Metal outer wall roughness tester surface roughness tester NDT120 factory outlets at reasonable prices

Metal outer wall roughness tester surface roughness tester NDT120 factory direct price fair roughness works: using the principle of acupuncture depiction of a surface roughness measuring instrument consists of sensors, actuators, means zero tables, records, and inductive sensors is profiler One of the main components, which works shown in Figure 2, at one end of the spindle is equipped with sensors diamond stylus, the stylus tip radius of curvature r is small, the measurement will take the stylus on the workpiece, the vertical contact with the measured surface using the drive at a constant speed drag sensors. Conventional surface roughness measuring instrument deficiencies following aspects: less (1) measurement parameters, generally only measured Ra, Rz, Ry and other small parameters; lower (2) measurement accuracy, small measuring range, Ra The range of values ??is generally about 0.02-10μm; (3) measurement is not flexible, such as: the length of the selected evaluation, selection filter; output (4) measurements are not intuitive. Several aspects of these shortcomings caused mainly due to: the reliability of the system is not high, the error of the analog signal processing, large and not easy. Purpose: detection of metallic and non-metallic roughness measured parts of the surface, for a variety of machined parts, machinery processing and manufacturing, testing, inspection and other departments, especially for large parts and production lines of the site inspection, and testing and measuring , commodity inspection departments to go out test, will not damage the workpiece. Measurable workpiece: OTHER shaped surface plane, cylindrical surface, conical, bore, groove, surfaces, and (with suitable sensor) unique characteristics: rigorous temperature and humidity test, adapt to high temperature and high humidity environment, especially South humid climates measured values ??are not affected. High precision, stable measurement values, China's leading quality! Users press the "manual" normal operating conditions, the Company products replacement within three months, two years free maintenance (but wearing consumable parts except probe sensor cable), and is responsible for the product life-long maintenance.
