4.5hz Geophone Vertical Sensor for Geological Survey Sensitivity 28.8 v/m/s

Model Number:Vertical Power:NO Material:Metal Size:36mm Natural Frequency:4.5Hz Sensitivity:28.8 v/m/s Coil Resistance:375Ω Element Diameter:25.4mm Element Height:36mm Element Weight:86g Model NO.:EG-4.5-II Product Description Geophone Element 4.5Hz Vertical The geophone 4.5hz (EG-4.5-II) is a conventional type of moving coil geophone with small error in working parameters and stable and reliable performance. The structure is reasonable in design, small in size and light in weight, and is suitable for seismic exploration of strata and geological environments of different depths. It is equivalent to SM-6 B coil 4.5hz geophone. Widely used in industrial vibration-monitoring systems. Ideal choice for shear-wave horizontal elements.
