(A),HJ-8 type piezoelectric detector

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.

(B),HJ-8C-Ⅱ double detector (for submarine cable )

HJ-8C- II dual detector unit is used to compensate for the lack of ocean exploration P wave reception. Not only for the exploration of the sea can also be used in the transition zone of exploration.

HJ-8C- II dual detector unit with two high performance super land geophone with universal structure and a piezoelectric detector is composed of. Liquid damping land inspection can guarantee the universal structure has good coupling effect and prevent outside of background noise on the land checking interference. Piezoelectric geophone with high sensitivity and 0 ~ 100m depth. A double detector unit adopts polyurethane sealing. Has a good waterproof performance. Assurance of security double detector work normally. Its unique shell protection, can avoid the double detector from outside of the impact damage. At the same time with the bandage hole can make the use of binding and submarine cable.

HJ-8C- II dual detector unit land geophone can choose according to need. Can choose conventional geophone in economic efficiency, also can choose high performance super geophone small tolerance. Housing design can guarantee the unique working depth of 200 meters, but because of its use and piezoelectric geophone array, so the working depth of concrete by pressure deep electric detector working limit.
