the continuous development of electronic technology and automation, its high-tech has been widely used in various industries, and therefore, the liquid level measurement and control technology has also been greatly improved. In addition, because the functions of the liquid level sensor are becoming more and more perfect, it also provides a huge contribution to many industries, such as the liquid level of various media in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and other industries. Level measurement is now inseparable from the monitoring of the liquid level. Since its development, the importance of liquid level sensors has become increasingly prominent, and even directly affects production and life. Briefly, the liquid level sensor is a liquid level control device with a simple structure and convenient use. It is suitable for continuous detection of liquid level, material level or material level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti-clogging, anti-cold junction and solid powder and granular materials, and can be widely used in various industries. In-process detection control. The common liquid level sensors mainly include capacitive liquid level sensors, floating ball liquid level sensors, ultrasonic liquid level sensors, radar liquid level se

• The new 80ghz radar level gauge will be applied to more complex working conditions 2022-10-31

  80 GHz radar level transmitters, compact instruments with a narrow beam for flexible installations in existing vessel openings – or even non-intrusively through plastic vessels. The transmitters` 80 GHz high frequency delivers robust, reliable measurements even in challenging environments such as those with solids. The custom microchip technology delivers fast response and extremely high sensitivity to detect even the weakest of signals. The transmitters` dependable readings reduce workers` exposure to hazardous situations: no need to climb tanks, lean out over sumps, or crawl into confined spaces to maintain instruments. As well, zero-meter blanking distance allows measurement right up to the sensor, thereby avoiding costly overfilling. And 2 mm accuracy enhances operational safety through precise measurement through the full range of the application. All this robust performance is wrapped in an IP68 submersible housing constructed of corrosion resistant PVDF. As the bandwidth of the radar widens, the resolution of the spectrum increases and the individual targets are indicated by narrower, more accurate peaks: the bandwidth over which the frequency is modulated determines the number of different signals reflected from a target. A 24 GHz radar typically modulates between 24 and 26 GHz and thus has a bandwidth of 2 GHz, while an 80 GHz typically modulates in the range b

• Application of Electromagnetic Flowmeter in Industrial Metallurgical Wastewater Treatment 2022-10-17

  Application of Electromagnetic Flowmeter in Industrial Metallurgical Wastewater Treatment I. With the acceleration of my country's industrialization process, the problem of environmental pollution has become increasingly serious, and the discharge of industrial wastewater has also increased significantly. If these wastewaters are discharged without treatment, they will cause serious pollution to the environment and drinking water. I. Only the lining and electrodes of the sensor part of the intelligent electromagnetic flowmeter are in contact with the liquid to be measured. As long as the electrode and lining materials are reasonably selected, they can be resistant to corrosion and wear. Therefore, it is especially suitable for flow measurement of industrial sewage.

• Principle Analysis and Accuracy Calculation of Radar Liquid Level Meter 2022-10-07

  The antenna of the radar sensor emits electromagnetic wave signals in the form of beams. The emitted waves are reflected on the surface of the material to be measured, and the reflected echo signals are still received by the antenna. Every point in the transmitted and reflected beams is collected by ultrasonic sampling. After the signal is processed by the intelligent processor, the distance between the medium and the probe is obtained and sent to the terminal display for display, alarm, and operation. During the transmission time interval, the antenna system is used as a receiving device. The instrument analyzes and processes the echo signal whose running time is less than one billionth of a second, and analyzes and processes the echo in a very short moment. The radar sensor uses a special time interval adjustment technology to amplify and locate the echo signals per second, and then analyze and process them. Therefore, the radar sensor can analyze and process these amplified echo signals accurately and meticulously within 0.1s, without spending a lot of time analyzing the frequency. The strength of the reflected signal is highly dependent on the dielectric constant of the fluid. Water (ε = 80) is much easier to measure than hydrocarbons (ε <25). The sensors can be tuned to measure either, however. Two operating principles are used: time of flight (TOF) and frequency modulated continuous wave (FMCW). Modern instruments have overcome deficiencies that once plagued the FMCW technology. S
