Principle
The NDT180 Roughness Gauge uses the principle of displacement differential inductance Sensor for measurement. The natural diamond stylus (90 ° cone angle, tip radius 5 μm) contacts the surface of the workpiece. The stylus force measurement is 4mN, and the guide force measurement is less than 400mN. The sliding speed of the Sensor is adjusted according to the sampling length, for example, Vt = 0.135mm/s when Ir = 0.25. The measurement process includes filtering (such as RC, PC-R C, Gauss, D-P filters), sampling length selection (0.25, 0.8, 2.5mm) and evaluation length calculation (Ln = Ir × n, n = 1~ 5), and the final output asperity parameters and graphics.
Applications
It is suitable for a variety of machined parts, machining manufacturing, testing, commodity inspection and other departments, especially for on-site inspection of large workpieces and production lines, and outgoing verification of testing, Measurement, commodity inspection and other departments
Standards
ISO4287 international standard, ANSI B46.1 American standard, DIN4768 German standard, JIS B601 Japanese standard
Steps
1. Turn on the power supply of the device;
2. Measurement mode and parameters (e.g. sampling length, filter type);
3. Contact the Sensor stylus to the surface of the workpiece;
4. Start the measurement, the device automatically glides and collects data;
5. View measurement results and graphics, which can be operated by touch screen or buttons;
6. Use an embedded printer to print the results, or export the data via USB.
7. After the measurement is completed, the device can automatically sleep or shut down.
Notice
• Ensure that the working environment temperature is -20 ℃~ 40 ℃ and the humidity is less than 90% RH;
During storage and transportation, the temperature should be kept at -40 ° C to 60 ° C and the humidity should be less than 90% RH.
• Avoid excessive force when using diamond contact pins to prevent damage;
• Regularly check the battery level to ensure battery life.
• Avoid violent vibration during measurement process to ensure accuracy;
• The guide head is cemented carbide, pay attention to the smooth surface when sliding;
Make sure the USB connection is stable before data export.
