Wireless synchronization system (WSS-1)


on request
Item ID: wss-1


The product was successfully added to basket
Main features:
  • Maximum operating distance — 250 m
  • Compatible with ELLISS-3 seismograph

Wireless synchronization system (WSS-1) is designed to work with modern seismographs. WSS-1 externally launches the seismograph at the same time as seismic vibrations source discharged. The launch moment of the source is transmitted via 868 Hz radio channel (this frequency does not require permission of The General Radio Frequency Centre of Russia). Seismograph start-up delay is constant and is equal to 100 μs, what is an outstanding characteristic from similar products. Guaranteed operating distance of WSS-1 is 250 m in the area-of-sight. It is possible to significantly improve the performance of geophysical investigations if using WSS-1 synchronizer, due to absence of synchronization line. WSS-1 consists of transmission and receiving units.
