Online measurement scheme for ovality of outer diameter of pipes and bars
 Product Introduction
The bidirectional CCD caliper uses a green LED parallel light source and a high-speed FPGA circuit to simultaneously measure the diameter of the product from both X and Y directions, indicating the ellipticity of the product. It is widely used for measuring and controlling the outer diameter of various types of pipes, rods, and bars such as plastic pipes, rubber pipes, steel pipes, aluminum pipes, copper pipes, steel wires, and steel bars.
 Measurement principle
The bidirectional caliper is composed of two sets of intersecting optical paths X and Y, which can simultaneously measure the diameter of the measured object from both X and Y directions and calculate the ellipticity of the measured object.

 Functional characteristics and technical parameters
1. Response speed, 1000 times/second
2. The data processor, using FPGA technology, can perform high-speed and high-precision operations.
3. Communication interface, RS485 communication interface, can be connected to computers, PLCs, etc
4. The data parameters can be set to the nominal value and tolerance of the measured object.
5. Control output, alarm output, can be connected to alarm indicator light.
6. Three row digital display, capable of displaying diameters, ellipticity, or average values in both XY directions simultaneously
