超声波测量 为了跟上其UltraGauge+™超声波壁厚测量系统的需求，LASERLINC公司更新了传感器设备生产线。三个新 设备包括一个带可调传感器的抓斗开口环，一个固定直径的不锈钢环以及一个来自Delrin的用于较大产品的 固定直径环。 目前，超声波测量能力范围为外径0.0508到228毫米(0.002” 到8.9”)，壁厚0.0127 到25.4毫米(0.0005”到1”)， 测量使用的是不同的传感器设备，测量能力取决于所涉及的材料。 LaserLinc公司制造准确且适应性强的非接触式激光/超声波测量系统，用于电线电缆、纤维和管道业外径、 内径、壁厚、偏心度、同心度、凸角以及更多其他的测量。 测量仪通过Total Vu™软件运行——一个基于个人电脑接口的软件——带来高级用户友好型测量/数据处 理。Total Vu为用户提供可配置的易读控制面板内的实时产品制造图、以及运行和趋势图表、图形化横截面 显示和测量。功能包括进程中的偏差检查、缺陷检测、SPC、反馈控制、数据记录、方法和其他可配置报 告。 LaserLinc系统有各种配置和大小，拥有一个激光扫描微米计，两轴和三轴，以及UltraGauge+超声波壁厚测 量装置。扫描仪是小巧型的，测量速度高。分离发射/接收型可为多股应用提供灵活性和精确度，三轴Triton 系列能提供精确的椭圆度测量，而不管产品方位如何。UltraGauge+使壁厚可以在八个位置测得，速度达到 每秒2000多次测量。 所有LaserLinc微米计和UltraGauge+有4年的质保，部件和劳力。事实上在任何情况下，如果微米计需要质 保维修，则临时的替代者会在前夜运到用户处。 Better steels call for better testing IMATEK Ltd is a UK-based manufacturer of materials testing equipment used primarily in the fields of impact testing and polymer melt rheology. The company’s machines are used around the world to test the properties of materials, components and assemblies, and within a wide range of industries including aero- space, polymer processing, automotive, academic research and steel production. The use of higher grade steels in oil and gas pipeline construction is creating the need for a new genera- tion of specialist impact testers. Imatek offers a range of drop weight tear testers (DWTT) for measuring the fracture characteristics of steel specimens according to API recommended practice 5L3, EN 10274 and ASTM-E 436. Steel grades of X120 and specimens of up to 50mm can be accommodated. A major feature of the Imatek range is the instrumentation and analysis software that provides high qual- ity information, both graphical and tabular, for the specimen failure. Whereas historically the DWTT test method has not required instrumentation, more recent research indicates that it is of benefit when testing the tougher x-steels. Instrumentation enables crack initiation and, most importantly, propagation energies for the specimen to be determined, which is considered a better measure of ‘in-use’ performance for these steels. Imatek also offers an integrated high speed video option that greatly enhances understanding of the behav- iour of a specimen as it undergoes impact. Imatek’s integrated high speed video system uses its C3008 data acquisition system to combine signals recorded during a test event together with high speed video imagery, all under the control of the ImpAcqt software. Since the camera and the data acquisition share the same trigger, data points and images can be precisely correlated. A video sequence provides qualitative information about the test event, and the software also allows quanti- tative information to be extracted.
