The towed seismic streamer SplitMultiSeis streamer 24 ch/2/diff is designed to be used as a receiving system for conducting high-resolution seismic surveys in the water area using SBP, HRS, VHRS, UHRS and others techniques. The sensitive elements of the braid are highly sensitive hydrophones with pre-amplified signals. The number of channels in the braid is 24 pcs. Liquid silicone - PMS 200 is used as a filler. It is possible to use a scythe to implement a deep-seated surveillance system.

The principle of operation of the device

The towed seismic streamer SplitMultiSeis streamer is designed to receive and amplify seismic vibrations and transmit them to a seismic station located on a geophysical vessel. When conducting seismic surveys at sea (rivers), piezoelectric seismic receivers (hydrophones) are used, in which the excess pressure in the water associated with the arrival of a seismic wave is converted into an electrical signal. The sensing element is piezoceramics, with contacts for transmitting an electrical signal. The seismic receivers are placed in a neutral buoyancy receiving device – a marine seismic streamer, which is a polyurethane hose filled with liquid.To operate the device, an external 24 V DC power supply is required, which ensures the operation of piezoceramic signal pre-amplifiers.
