Description
Technical Field
The utility model relates to the technical field of electronic calipers, in particular to a multilayer on-board inductance detection device.
Background
An electronic caliper is a common measuring tool used for small-size high-precision measurement, and is called one of three eyes in the industry. It is widely applied to the field of manufacturing industry and daily life. The displacement measurement of the electronic caliper mainly depends on an electronic displacement sensor and a reflector adhered in a groove of a caliper body of the electronic caliper. The inductor on the electronic displacement sensor is a main component, and the inductor is a relatively common circuit element and can be divided into a fixed inductor and an adjustable inductor. The fixed inductor mainly comprises an iron core inductor and a magnetic core inductor, and the adjustable inductor mainly comprises a copper core inductor, a sliding contact adjustable inductor and the like. Different inductances according to their application can be applied in various forms in the circuit. The PCB multi-layer onboard inductor adopts a PCB printing process. The displacement sensor is mainly applied to a displacement sensor as a sensing displacement element. Its quality will directly affect the accuracy of the displacement sensor during displacement measurement and the stability of the signal during displacement measurement. The traditional detection mode is that the inductance is detected one by using a probe, and the efficiency is extremely low.
