LogBox, a small rugged 2-channel Data Logger.
Now available from Audon Electronics is the LogBox,
a small rugged 2-channel stand alone datalogger.
This logger has up to 2 universal analogue input channels
which can accept mV, 4-20mA, most thermocouple types
and Platinum Resistance Thermometers.
The LogBox accurately records the input channels with 12-bit
resolution and stores them in non-volatile memory. Over 8000
readings can be stored per channel. Log rates can be set from
0.5 seconds to 30 days. The logger is completely self-contained,
and the internal battery can last for typically over 1000 days. The
logger is housed in a small rugged IP65 plastic enclosure with
signal cable entry via a side mounted cable gland. An IP68 rated
version can be supplied to special order.
The LogBox is configured and logged data is retrieved using the
LogChart software and an RS232 based Infrared wand. This IR
wand communicates with LogBox through a transparent window
so that there is no need to open the LogBox lid. The IR Wand
simply connects to a free RS232 port and is pointed at the
LogBox IR window. No external power supply is needed.
The LogChart software is used to configure the inputs channels
for sensor type, channel name, engineering units and log rate.
A logging session title can also be input to uniquely identify the
data. Not only can the LogBox record instantaneous input values,
but the maximum, minimum or average readings over the last
specified number of samples can be recorded instead. Logging
can be started immediately, or on a specified time on a specific
day. The LogBox can be programmed to stop logging when the
memory is full, on a specific time and day, after a set number
of recordings or data can be set to wrap round and over-write
the oldest data.
The LogChart software can also download the logged data
and display it in tabular and graphical formats. Data can be
saved to a Spreadsheet compatible ASCII file for analysis.
