The roughness meter, also known as surface roughness meter, surface smoothness meter, surface roughness detector, roughness measuring instrument, roughness meter, roughness tester and other names, was first developed and produced abroad before being introduced to China. Currently, the main roughness meter brands on the market include Taylor roughness meter from the UK, Mal roughness meter from Germany, Hommel surface roughness meter from Germany, Sanfeng roughness meter from Japan, Tokyo Precision roughness meter, Tessa roughness meter from Switzerland, and Yigao roughness meter from the UK, all of which are foreign manufacturer brands; The main brands of domestic manufacturers include: Beijing Times Roughness Tester, Hailiang Roughness Tester, Ningbo United, Shanghai Taiming, 304, Wilson, Lantai, etc.

Working principle of roughness meter: The surface roughness measuring instrument using the needle tracing principle consists of a sensor, driver, zero point gauge, recorder, and inductive sensor, which are one of the main components of the contour meter. A diamond contact needle is installed at one end of the sensor measuring rod, and the curvature radius of the contact needle tip isrVery small, when measuring, place the stylus on the workpiece and make vertical contact with the measured surface. Use a driver to drag the sensor at a certain speed. Due to the undulations of the measured surface contour, the touch will move up and down when sliding on the measured surface. This motion causes the magnetic core to move up and down synchronously through the pivot point, resulting in a change in the inductance of the two differential inductance coils surrounding the magnetic core. The coil of the sensor and the measurement circuit are directly connected to a balanced bridge. The change in inductance of the coil causes the bridge to lose balance, so a signal proportional to the displacement of the contact pin is output. After amplification and phase sensitive detection by an electronic device, a signal that can represent the magnitude and direction of the contact pin displacement is obtained. Afterwards, the signal is divided into three paths: one path is applied to the zero pointer to indicate the position of the contact pin, and the other path is input to the DC power amplifier, which amplifies and drives the recorder to record; After being filtered and amplified by the average meter amplifier, the other path enters the integration calculator for integration calculation, and the surface roughness can be directly read out from the indicator meterRaValue.
