在爆炸条件下,质点速度是衡量振动对工程结构、设备、人员破坏的一个重要指标。同时,对荷载研究和进行结构动力分析也是一个很重要的参数。本文介绍的是差动变压器式过阻尼质点速度传感器。通过试验,证明方案是可行的,传感器不需要前置仪器,测试系统简单可靠,成本低,现场使用方便,能满足0～ In the explosive conditions, the particle velocity is a measure of vibration on the engineering structure, equipment, personnel damage is an important indicator. At the same time, load studies and structural dynamics analysis are also important parameters. This article describes the differential transformer over damping particle velocity sensor. The test proves that the scheme is feasible, the sensor does not need pre-instrumentation, the test system is simple and reliable, the cost is low, and the field is convenient to use, which can meet 0 ~
