GeoSIG's latest seismic recorder
offering— nair (rhymes with fire, named after Swiss
peak Piz Nair)—is the groundbreaking latest generation of the GeoSIG Measuring
Systems with highest performance, excellent operational flexibility and
enhanced connectivity. With its optimized installation, operation and
maintenance philosophy, nair offers an abundance of
features and options. Its user-replaceable modular electronic boards make nair extremely
maintainable and future-proof.
It includes an Ethernet connection and optionally a Wi-Fi (b/g/n) module to
ensure fast and reliable data transfer. Both wired and wireless network
interfaces can be used simultaneously. Its design and efficiency make it ideal
for any application requiring seismic instruments. It boasts an impressive
147db (0.02-20Hz), making it suitable for weak-motion precision recording as
well. Numerous optimisations within the architecture and the design yields
unprecedented performance for seamless and fast execution of all system
processes.
The instrument’s software processes data in real time. If triggered by a
seismic event, nair calculates a number of Event
Parameters and reports them to a data centre immediately. nair is
a self-contained instrument and is equipped with numerous power options. The
instrument uses an “Intelligent Adaptive Real Time Clock” (IARTC) with
self-learning temperature compensation, improving the accuracy of the RTC or
TXCO significantly. The IARTC is able to synchronize with GNSS (GPS, GLONASS,
BeiDou and Galileo) to provide high timing accuracy. Optionally the unit itself
can act as an NTP server as well.
The instrument can be locally connected to a laptop through its ports for
configuration, testing or data retrieval. The same functions are available
remotely as well. Wired or Wireless Interconnected Network option enables the
use of several units together in a time and trigger synchronised manner. There
are multiple data storage options available.
nair is fully compatible with existing GeoSIG sensors
and can co-exist and co-perform in the same network as the GMS series
recorders. The simple upgrade path makes nair "future
proof."
