Thiết bị tạo xung bề mặt Geotomographie WTU1
The wireless trigger unit WTU1 is used to replace trigger cables if e.g. roads or rivers prevent a continuous seismic measurement. The wireless trigger unit WTU1 works with nearly all impulse sources including sledge hammers.
The wireless trigger unit WTU1 consists of two boxes which include the sender and the receiver unit. The sender will be connected to the source and the receiver to the seismograph. The sender and receiver units are placed in small and robust plastic cases which allow an easy operation.
