Overview
LEEB LBTQ904 surface roughness instrument is a new intelligent instrument dedicated to the measurement of surface roughness of machined parts. It integrates microprocessor technology and sensing technology, adopts ultra-small architecture, and is suitable for processing industry, manufacturing, inspection, commodity inspection and other departments, especially for on-site inspection of large workpieces and production lines, and verification. The instrument can measure outer circles, planes, cones and grooves with a length and width greater than 80 × 30mm.
Features
1. Adopt ABS engineering injection molding shell, sturdy and durable, strong anti-electromagnetic interference ability, Appearance is not easy to remove paint.
2. High-speed DSP processor is used for data processing and calculation, and the measurement and operation speed is fast.
3. Adopt 128x32 OLED point array LCD screen, clear display, high luminance, no viewing angle, wide temperature adaptation range.
4. Built-in lithium polymer rechargeable battery, can work for a long time, no Memory effecy, support to work while charging, short charging time, long battery life.
5. Equipped with real-time battery power monitoring and display, low power alarm and charging progress prompt functions.
6. With power saving mode, automatically turn off the screen without operation for 3 consecutive minutes, press any key to wake up, and automatic shutdown function, the working time is super long.
7. Sensor probe is equipped with a protective door to effectively protect the probe and ensure measurement accuracy.
8. High Accuracy Piezoelectric Crystal Sensor for accurate measurement.
9. Adopt miniUSB charging interface, compatible with mobile phone charger or computer charging, easy to use.
Principle
When the Sensor moves along the measured surface at a uniform speed in a straight line under the driving mechanism, the stylus perpendicular to the working surface inside it displaces vertically with the microscopic uneven profile of the working surface. The Sensor converts the displacement change into an electrical signal, which is amplified and filtered, converted into a digital signal through A/D, and then calculated by the DSP processor, and finally obtains and displays the asperity parameter values such as Ra, Rz, Rq, and Rt.
Applications
Processing industry, manufacturing industry, testing, commodity inspection department, large workpiece on-site inspection, production line on-site inspection, out verification
Notice
• Instrument operating temperature is 0 ° C-40 ° C.
• Please use a charger with a specification of DC 5V and 500mAh to charge.
• When measuring, make sure that the length and width of the measured groove are greater than 80 × 30mm.
• Pay attention to protect the Sensor probe and make sure the protective door is closed after use.
• When the instrument prompts low battery, please charge it in time.
