Abstract

The invention discloses a carbon-resistance high-pressure sensor, which is composed of a housing, a diaphragm, a carbon-resistance sensitive element, a filler lead tube and a lead wire, and the carbon-resistance sensitive element is sealed and embedded in the casing through the filler and the diaphragm. In the cavity, the lead tube is arranged in the housing, one end of the lead wire is connected to the carbon resistance sensitive element, and the other end is drawn out from the lead tube; the overall shape of the housing is cylindrical, and the carbon resistance sensitive element is arranged at the front end of the housing. The front end of the housing is provided with connecting threads, the middle part has a protruding platform, and an annular groove is arranged on it, the lead pipe is arranged at the rear of the housing, and the lead wires are drawn out from the rear of the housing. The above-mentioned high-pressure sensor has the advantages of simple structure, reliable performance, and low cost. The main component of the filler is brown corundum, which has high strength and small transmission loss to pressure. It is suitable for dynamic and static high-pressure measurement and has broad application prospects.

Description

technical field [0001] The invention belongs to the field of sensor technology, in particular to a large-range carbon resistance high-pressure sensor. Background technique [0002] In the fields of national economy and national defense construction, especially military production and strategic and tactical weapon development and testing, it is often necessary to measure high pressure. High pressure, especially dynamic high pressure testing, is related to the development of weapons and ammunition, the launch of aerospace vehicles, and the anti-explosion of materials. And engineering protection test, blasting construction, high-pressure synthesis of new materials, material constitutive relationship and other related fields, so it has attracted the attention of scientific researchers from all over the world and has become a long-term research hotspot, and has developed a variety of related measurements Technology, such as electrical measurement (such as the most extensive dynam...
