moma monitoring seismic station moma is an integrated programmable and versatile seismic station hosting sensors, data acquisition and recording unit. moma combine both high performance characteristics with easy setup and management. The A/D conversion is based on 6 single-chip analog-to-digital-converter with an integrated, low-noise programmable gain amplifier (PGA) and twochannel input multiplexer (mux). The converter uses a fourth-order delta-sigma (ΔΣ) modulator that provides high resolution performances with more than 130 dB SNR (@250 SPS), low noise (5 nV/√Hz) and high input impedance, allowing easy interfacing to sensors over a wide range of gains. momaOptionally, it is possible to require the with data acquisition and recording unit (without internal sensors)to plug external sensor. In this case the input level is ±20Vpp moma is open-architecture seismic data acquisition system and offer the possibility to customize and provide tailored solutions in according to your specific needs and challenges. Main Features  3Ch geophone (4,5Hz) + 3Ch MEMS (both internal)  32 bit A/D converter  Very low power consumption  Ethernet interface  SeedLink Transmission protocol (latency < 0.3s)  200+ days for 6ch@125sps recording on 64GB microsd card included Applications:  microseismic monitoring  structural health monitoring  volcano monitoring  reservoir monitoring  seismic early warning
