Overview
The AMITTARI AR-132C surface roughness instrument is a Portable precision Roughness Gauge for the measurement of surface roughness of objects with an Accuracy of no more than +/- 15%. The Sensor adopts the Inductance Working Principle of diamond materials, and the Measurement Angles is 90 degrees. The instrument complies with the national standard GB-T6062 and the four standards of ISO, DIN, ANSI and JIS. It is suitable for the measurement of surface roughness of various machined parts on the production site, and can calculate parameters according to selected conditions and display them clearly on the LCD.
Features
1. High Accuracy Inductance Sensor.
2. Multi-Parameter measurement: Ra, Rz.
3. With metric-to-inch conversion function.
4. RC, PC-RC, GAUSS, D-P four filtering methods.
5. Built-in lithium-ion rechargeable battery and charging control circuit, high capacity.
6. Can remember 7 sets of measurement data and Measurement conditions for next viewing or Connectivity processing.
7. There are two ways to shut down: manual shutdown and automatic shutdown after 5 minutes of keyboard operation.
8. Mechatronics design, small size, light weight, easy to use; built-in standard RS232 interface, can communicate with PC.
Principle
When measuring the surface roughness of the workpiece, the Sensor is placed on the surface of the workpiece to be measured, and the internal driving mechanism drives the Sensor to slide along the measured surface at a constant speed. The Sensor senses the asperity through the built-in sharp stylus, and the displacement of the stylus changes the Inductance of the Sensor Inductance coil, and generates an analog signal proportional to the measured surface roughness at the output end 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 result is displayed on the liquid crystal display, and can communicate with the PC to realize Data analysis statistics and printing.
Applications
Production site measurement of surface roughness of various machined parts
Standards
GB-T6062、ISO、DIN、ANSI、JIS
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 measured surface at constant speed.
3. Sensor stylus sense asperity and generate displacement signal.
4. After the signal is processed, the measurement results are displayed on the liquid crystal display.
5. Optional communication with PC for Data analysis and printing.
Notice
* Accuracy of measurement not more than +/- 15%.
* Sensor material is diamond, force measurement is 4mN.
* The sampling length can be 0.25mm, 0.8mm or 2.5mm.
The evaluation length can be selected from 1L to 5L (L is the sampling length).
The drive speed is adjusted according to the sampling length: 0.135mm/s at 0.25mm, 0.5mm/s at 0.8mm, and 1mm/s at 2.5mm.
The drive speed is 1mm/s when returning.
The instrument can be turned off in two ways: manual or automatic (after 5 minutes of keyboard operation).
* Built-in lithium-ion rechargeable battery, pay attention to charging control.
* The data storage capacity is 7 sets of measurement data.
Communication with PC using standard RS232 interface.
