RADIO TRIGGER

Seismic accessory

Versatile, user friendly instrument, designed to "trigger" the acquisition of the seismograph via radio, transmitting in the free European band 869.4 - 869.65 MHz (free use license - exempt from government taxes). Especially practical for long distance (in particular for seismic tomography); it avoids spreading the trigger extensions in the site: the basic system consists of a Tx transmitter (which connects to the piezoelectric trigger or the starter geophone) and a Rx receiver (which instead connects to the seismograph). As for the use of any portable transceiver, the radio trigger and its antenna must be positioned correctly to ensure optimal operation (open spaces and free from obstacles, conditions of visibility between transmitter and receiver, etc..).
