Product Name: Three Dimensional 3D Geophone From 1Hz to 100Hz Available for Deep Seismic Acquisition and Ground Micro-Tremor Survey Model NO.: 3D Geohpone Horizontal Line: 2 Vertical Lines: 1 Accuracy: <1mm Geophone Direction: X,Y and Z Geophone Type: From 2Hz to 100Hz Optional Triaxial Geopone Shell: Waterproof metal Case Spares Equipped: Adjust Screw Spikes, 7-Pin Short Circuit Sockets Trademark: SEIS TECH Transport Package: Standard Export Carton Specification: 2Hz to 100Hz Origin: China HS Code: 9015900090 Product Description ST series Three Dimensional (3D) Geophone is a type of electromechanical conversion device. Inside of the 3D geophone, three mutually perpendicular geophone elements are arranged in Cartesian coordinates, which means that the vertical geophone element is Z direction, the east direction horizontal geophone element is X direction, and the north direction horizontal geophone element is Y direction, by which the Seismic signals in the three directions of X, Y and Z will be taken simultaneously and converted into electrical signal outputs.ST Series 3D geophones are fully compatible with deep seismographs in deep seismic exploration. Also they are the ideal choice for natural earthquake prediction and detection, pulsating micro seismic measurement of bridges& highways, and other applications of low frequency seismic investigations.- High sensitivity, low distortion, good consistency, good linear response, and reasonable damping coefficient.- Rugged structure, good sealing and excellent waterproof performance.- Horizontal adjustment device and direction indicator equipped.- Waterproof metal Case, 3Nos. of Adjusting Screws, 7-Pin Short Circuit Socket and 1.5meters of leading out cable are also equipped.- Three Dimensional Geophone Type:2Hz, 2.5Hz, 4Hz, 4.5Hz, 10Hz, 15Hz, 28Hz, 30Hz, 38Hz, 40Hz, 60Hz and 100Hz are available.Contact with us to get a quotation.
