Spain · Catalonia Group originated in nineteenth century Europe, the prevalence of age handicraft workshops, 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 companies, industry away sold in Europe, Africa, Asia, South America and other places, with the bathroom brand has been a century, world-renowned. Ningbo Italian Desi special equipment Technology Co., Ltd. is a wholly owned subsidiary of Catalonia Group in August 2005 investment in the establishment, the factory is located in China Ningbo European Industrial Park Zone A. Companies adhering to the European industrial technology, specializing in non-ferrous metal casting, polishing, high-precision hermetic leak detection equipment. The main products are induction furnaces, low pressure casting machines, multi-axis rough polishing machine, automatic polishing machines, high-precision hermetic leak detection equipment. Covering six areas, the automotive industry, HVAC industry, pharmaceutical industry, pneumatic / hydraulic parts from industry, water treatment industry, sanitary industries. ITC Intelligent leak test differential pressure sensor (DPS) based on an innovative concept, the use of micro-flow sensor and air to detect leaks, (DPS) test method differs from traditional testing methods, based on the mass conservation law, the compensation to be tested sample flow is also taken into account in the calculation for the entire flow at a constant environment, the inflow rate equal to the quality of effluent leak. Intelligent leak test sensor (DPS) is a design based on accelerated laminar flow and set flow rate, pressure and temperature tests in one of the micro flow sensor, DPS is the only sensor on the market presence of its output flow and the slip flow regime (from high pressure vacuum to pressure changes) of volumetric flow proportional, but also with the quality of translation and molecular flow region is proportional to the flow rate. DPS processor built so that it can not directly test leakage flow. ITC micro-flow technology to create a leak test of the new era, it has short test period, strong anti-interference ambient temperature, and the like in the past only to use highly sensitive helium 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, so that the test simpler, more reliable, more user-saving time, but also save manpower and other hidden costs. ITC's "quality extraction" technology fully into account the phenomenon of micro-flow of gas and gas expansion characteristics in a vacuum environment. ITC's "quality extraction" intelligent leak test sensitivity test sensor technology with the use of expensive helium (HMS) is quite sensitive. ITC adaptive test "function enables statistical data from the test of" 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 the shortest cycle test way. ITC intelligent leak test part leak sensor DPS test system. ITC leak tester can not only test platform running alone, but also to expand into a full set of automated leak testing system.
