The main purpose of the pressure sensors is to measure and control pressure in air, gaseous and liquid media. The pressure sensor is a device whose physical parameters are changed in variability depending on the medium, whether steam, water or gas. Directly to the pressure sensor by converting these parameters into an electromagnetic pulse and digital code, which further routed to the output device. For more information see this site: LBS Market. Most pressure sensors have a similar structure. It includes a primary pressure transducer, which in turn consists of a receiver pressure and high-sensitivity element, the secondary signal processing, high housing and output device through which the converted signal is sent on a chain. Typically, the sensors differ from each other to transform the signal. Currently, there is 6 methods: strain gauge, piezoresistive, capacitive, resonant, inductive and ionization.
As implemented by our company piezoresistive pressure sensors used method signal conversion. Piezoresistive technology is based on highly integrated elements of monocrystalline silicon. The choice of silicon is reasonable because it has a fairly high temperature and temporal stability. To measure the pressure in the non-aggressive environments, using the principle Low cost, which is to use sensors as the protection of silicone gel, and without it. If you want to measure pressure in harsh environments, use silicone fluid. In this case, security and accuracy pressure sensor switch is sealed in a metal case, which is divided into two part of the diaphragm made of stainless steel.
Since the signals from most types of sensors are slowly varying, their range is in the very low frequencies. In order to properly convert the signal to digital code, we need to suppress high-frequency part of the spectrum, which consists of the interference and noise information. In this case, the actual use of analog-digital converters slowly varying signals. Such a method often used in the industry. Our site offers the widest range of pressure sensors of various modifications. Each sensor has all the necessary documents certifying that confirm the high quality of the goods. The pressure sensor, the price of which is available for most industrial enterprises are able to provide high accuracy and reliability of measuring the pressure in the range of 25 Pa to 400 Bar. For the correctness and accuracy of measurements of pressure sensors are enclosed in a housing of high strength, which protects the internal electronic control gear from mechanical effects. Widespread use of pressure sensors found in cooling systems, hydraulic systems, pumping stations and industrial plants, where it is necessary to monitor and control the level of pressure gaseous or liquid medium. They are also used for monitoring the pressure in the containers, piping, vehicles, tanks and oil refineries. In case of failure you can always seek a qualified service center to help producers, where you will have all possible assistance and return the performance of the pressure sensor of any type.
Ghost 22 584 states that the hoist – lifting device is a pendant with a manual or motorized. Today, every service station, warehouse and production plant are used in their daily work hand hoist. Depending on preferences, working conditions and the type used by different models: gear chain hoists, lever hoists, wire rope hoists and electric hoists, etc. are allocated (elektrotali) and manual hoists. Electric hoists Electric hoists can be divided into two types – chain and rope. The choice of lifting mechanism depends on the weight of cargo that must move and intensity of use. Tali electric cable today perhaps the most popular in the world of lifting equipment used in companies with high rate of work. In Russia, the technical requirements for cable-talyam stated in GOST 22 584.
Load capacity wire rope hoists are sometimes higher than 100 tons. Payload another variety of electric hoist chain, is no more than 5 tons. The rope used in the first model, a more reliable, easy and cheap traction element than the chain, in which there is always a weak link. That quality makes the traction element model hoists so different in design. Average lifting speed chain hoists within 2 …
5 m / min, and cable – 5 … 12 m / min. Electric hoists are undemanding in operation and are suitable for work at temperatures from -63 to +40 degrees Celsius. Chain hoist is used as auxiliary structures for cantilever-cranes. Elektrotali rope used too and the overhead crane for lifting and transport medium and heavy loads, because the duty on wire rope hoists chain excel. The basis of the assembly in an electric hoist – a block mechanism sotoyaschy of motor, reducer, drum or sprockets, brakes, hooks and lifting element. Drum are only in electric cable talyah, and the star – only to chain elektrotelferah. Tal is equipped with a portable control unit, which enables comfortable control mechanism. Available storage equipment of two types – mobile and stationary. Portable models are moved in the vertical and the horizontal plane. Hand Blocks Tal manual for those companies and industries that have no need for lifting at high altitude and in the fast pace of work. They can be hung on a stationary or mobile cat when there is a need horizontal movement of the loads. Tali ruchnyeshesterennye and lever can primenyatsyadlya lifting and outdoors, and indoors, including in a limited area (trenches, wells). Capacity hoist hand is usually up to 10 tons, in special cases – up to 50 tons (such arrangements are made to order). In the manual gear talyah as heavy-lift element applies round-chain 3 m long or more. In the lifting of the load lever talyah performed by acting on a lever mounted on the hoist. Carrying capacity offered hoists up to 3 tons, lifting height of 1.5 m.
Mining equipment industry has excellent prospect The realization of global economic integration promotes China s industries and enterprises in various fields gradually open up the international market; the mining equipment industry with the most widely used mechanical devices, it is explore the international market successfully and usher in greater development space. In this way, while promoting the development of China s mining equipment industry, the technical level of China s mining equipment is improved. Now, the mining equipment industry in China has been on the right track, all types of mining equipment products have been rooted in the international market, and get a certain degree of competitiveness in the market. Today, the environmental protection industry has been facing the international development, so the development of the mining equipment industry also should tend to environmental-oriented direction; in fact, the traditional large-scale mining machinery in mining operations inevitably impact on the environment, and the mines equipment industry enterprises should pay more attention to improve the level of technology and product reduce resource consumption and pollution of the environment, after all, only the green production model is the key for stable development of the industry. With increasing of foreign economic construction, mining equipment demand is also increasing, which will increase the intensity of competition between the enterprises of the mining equipment industry, it cannot help but to stimulate research and development efforts of the mining equipment in China so that it can stably develop in the fierce competition. At this stage, the mining equipment industry is thought have the most excellent prospects in China. Domestic crusher manufacturersshould continue to improve the technical level of cement plant to strengthen their competitiveness in the vast international mining equipment market and drive the booming of domestic mining equipment industry!
