DRT200 Surface Roughness Tester is a kind of portable measuring equipment that is suitable for the need of various production environment and unfixed measurement, with easy and convenient in operation, comprehensive in function, fast in testing, stable in accuracy and easy to carry; it is capable of evaluating surface textures with a variety of parameters according to various latest national standards and international standards, strictly conforming to international standards; with RS232 data port, the machine can connect to PC and optional mini-printer.
Measuring principle
When measuring roughness on specimen surface, the probe is placed on the surface of the specimen, and then tracing the surface at constant rate. The probe acquires the surface roughness by the sharp stylus inside. The roughness on surface causes displacement of stylus which results in change of inductive value in induction coils, thus generates analogue signal which is in proportion to the tested surface roughness at the output end of phase-sensitive rectifier. This signal enters data collection system after amplification and level conversion. After that, those collected data are processed with digital filtering and parameter calculation by DSP chip and the measuring result can be read on LCD, or printed out through printer or communicated through PC.
