composite sensor

Abstract

The invention discloses a composite sensor, which relates to the technical field of sensors. The composite sensor comprises a substrate in a rectangular plate structure; a plurality of nuts are uniformly distributed on the rectangular plate; a plurality of sensors are uniformly distributed on the rectangular plate; a bolt is matched in each nut; one end of the bolt is axially provided with an opening; each of two sides of the opening, located on the nut, is provided with a channel; a limiting piece is matched in the opening; the limiting piece has a cylindrical structure; the circumferential side surface of the limiting piece is radially provided with two opposite rotation shafts; the limiting piece is matched in the channel in the nut through the rotation shaft; and the plurality of sensors comprise a temperature sensor, a humidity sensor and an infrared sensor. through matching the limiting piece on the bolt and arranging the nut on the substrate, mounting of the composite sensor andlimiting after mounting are facilitated; and through arranging the infrared sensor on the substrate, monitoring on a biological invasion condition in a power cabinet by the composite sensor is realized, and the safety of elements in the power cabinet is enhanced.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a composite sensor. Background technique [0002] The composite sensor itself is a combination that can be understood as a whole. In this combination, two or more sensor units that detect different physical quantities are integrated; the signals of these sensor units can be output separately, usually analog signals, and the advanced ones are composed of The processor embedded in the composite is measured and output in accordance with the specified format. The power cabinet refers to the combination of electrical control cabinets that provide power for the normal operation of the entire machine, including contactors, frequency converters, high-voltage cabinets, transformers, etc. [0003] At present, although the existing composite sensors are excellent in the integration of various sensors, they are not easy to install and stable after installation. During the operation of the ...
