Short Period Seismometers
The Short period Seismometers is an integrated, portable short-period digital seismograph developed to meet the needs of mobile seismic observation.
The Short period Seismometers integrates a three-component short-period feedback seismometer and a 24-bit data acquisition system into one compact unit. It features a small size, complete functionality, low power consumption, and light overall weight, making it ideal for applications such as mobile emergency monitoring, reservoir-induced seismic monitoring, and scientific field observations.
Description
The Short period Seismometers is an integrated, portable short-period digital seismograph developed to meet the needs of mobile seismic observation.
The Short period Seismometers integrates a three-component short-period feedback seismometer and a 24-bit data acquisition system into one compact unit. It features a small size, complete functionality, low power consumption, and light overall weight, making it ideal for applications such as mobile emergency monitoring, reservoir-induced seismic monitoring, and scientific field observations.
The digital seismometer consists of three main components: the three-component sensor, the data acquisition system, and the monitoring software. The built-in acquisition system supports three-channel synchronous data collection, performs real-time digital filtering, and provides both minimum-phase and linear-phase FIR filter options for users.
The acquisition system is equipped with an embedded Linux operating system, offering strong data storage and management capabilities as well as data service functions. Through the LAN network interface, it supports continuous real-time data transmission and remote FTP download of data files. It also includes 8GB of internal storage (expandable) for long-term local storage of real-time monitoring data.
