No Comments on Borehole Triaxial Geophone 10Hz

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).

Adopting leaf spring type mechanical well locking structure to ensure that the probe part and the well wall have certain coupling strength. The smaller the well diameter, the stronger the coupling strength, which will reflect seismic signals more truly.
Adopting specialized cable in light weight and strong tensile strength (tensile strength for the cable is more than 200 kgs).
The electromagnet only works when it goes down to the well and has no effect on the signal receiving. Seismic signals in the three directions are output separately, and the interference between channels is very small.
The outer part of the device is made of special metal material with rugged structure.
Applicable well diameter range from 60mm to 200mm.
NK2721C Connector, Split Spring Clips or Free Cable End Optional.
