The function of the linear displacement sensor is to convert the volume of linear mechanical displacement into a electrical signal.In order to achieve this effect, the variable resistance skids are usually set on the fixed part of the sensor, and different resistance values ??are measured by the displacement of the sliding film on the sliding rail.The sensor slide rail is connected to a steady -state DC voltage, allowing small currents flowing through Weianpei, the voltage between sliding slices and the beginning of the end, which is directly proportional to the length of the sliding film movement.The sensor can be used as a divisioner to maximize the requirements for the accuracy of the total resistance of the slide rail, because changes caused by temperature changes will not affect the measurement result.
Straight displacement sensor accuracy
First of all, we analyze the requirements of the linear accuracy of the linear accuracy of the straight -line displacement sensor. The specific requirements are: as the displacement movement can output the space to be shifted into a standard linear resistor output (if the voltage is added in the actual application, it becomes a voltage output.Become a current output).The linear accuracy has absolute linear accuracy and relative linear accuracy. It is difficult to ensure that the absolute linear accuracy is very difficult. We generally evaluate the relative linear accuracy. Fortunately, our digital display instrument has the function of "clearing zero".The relative linear accuracy of our assessment has become the actual absolute linear accuracy. Therefore, it will not be explained in the calibration of the product.
Straight displacement sensor installation
However, if the deviation and inclined deviation of the medium and tilt deviations at the same time will affect the stability and service life of the electronic ruler.Further adjustment should be given.The sliders ruler can reduce the adjustment of the neutral work, but the auxiliary growth rod cannot be canceled. Otherwise, it will cause stability and service life due to poor neutrality, and even cause the electronic ruler to fail.After everything is adjusted, tighten the installation screw, and the strength should make the ground resistance less than 1Ω.Use a multimeter 200Ω gear to measure the resistor between the electronic ruler cover and the installation bracket.With a four -wire or shielding line, the ground end of the electronic ruler should be connected. At the same time, the fourth ends or shielding lines are reliable to ground on the electronic control box.
