Data acquisition monitoring device SMS / SAS

GeoSIG's SMS/SAS systems are mostly used in Nuclear Power Plant or other Industrial Facility Seismic Monitoring Projects. If you need any further specific information, please do not hesitate to contact us through our agent assigned for this kind of instrumentation for your geographical region or directly. The core of the SMS / SAS is a Central Processing Unit (CPU) with a multi-channel digital recorder system rack mounted in an industrial cabinet together with an industrial computer and relevant peripherals. Accelerometers, seismometers, complete seismic stations or sensor packages, which are referred to as Detection / Recording Units (DRUs), are placed at remote locations and can be connected to the CPU. The system has been designed in a way that it is not bound to a single topology. There could be only the sensors or both sensors and data acquisition out in the field. Advantages of these topologies are briefly explained in the specifications section. The system has great modularity and flexibility to simplify an instrumentation upgrade and enable existing elements to be reused as much as possible. The system provides added reliability with built-in redundancy of the recorders and power supply, continual SOH software checks, alerts transmitted to multiple sources, and a choice of data back-up. The PSU has quadruple redundancy of the sources. All calculations take place on each recorder, so the PC (CPU) has no critical impact on calculation and analysis of exceedances. The CPU monitors all DRUs in parallel, as a result of the dedicated communication links that are provided by the system hardware.
