Problems solved by technology

However, sensor packaging also has environmental adaptability issues
For example, the packaged sensor is still too bulky to detect in a small space, the package causes the sensitivity of the sensor to attenuate, the packaging material itself will also cause performance degradation due to the harsh environment, and the package cannot solve the problem of sensor temperature drift, etc.

Abstract

The invention provides an electrode type electric field sensor packaging component comprising a packaging tube shell; an electric field sensor chip which is fixed in the packaging tube shell; a packaging cover which covers the opening of the tube shell so as to form a cavity to accommodate the electric field sensor chip; and a packaging electrode which is arranged at one side away from the cavity of the packaging cover, wherein the packaging electrode is divided into a head end, an intermediate segment and a tail end according to the near-to-distant relationship between the packaging electrode and the packaging cover. The invention also provides an application of the electrode type electric field sensor packaging component. With application of multiple designs of the packaging electrode, the spatial resolution of the electric field sensor can be enhanced, the sensitivity of the sensor can be enhanced and the environmental adaptability of the sensor can be enhanced.

Description

technical field [0001] The invention relates to the technical field of electric field monitoring, in particular to an electric field sensor packaging element, and also relates to monitoring the electric field area to be measured by using the electrode type electric field sensor packaging element. Background technique [0002] Electric field monitoring is of great significance. In the field of meteorology, monitoring the surface and high-altitude atmospheric electric field changes can provide information on the breeding, development and occurrence of lightning, and provide important indicators for lightning early warning, thereby providing important safety guarantees for the launch of missiles and satellites and other aircraft. Forests, scenic spots, power transmission lines, and petrochemical refineries provide early warning information. In the power grid field, monitoring the electric field near transmission lines and substations can accurately obtain AC and DC voltage and...
