ARAMIS-MSD Moduł Sejsmoakustyczny


Threefold transceiver measurement module – Digitalization and transmission of threefold seismic signal to LKP concentrator (SP/DTSS, SD/DTSS)

  • Provides a digital transmission of seismic signals from M/E Aramis system
  • Transmits the data to on-surface or underground digital receiver (OCGA, OCGD) of the local LKP concentrator (SP/DTSS, SD/DTSS)
  • Synchronizes the generator clocking the AC transducers
  • Reads the parameters of sensors with in-built memory
  • Responsible for digital data gathering used for digital transmission and forming the transmission form
  • Fulfils the requirements group I intrinsically safe index, M1 category, ‘ia protection level
  • Compatible with concentrators at ‘ib’ protection level
