A brief overview of the development of coating thickness gauges
开发日趋智能化回顾涂层测厚仪技术发展的历史沿革，沧州欧谱集中表现为以下技术特征： 电路设计：电子管———晶体管———集成电路———专用芯片L 模块化。 The development of thickness gauges is becoming more and more intelligent. Reviewing the history of the development of coating thickness gauge technology, Cangzhou Oupu concentrated on the following technical features: Circuit design: electron tube --- transistor --- integrated circuit --- special chip L modular . Machine function: single (principle) function type --- with some statistical function type --- double principle universal type --- intelligent type. Probe system: host probe separate type --- host and probe integrated (built-in probe) --- the host is equipped with multi-specification probes (optional replacement).
Practice has proved that the instrument is simple to operate, easy to adjust, intuitive to measure, stable and accurate, and is welcomed by users. At present, the domestic market still has a certain sales volume. Computer Coating Thickness Gauge Type 1 Computer Coating Thickness Gauge, launched in the 20th century and early 1980s, is an upgraded product of domestic magnetic thickness gauge. It has a number of measurement data (average value, maximum value, minimum value, standard deviation, measurement times) statistics function, and the measurement value is directly displayed by the LCD. This instrument has the advantages of simple operation, convenient use, good stability, high measurement accuracy, etc., and is favored by users. BCT220测厚仪 ，其突出的特点是采用内置式探头，在国产测厚仪中率先实现仪器主机与测量探头一体化，标志着我国测厚技术的空前进步。 Digital Coating Thickness Gauge In the 20th century and mid-1990s, China developed a new type of digital coating thickness BCT220 thickness gauge . Its outstanding feature is the use of built-in probes. The integration of measuring probes marks an unprecedented advancement in thickness measurement technology in China.
It has two measurement methods: continuous measurement and single measurement. It has a set of statistical values. It adopts LCD digital display, which can store and calculate statistically. There are three measured values, and it is equipped with computer interface, data deletion, undervoltage prompt, A variety of measurement and control functions, such as error prompts and automatic shutdown, are more suitable for fast non-destructive testing on the spot, and become a best-selling brand of domestic instruments. Metal coating thickness gauge 4500.4200 type metal coating thickness gauge developed by Dr. Nicos Automation Instrument Co., Ltd., Germany, entered the Chinese market in the 19th century and the late 1990s.
It adopts the integrated structure of advanced semiconductor electronic tuning technology and built-in dual probes, taking into account the two testing principles of magnetic method and eddy current method. The built-in probes with independent ruby probes on the front and back sides of the host can be separately Quickly measure the thickness of non-magnetic coatings on magnetic substrates such as steel and the thickness of insulating layers on non-magnetic metal substrates such as aluminum and copper. The measurement range is +:. +++!-Repeatability is *!:; .!, And its units of measurement can be converted to micrometers or mils. The advantages of this instrument are its sturdy structure and easy operation. The series of computer precision paint thickness gauges use the same thickness gauge host, through the preparation of multiple specifications for selection and replacement of measuring probes, Hefei Boyi to expand the range and meet the needs of different measured objects under various environmental conditions, in recent years domestic Significant technological innovation of the outer coating thickness gauge. For example, the EPS31004100 series computer precision coating thickness gauge introduced by the German EPK company in the 19th century and the mid-1990s is not only suitable for coating thickness measurement on steel substrates and non-ferrous substrates, but also through the choice of 3> smart probes Expanded thickness measurement range from a few!-To 3 ++-. Among them, the 23 ++ type has full statistics, prints histograms, and uses computer processing technology to implement computer-controlled automatic measurement functions. It is known as a universal coating thickness gauge.
