Cable and Supplies Inc.

Digital Hydrophone Digital Hydrophone is a new kind of acoustic single collection equipment. It joins hydrophones with amplification modulation circuit, collection, storage, and digital data transfer. Digital cable can be 70 meters, standard USD interface, easy to connect with the computer system. It is very convenient to build up noise measurement and observation treatment system without using complex parts like: front amplifier, filter, and collector. This hydrophone improves system reliability and anti-interference. It has the character of low noise, wide dynamic range, collection precision high, display absolute sound pressure value and relative sound pressure value. Our company also services the point system as customer requests, including more channels, different lines and interface, inset drive routine and so on. Customer also can get DSP processor development for 2nd time. Independent intellectual property rights, the best quality at a reasonable price. Gene...

The seismic wave field is measured by geophones or hydrophones. The output is electrical signals. The data from the geophones are initially amplified at the preamplifier which is the voltage. It is then passed through an analog low-cut filter. The data are filtered by the analog high-cut filter so that frequencies above Nyquist are removed and then amplified again. Geophones are remarkably simple devices, unlike what you might think. The active element of the device consists of a mass hanging on a spring, like gravity meters. The mass wants to remain motionless when the ground moves. Geophone has been used by geophysicists and seismologists to convert ground movement into voltage. It is a ground motion transducer. The Seismic response is any deviation in this measured voltage from the baseline. It is used for analyzing the earth’s structure. The key factor in a geophone is Resonance frequency. Resonance frequency has to be low for the measurement of low-frequency signa...
