What is a Length sensor?

A length measurement sensor is a device that irradiates an object to be measured with a laser, etc., and measures the dimensions by capturing the amount of light generated by the object to be measured blocking the laser, etc. By forming a band of light such as a laser, it is detected whether the light reaches the light receiving part or not, and the dimension is measured by accurately measuring the dimensions of the part where the light does not reach. Since it is a system that measures using light such as a laser, it has the advantage of being able to measure without contact, but it also has the disadvantage of being relatively vulnerable to disturbance.

Application of Length sensor

The length measurement sensor is used to continuously measure the thickness of a sheet-like object such as a film and the outer diameter of an elongated object with a circular cross section such as a wire. Since it is possible to continuously scan at minute intervals of 0.1 seconds or less, it is suitable for situations where a long continuous object to be measured is continuously measured without being cut off in the middle. The length measurement sensor can be used in a perpendicular direction to measure the dimensions in the XY direction, and those with a large cross-sectional shape can be used by measuring one end face at a time using two or more length measurement sensors.
