Description

Technical Field

[0001] The utility model relates to the technical field of vibration sensors, in particular to a portable fixed vibration sensor. Background Art

[0002] Sensor materials are an important foundation of sensor technology. With the advancement of material science, people can manufacture various new sensors. For example, temperature sensors can be made from polymer films, optical fibers can be made into various sensors such as pressure, flow, temperature, displacement, etc., and pressure sensors can be made from ceramics. Polymers can adsorb and release water molecules in proportion to the relative humidity of the surrounding environment. By making capacitors with polymer dielectrics and measuring the changes in capacitance, the relative humidity can be obtained. The plasma polymerization polystyrene film temperature sensor made using this principle has the characteristics of wide humidity measurement range, wide temperature range, fast response speed, small size, can be used for humidity measurement in small spaces, and small temperature coefficient. Patent search revealed that the publication number is: CN212007512U, which discloses a portable fixed vibration sensor. The sensor can install the vibration sensor body on the measured pump and motor through a magnetic base, which is convenient for placement. At the same time, the sensor does not require remote power supply to display the detection data, and it also eliminates the wired connection of traditional sensors, making installation more convenient. At the same time, when the detected value exceeds the standard, the built-in alarm can emit a buzzer to alert the operator and prompt that the vibration is too large.

[0003] Publication number: CN212007512U. The disclosed portable fixed vibration sensor uses a magnetic base to fix the vibration sensor during use.

At the same time, the magnetism will affect the sensing accuracy of the vibration sensor, and the vibration sensor cannot be adjusted at an angle, resulting in a small application range of the vibration sensor.
