Overview
The LANDTEK SRT-6210 Roughness Gauge is a surface roughness inspection instrument used in the production site. It is equipped with a 10mm blue backlit LCD display and can measure four parameters of Ra, Rz, Rq and Rt. Measurement accuracy is not greater than +/- 10%. The instrument adopts the Inductance Measurement principle, the measuring needle is a diamond material with a radius of 5 microns, excellent Hardness, built-in lithium-ion rechargeable battery and has an automatic shutdown function to extend Battery life.
Features
1, can measure Ra, Rz, Rq, Rt four asperity parameters
2. Built-in large-capacity lithium-ion rechargeable battery and charging controller
3. Integrated High Accuracy Inductance Sensor
4. With metric-inch conversion function and automatic shutdown function
5. Data storage and data viewing
6, can be connected to the computer via USB, RS-232 data cable or Bluetooth for data output
Principle
During the SRT-6210 Roughness Gauge measurement, the Sensor is placed on the surface of the workpiece to be measured, and the internal drive mechanism drives the Sensor to slide at constant speed. The built-in sharp stylus senses the surface roughness of the Sensor, which causes the displacement of the stylus, changes the Inductance of the Sensor Inductance coil, and generates an analog signal proportional to the asperity at the output of the phase sensitive rectifier. The signal is amplified and level converted into the data collection system, and the DSP chip performs digital filtering and parameter calculation. The final result is displayed on the LCD.
Applications
Production site surface roughness testing
Steps
1. Place the Sensor on the measured surface of the workpiece
2. Start the instrument, and the internal drive mechanism drives the Sensor to slide along the surface at constant speed
3. Sensor stylus feels asperity and generates displacement signal
4. After the signal is processed, the measurement results are displayed on the LCD display
Notice
* Measurement accuracy not more than +/- 10%, indication variability ≤ 6%
The stylus is made of diamond, with a radius of 5 microns and a force measurement of 4mN.
* Operating temperature range 0~ 50 ℃, Humidity < 80% RH
* Automatic shutdown to extend Battery life
* Support metric-to-inch conversion, can be selected as needed
Data transfer via USB, RS-232 or Bluetooth
