Abstract

The invention discloses an ultrahigh pressure dynamic pressure sensor that includes casing, sensitive bearing membrane, and strain cylinder. A platform that is set SOI silicon micro solid state pressure resistance chip and circuit board is on the cylinder. The SOI silicon micro solid state pressure resistance chip is connected to the circuit board by gold wire. The guide line on the circuit board penetrates from the bottom of strain cylinder of the hole on the platform. The other end of the casing is set changeable shim that connects to the sensitive pressure bearing membrane. The sensor is simple structure, high testing pressure, good dynamic feature. It can meet the demand in the occasion of powder detonating testing and bore pressure field testing.

Description

technical field [0001] The invention belongs to the field of production and application of pressure sensors, and relates to an ultra-high pressure dynamic pressure sensor. Background technique [0002] The measurement of the explosion pressure wave is of great significance for calculating the explosion-proof device, evaluating the destroying ability of the weapon, and calculating the flight distance and speed of the projectile. The explosion process of explosives is a transient process of ultra-high pressure and high temperature, which requires the sensor to have good dynamic performance and high temperature resistance. For example, when a certain type of explosive explodes, the pressure generated is as high as 10GPa, the temperature is as high as 3000°C, and the duration is at the μs level. The dynamic response of the widely used manganese-copper piezoresistive strain gauge sensor has always been a problem, and this sensor is disposable, with a lif...
