Product
The 5TB houses an accelerometer that is designed for strong-motion borehole studies. in cased holes with diameters of 99 to 203 mm
The triaxial analogue sensor can be combined with a borehole or surface digitiser to build a fully networked, integrated borehole monitoring system.
The instrument is supplied with surge protection and a strain relief mechanism to isolate the sensors in the instrument from vibrations in the cable.
Flat acceleration output from DC to 100 Hz (200 Hz option)
89 mm diameter for installation with a hole-lock into cased holes with a diameter of 99 to 203 mm
76 mm diameter for post-hole installation with no hole-lock
Waterproof and durable with O-ring seals throughout
Suitable for installation with sand backfilto minimise convection
Duaoutput (high and low gain) and optionahigh/low pass filters
Optionaelectronic compass module to determine downhole attitude
Remote DC offset zeroing
