本文介绍一种变磁阻压力传感器。它曾成功地用于大气层核爆炸的近区冲击波测量。它的最高最程是100kg/cm~2,对所有量程其响应上升时间都约为1ms。它采用了一根特制的充油导压管,使得传感器可实现地下安装。这样就可在不损失其快速响应特性下经受得起核爆炸的强烈核辐射。传感器曾经历过一系列环境实验和动标定。因此,它能用来在核爆火球附近区域测量冲击波超压的完整波形。本文列了一组核爆炸试验的实测数据。
This article describes a variable reluctance pressure sensor. It has been successfully used for near-area shock wave measurements of atmospheric nuclear explosions. Its highest and highest is 100kg / cm ~ 2, and its response rise time is about 1ms for all ranges. It uses a special oil-filled pressure tube, making the sensor can be installed underground. This can withstand the intense nuclear radiation of a nuclear explosion without losing its fast response. The sensor has undergone a series of environmental experiments and dynamic calibration. Therefore, it can be used to measure the complete waveform of the shock overpressure in the vicinity of the nuclear blast fireball. This article lists the measured data of a group of nuclear explosion tests.
