Overview
Leeb400 pocket surface roughness instrument is a new intelligent instrument for the measurement of surface roughness of machined parts. The instrument integrates microprocessor technology and sensing technology, and adopts ultra-small architecture to complete the acquisition, processing and display of asperity parameters. It is suitable for processing industry, manufacturing, inspection, commodity inspection and other departments. It is especially suitable for on-site inspection of large workpieces and production lines, as well as outgoing verification. It can measure outer circles, planes, cones and grooves with a length and width greater than 80 × 30mm.
Features
1. The shape is designed with a drawn aluminum die, which is sturdy and wear-resistant and has strong resistance to electromagnetic interference.
2. Using high-speed DSP processor, data processing and calculation speed is fast.
3. The display adopts OLED display, high luminance, no viewing angle, wide Temperature range.
4. Using lithium-ion rechargeable battery, can work for a long time, no Memory effecy, support charging while working.
5. Use the universal USB interface for charging and communication, which is convenient and fast.
6. Dot matrix LCD display, rich in interface prompts.
7. Monitor the battery power in real time and display it, with a charging progress prompt.
8. Automatic shutdown function and low-power design, long working hours.
9. Sensor probe is equipped with protective door to protect probe and ensure Measurement accuracy.
Principle
When the sensor moves along the measured surface at a uniform speed in a straight line driven by the driving mechanism, the stylus inside the sensor perpendicular to the working surface is vertically displaced with the microscopic unevenness of the surface, and the displacement change is converted into an electrical signal through the Sensor. After the signal is amplified, filtered and A/D converted, the DSP processor calculates the values of Ra, Rz, Rq and Rt and displays them.
Applications
Processing industry, manufacturing industry, testing, commodity inspection, large workpiece on-site inspection, production line on-site inspection, out verification
Steps
1. Start the instrument and check the battery level.
2. Select measurement parameters (such as Ra, Rz, etc.).
3. Set the sampling length and evaluation length.
4. Align the Sensor probe with the tested surface to ensure that the protective door is open.
5. Drive Sensor along the surface uniform linear motion measurement.
6. Read and record the displayed asperity parameter value.
7. Turn off the instrument or use the automatic shutdown function after the measurement is completed.
Notice
• Operating temperature in the range of 0 ° C to 40 ° C.
• Check Sensor probe and protective door are in good condition before measurement.
• Avoid use in strong electromagnetic interference environments.
• Charge regularly to maintain battery performance, pay attention to the charging progress prompt.
• Ensure that the measured surface is clean and free of oil or impurities during measurement.
• Clean the Sensor Probe and close the protective door in time after use.
• Carry a charger or backup power supply when going out for verification.
