China resist 2000 ℃ ultra-temperature bludgon the pressure capsule into develop successfully

Ballistic silicon of a kind of resistant 2000 ℃ instant ultra-temperature isolates the high temperature resistant pressure capsule and was developed successfully in Xi'an Communications University precision engineering research institute a few days ago. The expert thinks, this national " 863 " Completion of the plan project, will solve high-temperature environments of domain such as China's Aero-Space, petrochemical industry, auto industry,etc. and make the pressure measurement and high temperature of the instant and strike the invalid technological difficult problem of the sensor effectively, have broken the foreign like product to the monopoly of the market of Chinese sensor, has promoted the integral level and international competitiveness of China this trade, have very high popularization and use value. Routine silicon pressure capsule can only carry on pressure measurement at ℃120, exceed at 120 ℃, the characteristic of the sensor will worsen seriously so that fails.

Routine measurement method and means can't meet pressure measurement under severe environments such as high temperature,etc. and increasingly high measurement accuracy requirement of automatic field, cause the high-temperature pressure capsule products in China to mainly rely on import for a long time. The high temperature resistant pressure capsule that Xi'an Communications University develops can carry on pressure measurement at - 30 ℃- 250 ℃ environment, can finish the pressure measurement of arbitrary quantum range under 1000Mpa, can bear the high temperature of 2000 ℃ instant to strike. Satisfiable high temperature, high pressure, high-frequency and loud and pressure measurement under the severe environment that the instant high temperature is struck,etc., have independent intellectual property rights, have filled in the multiple blanks in this field of China, for promoting the development of Chinese instrument and meter industry, train new growth engines to be significant.

Nagano counting device new pressure capsule is asked the city

The counting device of Nagano introduced the pressure capsule of the new a few days ago, this sensor, through using amorphous metallic glass to make the degree of sensitivity improve by 4 times than before. Metallic glass take shape, use as vibrating plate through penetrate ' Pressure detector) ,Work as the sensory module of pressure through the deposition strain gauge on the vibrating plate.

Because the degree of sensitivity is improved, has not merely braked, or improved the low conditioning type oil engine,etc. car field that fuel injection presses in the accurate oil pressure, and can also be used in the industry field specializing in measuring the air of factory and pressing extensively.

It has been developed for a long time that metallic glass is bright from the well of professor of Japanese metallic material research institute, Nagano counting device has adopted two kinds of metallic glass of zirconium base and nickel base. Compared with stainless steel SUS630 that the vibrating plate of the existing pressure capsule uses, the tensile strength is up to 1.5- 2.5 times of its, but there are only 1/2- 3/4 of its in Young's modulus. Also say and say, metallic glass has the characteristic of high strength, low Young's modulus, serve as pressure capsule, the high strength can improve the pressure tight characteristic, low Young's modulus can improve the degree of sensitivity.

Vibrating plate processing method, original SUS630 adopts and cuts, but new metallic glass penetrates and takes shape. Strain gauge from deposition, it is the thinnest in part that be lasted pressured,there are at 1mm on thickness. Though change after attenuating the degree of sensitivity will be improved, know variation to the linearity of the pressure, so can't be too thin.

Have already developed and can allocate the pressure converter of circuit changing the detected pressure into the electric current in the module of pressure capsule at present, the cost is similar to batch productino products.

Nagano counting device has already examined one of the global four major device suppliers of the field as the pressure device, its occupation rate on the European market of pressure capsule has already been up to 30%, the occupation rate on market of the whole world reaches 20%, the annual sales volume reaches more than 20 billion Japanese yen, NAGANOKEI and NKS have already become and firmlied get the famous brand that global users trust.
