Product Description
Low Frequency Microtremor Survey Sensor Displacement Velocity Acceleration Measurement
Low-frequency microseismic measurement sensors are an important tool for seismic monitoring and environmental vibration analysis, and their main function is to accurately measure small ground vibrations. The sensor is capable of sensitively capturing multiple physical quantities such as ground displacement, velocity and acceleration at low frequencies, and is widely used in geological exploration, municipal engineering and building health monitoring.
Features of the low-frequency microseismic measurement sensor include high sensitivity, broadband response and high stability. It is capable of monitoring vibrations at very low frequencies, making it suitable for capturing foundation settlement and near-ground microvibrations. At the same time, the sensor has a high dynamic range, allowing it to effectively handle vibration signals of varying intensity. In addition, its structural design is usually more robust, enabling it to maintain stable measurement performance in complex environments.
Application:
Low-frequency microseismic measurement sensors are widely used in many fields such as earthquake research, urban construction and environmental protection. In earthquake research, the sensor can help scientists analyze the propagation mechanism of seismic waves, providing important data support for earthquake prediction. In urban construction, low-frequency microseismic measurement sensors are used to monitor the vibration of buildings to ensure engineering safety and stability. In addition, in the field of environmental monitoring, the sensor can assess the impact of traffic noise and industrial vibration on the surrounding environment, to help develop appropriate environmental protection measures.
