Introduction to digital radius dial indicator
Introduction to digital radius dial indicator
- In engineering measurement, arc radius measurement generally uses R gauge plate (also called R gauge) for comparative measurement. Due to the limited specifications of the R gauge sample plate, only the standard arc surface on the R gauge sample plate can be measured. Radius, and it is a comparative measurement, and the actual precise value of the workpiece to be measured cannot be measured. Most other non-standard arcs (specifications not available on the R sample) cannot be accurately measured. In addition, R templates have many specifications. In actual measurement, it takes a long time to select a template with appropriate specifications, and the measurement efficiency is extremely low. This patented product uses capacitive gate sensors, integrated circuits and other high-tech achievements, organically combines machinery, electronic technology, computer technology and sensor technology to develop a new generation of high-tech arc radius measuring instrument. This patented product can measure The actual value of arc surface radius of any specification can be determined with simple operation and fast reading. The digital display radius gauge has the characteristics of small size, convenient reading, and hand-held measurement. It can be used for arc measurement in mechanical parts, wooden molds, construction steel molds, etc. local use.
- This tester adopts a multi-set measuring claw design, and selects suitable span measuring claws for different arc surface radii and measurement accuracy.
- Multiple uses:
1) Digital display dial indicator function;
2) Measurement of the radius of the outer arc surface;
3) Measurement of radius of inner arc surface;
4) Depth measurement;
5) Step measurement;
Features
- A new type of radius measurement tool with high-tech content – a multi-functional digital display radius tester designed using sensor technology, microcomputer technology and integrated circuit technology. It has the characteristics of small size, convenient reading and hand-held measurement. Features, can be used in production sites.
- Using a ball head probe, the error compensation calculation is simple. At the same time, for arc measurement with different radii, the contact point changes, which can extend the service life of the probe and is suitable for curved surface measurement.
- The relationship between measuring range, chord length and accuracy: the lower the accuracy, the larger the measuring range; the longer the chord length, the larger the maximum measuring radius. The minimum measurable radius is half the chord length.
- Use multiple sets of measuring claws to design, and select measuring claws with appropriate spans for different radii and measurement accuracy.
- According to different arcs, five different measuring claws can be used: 10mm, 20mm, 30mm, 60mm, and 100mm.
