MP N/O3 Measurement module

Description

Three-component transceiver measurement module – Digitization and transmission of a three-component seismic signal to the LKP concentrator (SP/DTSS, SD/DTSS)

Ensures digital transmission of seismic signals within the ARAMIS M/E system
Transmits data to the surface or underground digital receiver module (OCGA, OCGD) of the local LKP concentrator (SP/DTSS, SD/DTSS)
Synchronizes the clock generator for A/C converters
Reads sensor parameters from built-in memory
Handles the collection of digital data for digital transmission and forms the transmission frame
Complies with intrinsic safety requirements for Group I, Category M1 with protection level ‘ia’
Compatible with concentrators with protection level ‘ib’
