SmartSolo IGU-BD3C-5 broadband seismic data acquisition unit contains a set of electromagnetic conversion system, which generates millivolt signals proportional to the vibration intensity of the measured medium (usually soil).It adopts the current international popular and reliable electronic spread spectrum technology, so that the frequency range can reach 0.2hz-150hz, and has the super strong ability to detect greater depth.The sensor is adjusted by the bottom leveling screw and the bubble at the top, and the sensor has the best receiving state.The vibration of the earthquake drives the inner coil of the sensor to move around the magnet, which leads to the magnetoelectric conversion, and the coil generates the induced electromotive force;We provide GPS clock signal to ensure the real and effective value of each sample point. The temperature sensor can accurately measure the temperature and correct the error caused by temperature, so as to achieve the pursuit of high-precision data quality.Built in Bluetooth module, can use special flat panel and software to carry out real-time equipment index QC and data quality QC.Equipped with external power interface, it can be used for long-term monitoring.
