TMR201 Hand-held Surface Roughness Tester
Introduction
TMR201 Hand-held Surface Roughness Tester is a new generation of Surface Roughness Tester Series. It features high accuracy, wide application, simple operation, portability and stable performance. The tester is widely used in measuring the surface roughness of various metals and non-metals.
Application
1. Machining process control: grinding, turning, milling, honing, polishing, etc.
2. Heavy industry: shipbuilding, aerospace, pipeline, steel plate
3. Aerospace: turbine blades, turbine shafts, wings and other composite materials.
4. Others: printing roller, floor, and glass.
Measuring Principle
By using wear-resistant diamond needle parts and precise motor drive structure, the sensor walks at the absolute linear movement specified by the standard, and walks at the correct horizontal distance.When the low test force tentacles across the wave peak and wave valley, the high precision inductive bridge circuits will detect their vertical displacement through modulation, amplification and phase sensitive detection wave. The sensitivity can up to nanoscale level.The voltage signal corresponding to the roughness is transmitted to a high computing power ARM + DSP processor, using a standardized algorithm to calculate the surface roughness parameters instantly.
