Take everyone to understand the method of rotary displacement encoder to detect linear displacement.
Rotary displacement encoder is a photoelectric rotary measuring device. It directly converts the measured angular displacement into a digital signal. The encoder is a way to convert rotary displacement into a A rotary sensor with a series of digital pulse signals. These pulses can be used to control angular displacement. If the encoder is combined with a gear pin or screw screw, it can also be used to measure linear displacement.
1. Use a coupling to directly couple the rotary encoder with the main shaft of the power unit that drives the linear displacement. The small gearbox is coupled to the power unit. Gears that rotate on a straight rack transmit linear displacement information.
2. Obtain the linear displacement information on the sprocket of the transmission chain, and also obtain the linear displacement information on the timing belt of the timing belt wheel.
3. Use a rotary encoder equipped with a magnetic roller to obtain displacement information on the surface of a flat steel material with linear displacement. You can also use a "retractable steel wire assembly" similar to a "steel tape" to connect to the rotary encoder to detect linear displacement information. Another is to use a "retractable wire assembly" with a small torque motor to connect to a rotary encoder to detect linear displacement information.
The above points are the method of detecting linear displacement by the rotary displacement encoder. The displacement encoder is determined by the uniqueness of each position by the mechanical position. It does not need to be memorized, does not need to find a reference point, and does not need to be counted all the time, which greatly improves the efficiency and precision. Electronic Technology mainly produces wire-drawing displacement sensors, wire-drawing displacement sensors, wire-drawing encoders, micro-displacement sensors, wire-drawing electronic rulers and other equipment.
