LGT LGT-20D4.5 Seismic Geophone Sensor, 4.5Hz Vertical | Low-frequency detector; seismic exploration; geological survey

LGT-20D4.5 Low Frequency Geophone Sensor is a classic 4.5Hz seismic vibration detector designed for seismic exploration, geological surveys, ground vibration monitoring, and subsurface signal acquisition applications. Compared with higher-frequency industrial geophones, the 4.5Hz low-frequency design provides improved sensitivity to weak and long-period ground vibration signals, making it suitable for traditional seismic prospecting and geological field operations. Featuring stable damping characteristics, reliable low-frequency response, and compact industrial construction, the LGT-20D4.5 is widely used for oil and gas exploration, geological investigation, seismic wave acquisition, vibration experiments, and research monitoring systems. Its low-frequency sensing capability allows effective detection of subtle ground movement and deeper geological vibration signals. With durable metal housing, low distortion performance, and operating temperatures from -40°C to +90°C, this geophone sensor offers dependable field performance for seismic data collection and long-term outdoor exploration applications. The compact 20D series structure also provides convenient integration into portable seismic acquisition systems and engineering survey equipment.
