How does the pocket roughness meter work
Dec 20, 2018

How does the pocket roughness meter work?


The portable roughness meter is a new generation pocket portable surface roughness meter introduced by our company. It has the characteristics of high measurement accuracy, wide measuring range, easy operation, portability, stable operation, etc. It can be widely used in the detection of various metal and non-metal processing surfaces. The instrument is a pocket-sized instrument integrated with the sensor host. Handheld features are more suitable for use at the production site.


●The shape is designed with aluminum die, which is sturdy and durable, and has remarkable anti-electromagnetic interference capability, which is in line with the new trend of today's design.


● High-speed DSP processor for data processing and calculation, measurement and calculation speed is greatly improved.


● Display liquid crystal adopts popular OLED display, high brightness, no viewing angle, wide temperature, suitable for various occasions.


●Using lithium-ion rechargeable battery, it can work for a long time, no memory effect, can work while charging, charging time is short, battery life is long.


● Use a universal USB interface for charging and communication. It is convenient and quick to use a dedicated charger or USB port of the computer for charging.


● Dot matrix LCD display, rich interface prompt information.


● Real-time monitoring of lithium battery power and display, promptly remind the user to charge and have a charging progress prompt.


●Automatic shutdown function and low-power hardware and software design make the instrument work time is very long, suitable for various field use.


● The sensor probe has a protective door, which effectively protects the sensor probe and ensures the accuracy of the measurement.


Let's take a look at the small series below. How does the pocket-type roughness meter work?


When the sensor is linearly moved along the surface to be tested under the driving of the driving mechanism, the stylus perpendicular to the working surface generates a vertical displacement with the microscopic uneven contour of the working surface, and then the displacement change amount is converted into a power amount by the sensor. The change, the electric signal is amplified, filtered, converted to a digital signal by A/D, and then processed by the DSP to calculate Ra, Rz, Rq, Rt values and display.
