Spain · Catalonia group originated in the nineteenth century, the era of European handicraft workshops prevailed, headquartered in Barcelona, ??Spain, to the 1980s and developed into a set of industry, trade, real estate and other industries as one of the Group's business, industry far sold in Europe, Africa, Asia, South America and other places, has been a century bathroom brands, world-renowned. Ningbo Italian Desi special equipment Technology Co., Ltd. is a wholly owned subsidiary of Catalonia investment group established in August 2005, the site is located in Ningbo, China, European Industrial Park Zone A. Companies adhering to the European industrial technology, specializing in non-ferrous metal casting, polishing, high-precision equipment leak tightness. Our main products are induction furnaces, low pressure die casting machines, multi-axis rough polishing machine, automatic polishing machines, high-precision equipment, leak tightness. Covering six areas, the automotive industry, HVAC industry, pharmaceutical industry, pneumatic / hydraulic components collar industries, water treatment industry, sanitary industries. ITC intelligence leak test differential pressure sensor (DPS) is based on an innovative concept, the use of micro-flow sensors to detect air leaks, (DPS) test method differs from traditional testing methods, based on the mass conservation law, the compensation to be tested also take into account the kind of gas flow in the entire flow rate calculation, at a constant environment, the quality of the inflow rate is equal to the leakage outflow. Smart leak test sensor (DPS) is a design and set-based acceleration laminar flow, pressure and temperature tests in one of the micro flow sensor, DPS is the only sensor on the market exists, the output flow and in the slip flow regime (from vacuum to the high pressure of the pressure change) is proportional to the volume flow, but also with the quality of the translation and the molecular flow region is proportional to the flow rate. DPS built-in processor so that it can not directly test the leakage flow. ITC's micro-flow technology to create a leak test of a new era, it has a test cycle is short, strong anti-interference ambient temperature, and high sensitivity, such as in the past, only the use of helium gas detectors have a little tightness. ITC micro flow sensor leak tester does not require the same leak tester and other "everyday" needs to be calibrated before use, but directly to get accurate test results, make testing easier, more reliable, more user save time, save more manpower * other costs. ITC's "quality of extraction" technology to fully consider the phenomenon of micro-flow of gas and gas expansion characteristics in a vacuum environment. ITC's "quality of extraction" test the sensitivity of the sensor technology intelligence leak test with the use of expensive helium (HMS) is quite sensitive. ITC adaptive test "function enables the test statistics from" learning "experience in testing, dynamic testing test sample, this function can effectively reduce single sample test cycle, so that ITC micro-flow technology test equipment on the market test period the shortest test mode. ITC intelligent sensor DPS leak leak test part of the test system. ITC leak tester can not only run a single test platform, but also to expand into a full set of automated leak testing system.
