Device for measuring rotating speed of rotatable component based on sensor

A device for measuring rotating speed of a rotatable component based on a sensor mainly comprises the components of: a marking pen, a rotating speed sensor, a contact pressure head and a power quick connector. The device provided by the utility model can test the rotating speed of the component through the rotating speed sensor and wirelessly transmits data to an industrial personal computer. Furthermore the device provided by the utility model can perform the functions of: automatically fixing the component to be measured through the contact pressure head, performing multiple-point floating electrification through the power quick connector and marking through the marking pen. Therefore batch automatic detection for a production line is realized. A modular design is adopted for the whole device, and each operation task is finished by an independent mechanical whole member. The device provided by the utility model has advantages of: simple operation, low cost, high space saving effect, high safety, high reliability, convenient replacement, etc. The device is particularly suitable for detecting rotatable component products on motor vehicles, non-motorized vehicles, ships, etc.
