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.
