SDI-12 Data Loggers Description
The iRIS 350 SDI-12 data loggers have been
designed and constructed for use in harsh
outdoor and industrial environments. The
data loggers are housed in a special
die-cast special corrosion resistant
aluminum alloy case with a hard anodized
finish. A neoprene gasket provides the
seal allowing the data loggers to have a
IP65 rating. The SDI-12 data loggers
include an integral rechargeable 12V battery
within the casing making it ideal for remote
data collection or outdoor environmental
data monitoring. The SDI-12 data loggers
can be easily attached to an existing
structure using the four 3/16" (M4) blind
mounting holes in rear of case and powered
by solar panels connected directly to the
data loggers. For remote SDI-12 data
collection the iRIS 350 SDI-12 data loggers
provide an affordable, self-contained remote
data logging solution without the need for
separate weatherproof cabinets or boxes.
NOTE: The optional weather resistant data
logger housing with external battery is
required if analog sensors are connected to
the data logger. The heavy-duty SDI-12 data
loggers also feature a password protected
network login and multi-line LCD for onsite
diagnostics, data browsing and
configuration.
The iRIS 350 SDI-12 data loggers support
a maximum of six external sensors. Sources
for these sensors may be chosen from
physical digital or analog inputs or virtual
sources (via serial communication or
calculations). Each of the data logger's
sensors has two associated alarms, each with
separate trigger and reset levels. Each
alarm also has a duration, which is used to
delay the alarm trigger for analog inputs
and to determine the time over which pulse
input counters should be totalized (rainfall
etc). Three additional sensors are reserved
by the data loggers for internal
measurements (battery voltage, supply
voltage and temperature). The data loggers
record data from all enabled sensors in a
four word (8 byte) compressed format which
includes full date and time to fractions of
a second.
As well as the 4 analog inputs, 4
configurable digital I/O channels, the iRIS
350 SDI-12 data loggers also include an
SDI-12 interface to allow the connection of
at least 10 SDI-12 instruments.
The iRIS 350 SDI-12 data loggers can
provide remote data measurements using
wireless Internet connectivity that is
provided to the data loggers via an internal
modem. Depending on the application and
target market, the data logger's modem will
be one of the following:
- Dual-band 900MHz/1800MHz GSM/GPRS
- Single-band 1900MHz GSM/GPRS
- CDMA/CDMA-1X
- HSDPA (Next G®)
This modem also supports the alternative
connection options of CSD (Circuit Switched
Data) and SMS (Short Message Service).
These options require the appropriate
service to be enabled by the wireless
service provider.
