Will you calculate the accuracy of the rope displacement sensor in the measurement?
The choice of the rope displacement sensor is important, and the accuracy during the measurement is also very important in the future. Then how do you calculate the accuracy in the measurement? I must know this question Not much, today I will explain it to users who don’t know, for your reference in the future:
1. The measuring element of the rope displacement sensor is a potentiometer, and its accuracy is related to the potentiometer. The potentiometer can be 0.3%, 0.15%, 0.1% and other accuracy, plus the eccentricity of the wire wheel (±0.02mm), if it is a current output, there will be voltage/current conversion errors, and assembly errors. The actual accuracy is difficult to equal the potentiometer . You can add 0.05% to the accuracy of the potentiometer to provide customer parameters based on this.
2. There is another measuring element of the rope displacement sensor-the encoder, whose accuracy is well calculated. Commonly used encoders have 3600 pulses per revolution and 5000 pulses per revolution. If the customer requires a resolution of 0.05mm, if the encoder with 3600 lines (3600 pulses per revolution encoder) is selected, the stroke per revolution should not exceed 180mm , Converted to the diameter of the wire wheel should be (180/3.1415926) -0.7 or 1=56.59 or 56.29mm, the standard wire wheel 56mm can meet customer requirements. Of course, if the customer requires a long stroke and a large reel is needed, an encoder with 5000 lines should be used, and then the resolution should be calculated.
The above mentioned is the accuracy calculation method of the cable displacement sensor. If you still don’t understand, you can consult a technician. The cable displacement sensor, cable encoder, waterproof and explosion-proof displacement sensor produced by Jingliang Electronic Technology have been widely used. Approved by users.
