Dual Seismic Sensor


Dual seismic sensor is a kind of seismic sensor, especially used for marine seismic detection. It combines velocity geophone of high sensitivity and special structure with marine piezoelectric geophone into one. Electric connection with special structure overcomes the bad contacting caused by large deformation and fatigue of spring leaf, so dBsl dual sensor offers more steady and durable performance. That is the combination unit of geophone and hydrophone with greatly enhanced quality of seismic data. We can compress ghost reflection and sea moving noise better.This product has two types: dBsl-10A and dBsl-10B.Features:1) With high fidelity input and low resistance block output, it can meet the needs of water area high precision seismic prospecting development2) The type of interior over-line greatly advances working stability and waterproof quality of dBsl dual sensor3) Unique electric connection makes mechanical noise of interior sensor descend lowestTechnical criteria for dBsl dual sensor (dBsl-10):1) Natural: 10Hz±3.0%2) Coil resistance: 395Ω±3.0%3) Sensitivity damping: 27.6V/m/s±3.0%4) Open circuit damping: 0.680±3.0%5) Distortion:6) Spurious frequency: beyond 25Hz7) Moving mass: 8.4g8) Coil travel: 1.8mm9) Weight: 78g10) Dimensions (D x L): Ф27.4 x 31.711) Opening temperature: -40°C - 80°C12) Damping constant: 4,925Ω
