A WTB 4 system has two components: One WTB 4, connected to the source, detects the trigger pulse from the source and then transmits it to the seismograph The second WTB 4, connected to the seismograph, receives the message from the source and starts the seismograph. Each WTB4 unit consists of: Internal Radio Trigger Module (RTM) Internal 3 Watt VHF radio Internal 99 watt-hour rechargeable battery ...

... additional legs ensures the required coupling for ground motion registration. Any type of geophones can be used with the LandStreamer – vertical, horizontal, horizontal compensated, multicomponent (3C). LandStreamer is compatible with any multi-channel seismograph and can be manufactured with the required number of receivers and the step between them. An important feature of the design is the ability to quickly disconnect the seismic receivers from the platform. Number of sensors 12 ÷ 96 Interval ...
