Fast detailed description:
 

HJ-8 type piezoelectric detector is mainly used for marine geological exploration. With the receiving frequency band range of housing design, unique wide and high sensitivity. The maximum depth is 100 meters. Mainly used in marine areas, rivers, lakes, swamps and transition zone etc.. This product adopts unique polyurethane material and process for packaging. Has the characteristics of corrosion resistance, abrasion resistance, anti water pressure. Cable and casing injection molding as a whole, has unique waterproof function.

The HJ-8 series products are on the early stage of piezoelectric geophone renewal. The main performance in the overall performance, and improved receiving oscillator. Early products using four receiver oscillator for receiving. Using series parallel certain relationship between each vibrator is connected. Poor consistency between the big disadvantage of this connection is the oscillator. Due to the positive, reverse piezoelectric effect, and the noise interference response in response to a vibrator can cause other oscillator. This will directly affect the seismic data resolution. In order to meet the needs of high resolution seismic exploration, HJ-8 products will be changed into a single oscillator receives oscillator. To eliminate the influence between each other, improve the signal fidelity, in order to adapt to the high resolution seismic exploration.
