WSQ-1型自记水管倾斜仪是浙江省地震局和杭州自动化仪器厂联合研制的定点形变观测仪器。在仪器的研制过程中,对其静态和动态特性进行了仔细地研究和计算,样机安装后,又作了实验测定。静态特性试验的主要内容是测定仪器的灵敏度、非线性度.线性范围(量程)和重复精度等参数。WSQ-1型自记水管倾斜仪测试组在杭州长桥人防山洞试验点的测试结果如下:仪器的灵敏度大于 20毫伏/微米,非线性系数小于0.8％,一次测量范围为±0.9毫米,接力测量范围为±4毫米,重复精度小于0.62毫伏(相当于0.031微米)。动态特性试验的内容是测定该系统的阻尼系数、固有角频率、液面达到平衡所需的时间等。
WSQ-1 self-recorded water pipe inclinometer is a designated point deformation observation instrument jointly developed by Zhejiang Seismological Bureau and Hangzhou Automation Instrument Factory. During the development of the instrument, the static and dynamic characteristics of the instrument were carefully studied and calculated. After the prototype was installed, experiments were made again. The main content of the static characteristic test is the determination of instrument sensitivity, nonlinearity, linear range (range) and repeatability parameters. The test results of the WSQ-1 self-recorded water pipe inclinometer test group at the Hangzhou Civil Air Defense Cave test site are as follows: the sensitivity of the instrument is greater than 20 mV / m, the nonlinear coefficient is less than 0.8%, the measuring range is ± 0.9 mm, Measuring range of ± 4 mm, repeatability less than 0.62 millivolts (equivalent to 0.031 microns). Dynamic characteristics of the test is to determine the damping coefficient of the system, the inherent angular frequency, liquid level to achieve the balance of the time required.
