SLI18 Hand-held read-out
unit
The SLI18 is a high accuracy hand-held
read-out unit that can be used with a variety of sensors. SLI18's most common
application is with heat flux- and solar radiation sensors. It can be used both
for mobile measurements and as an amplifier directly connected to a PC. The SLI18
has an RS-232 interface and software for readout via PC.
Figure 1 SLI18 connected to a solar radiation sensor
or a heat flux plate. (sensors are not part of
the delivery) Other sensors can be
connected as well; please consult AITNIX. The 9-pin RS232 connection
is located on the bottom.
Using the buttons and software menu on the
SLI18, the sensor type and the calibration factor of that sensor are entered. The
reading on the display now shows a calibrated value with the correct engineering
units. SLI18 can be used to make mobile measurements, and also as an accurate
microvolt amplifier for use with a PC. The SLI18 is battery powered but also has
a connection for a mains adapter that is typically used in indoor applications.
An adapter (100-230 VAC - 50/60 Hz) is included in the delivery.
The SLI18 not only measures but also
integrates the input signal. The daily totals of the integrated value are
stored. Up to 31 days can be stored. The totals can be read from the
display.
Delivered includes PC software. The software
has the following functions: - display real-time values - make a graph
with selectable sample interval - store data with selectable sample
interval - read-out and store integrated totals (24 hr totals or from one
manual reset to the next)
SUGGESTED USE
