有许多不同类型的仪器可用于检测地面运动。宽带地震仪属于一类称为惯性传感器的传感器。相比之下，应变计和全球定位系统 (GPS) 等传感地面运动的方法不被视为惯性传感器。在本文中，讨论了宽带地震仪的工作原理，并将其与无源地震仪的工作原理进行了对比。讨论了选择地震仪的标准。特别关注噪声产生机制，包括传感器内产生的自噪声、环境敏感性和安装相关噪声。
There are many different types of instruments which can be used to detect ground motion. Broadband seismometers belong to a class of sensors called inertial sensors. In contrast, methods of sensing ground motion such as strainmeters and Global Positioning Systems (GPS) are not considered inertial sensors. In this entry the principles of operation of broadband seismometers are discussed and contrasted with those of passive seismometers. The criteria for selecting a seismometer are discussed. Particular attention is paid to noise-generating mechanisms, including self-noise generated within the sensor, environmental sensitivities, and installation-related noise.
