A length measuring sensor is a device that measures dimensions by irradiating a laser or other light source onto an object to be measured and capturing the amount of light emitted by the object as it shuts off the laser or other light source.
By shaping the laser or other light into a band, the sensor detects whether or not the light has reached the light-receiving part, and accurately measures the dimensions of the part where the light has not reached, thereby performing dimensional measurement.
Since this system uses light from a laser or other source, it has the advantage of non-contact measurement, but it also has the disadvantage of being relatively susceptible to external disturbances.
Length measuring sensors are used to continuously measure the thickness of sheet-like objects such as film, or the outer diameter of long, thin objects with circular cross-sections such as wire. The sensor is placed in a straight line and scanned continuously.
The length measuring sensor can also be used in a variety of applications, such as measuring dimensions in the XY direction by using length measuring sensors in a straight line, or measuring one end face of an object with a large cross-sectional shape by using two or more length measuring sensors.
Length measuring sensors mainly use lasers to measure the dimensions of objects. The laser is irradiated parallel to the measurement axis, and the sensor measures the dimensions by detecting the width of both edges as edges where the laser is blocked. Therefore, the sensor is divided into a light-emitting part that emits a laser and a light-receiving part that reads the emitted laser, and a display part that displays the measured values is also required.
Since the distance from one end to the other end of the area where the laser is blocked by the object to be measured must be accurately read, the laser must be in the shape of a strip or rectangle with a wide width. The light receiving part that reads the laser must be able to continuously read the laser and the part that is not in one section, so CCD line sensors are often used. The scanning interval for reading edges and measuring dimensions depends on the processing speed of the display unit, but scanning can be done at 0.1-second intervals, allowing accurate measurement even if the object to be measured swings slightly.
