Geotomographie - Model BHC5 - Hydrophone String for Borehole Receivers
The hydrophone string BHC5 is used to receive P-waves in water filled boreholes. This receiver is used for P-wave tomography is a standard method for high-resolution geological structure exploration between boreholes. P-waves are generated in one borehole and being transmitted to the other. P-wave tomography measurements are easy to analyze due to the easy recognition of the first arriving seismic waves.The BHC5 reciever consists cable drum, hydrophones ...

Geotomographie - Model BGK5 - Borehole Geophone
The borehole geophone BGK5 is used to receive P- and S-waves in dry or water-filled boreholes. The geophone can be mainly applied for crosshole tests using the BIS-SH-DS seismic source and the generator IPG800 and downhole tests with e.g. a Sledge Hammer. This borehole geophone BGK5 consists of four horizontal sensors, separated by 45° intervals, and one vertical sensor. The geophone is coupled to the borehole wall by a pneumatic clamping system ...

Geotomographie - Model DDS - Dual Downhole System
The Dual Downhole System (DDS) is used to receive P- and S-waves in dry and water filled boreholes in order to determine interval velocities. The DDS consists of two stations each equipped with tri-axial sensors. The stations are mechanically connected to each other to ensure the alignment of all horizontal sensors. Both stations are coupled to the borehole wall by a pneumatic clamping system (inflatable bladder). Air is supplied to the DDS through an ...

Geotomographie - Model MBAS-D - Digital Multistation Borehole Acquisition System
The Digital Multistation Borehole Acquisition System (MBAS-D) is a digital three-component geophone string used to receive P- and S-waves in dry or water filled boreholes. It can be used for S-wave borehole tomography or downhole surveying. Up to ten individual stations with tri-axial sensors can be connected. The system is especially designed for S-wave borehole tomography. S-wave tomography links high-resolution borehole geophysics to soil dynamic ...
