Speed measurement sensor for improving amplitude measurement precision of rotating mechanical equipment

Abstract

The invention discloses a speed measurement sensor for improving amplitude measurement precision of rotating mechanical equipment. The speed measurement sensor comprises a skeleton with a different-diameter hole formed in the middle, wherein an annular groove is formed in the middle part of the skeleton along an external circumference, enameled coils are wound in the annular groove, and a screw column is inserted into the different-diameter hole from the upper end and is in screw-thread fit with the skeleton; two needle insert holes are formed in positions which are not provided with the annular groove at the upper part of the skeleton, two insert needles are respectively arranged in the needle insert holes, and the parts of the two insert needles which are positioned at the outer part of the skeleton are respectively welded with led-out wires; the end heads of the two enameled coils are respectively welded with the parts of the two insert needles positioned in the skeleton, and colloid frames are poured on the outer surfaces of the skeleton and the enameled coils. The speed measurement sensor disclosed by the invention is simple in structure, convenient to process and assemble and stable and accurate in lead-out signals, can be used for improving the amplitude measurement precision, and also has good sealing performance and relatively strong corrosion resistance.

Description

technical field [0001] The invention belongs to a speed measuring device for rotating mechanical equipment, in particular to a speed measuring sensor for improving the accuracy of measuring the amplitude of rotating mechanical equipment. Background technique [0002] The speed sensor is a necessary device for measuring the speed of rotating machinery. From the perspective of economy, the speed sensor must not only be able to measure the speed parameters of rotating machinery, but also be able to measure its amplitude parameters. In terms of vibration measurement, the currently used speed sensor has limited the amplitude of induced electromotive force caused by vibration due to its own structure and other factors, and the measured amplitude data has errors and is not accurate enough. Contents of the invention [0003] The present invention is proposed in order to overcome the shortcomings in the prior art, and its purpose is to provide a speed measuring sensor that improves...
