Summary of lap with ring type absolute encoder

by:HENGXIANG     2020-12-04
Single ring absolute encoder, to measure the optical encoder in rotation of the scribed line, in order to get * coding, when more than 360 degree rotation, code back to the origin, so it doesn't conform to the principle of absolute coding *, the encoder can only be used to rotate 360 degrees within the scope of the measure, known as the single ring absolute encoder. If you want to measure rotation range of more than 360 degrees, will be used more than ring absolute encoder. The principle of encoder manufacturers use watch gear machinery ( The basic law) , when the rotating center yards, gear transmission through another set of encoder, on the basis of the lap coding number of laps to add code, to enlarge the measuring range of the encoder, the absolute encoder is called a coil more absolute encoder, it is also determined by mechanical position coding, each position encoding * don't repeat, without memory. Another advantage is more laps encoder, because of the large measurement range actually use often more rich, so unnecessarily difficult find when installation, will be a middle position) As a starting point, and greatly simplifies the difficulty of installation and debugging. Pull on the rope of the displacement sensor signal output mode can be divided into digital signal output and analog output, digital output type can choose incremental rotary encoder, absolute encoder, the output signal of square wave ABZ signals or gray code, travel can do 10000 mm, the largest maximum linear precision 0. 01%, the biggest resolution according to different configuration can reach 0. 001 mm/pulse. SSI signal display through attachment to the encoder shaft coupling with the hoist drum shaft and pinion shaft coupling, synchronous rotary encoder and the measured axis, the axis of rotation to be measured can be converted to the rotation of the shaft encoder, through a dedicated tester acquisition encoder values so as to accurately measure the displacement of the test piece. A displacement to be measured and achieved the real-time measurement and control purposes. Suitable for all kinds of lifting, the lifting height of the gate of the screw hoist measurement. SSI signal display is by the absolute type rotary encoder, device or automatic cable or other form of coupler, display, controller, transmission cables, RS485 digital communication interface and other components, gate movement through the coupler drive the sensor, can be output with brake corresponding gray code coding signal. Coil more obvious advantages of absolute encoder in terms of the length positioning has been increasingly used in industrial control positioning.
