High-precision anti-corrosion type flow velocity measurement sensor

Abstract

The invention discloses a high-precision anti-corrosion flow velocity measurement sensor, which comprises a protection shell for storage, a detection structure arranged in the protection shell and a box body for displaying data, and is characterized in that the detection structure is strip-shaped and is integrally inserted into the protection shell, and the detection structure is connected with the box body through a transmission data line; the protection shell is cylindrical and long-strip-shaped, a conical part is arranged at the left end of the protection shell, a sealing gasket disc is connected to the right end of the protection shell, the sealing gasket disc is cylindrical, a plurality of through holes are evenly formed in the outer end of the sealing gasket disc, and a plurality oflong-strip-shaped flow guide strips are arranged on the circumferential face of the protection shell at equal intervals. A fastening structure is arranged in the middle of the protection shell in a sleeving manner; the fastening structure comprises a shaft sleeve, and the shaft sleeve is integrally arranged outside the protection shell in a sleeving mode and tightly attached to the outer wall of the protection shell. By additionally arranging the protection shell, the sensor for internal detection can be protected, corrosion is prevented, meanwhile, quick fixing is facilitated, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a high-precision anti-corrosion flow velocity measurement sensor. Background technique [0002] A sensor (English name: transducer / sensor) is a detection device that can feel the measured information, and can transform the sensed information into an electrical signal or other required form of information output according to a certain rule, so as to meet the information requirements. transmission, processing, storage, display, recording and control requirements. The characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systemization, and networking. It is the first link to realize automatic detection and automatic control. [0003] At present, there are mainly pitot tubes, hot wire (or hot film) anemometers, laser Doppler current meters, and particle image velocimeters to measure the dynamic velocity of water flow. Other methods are evo...

Problems solved by technology

[0006] Aiming at the deficiencies of the existing technology, the present invention provides a high-precision anti-corrosion flow velocity measurement sensor, which solves the problem that: the existing flow velocity sensors are often measured in different environments, because the shell of the sensor is in contact with the measurement gas or liquid for a long time Corrosion occurs, and at the same time, most of the traditional sensors are placed inside the pipeline, lacking a corresponding simple fixing structure, difficult to disassemble and install, and extremely inconvenient to use
