Borehole Triaxial Geophone 10Hz ( Borehole 3C geophone 10Hz) is mainly used to receive seismic waves in the borehole well. The triaxial geophone is equipped with three high-sensitivity 10hz geophone sensors arranged in Cartesian coordinates, which can receive seismic signals in three directions simultaneously. The borehole triaxial geophone adopts a torsion spring and electromagnetic well lock device, which is suitable for borehole drilling with diameter 60mm to 160mm (The maximum drilling diameter can up to 200mm by adjusting position of the adjusting screw).
The Borehole Triaxial Geophone 10Hz cable output end can be welded connectors or be kept open as per clients’ requirements, When welding an NK2721C connector, pin 1/2 is the vertical component, pin 3/4 and pin 5/6 are the horizontal component (the single number is the positive pole and even number is negative pole). When welding split clips in the color of red, blue and yellow, the red clip is a vertical component, and the other two clips are horizontal components ( For each split spring clip, the wide plate is a positive pole, and the narrow plate is a negative pole).
