The Model T9M260278 Modular Weather Station is a
computer-based meteorological system designed as
a “user-friendly” solution for data storage and real-
time monitoring of weather conditions. The
standard package includes:
Wind Speed
Wind Directions
Air Temperature
Relative Humidity
Barometric Pressure
Precipitation
Data Logger
Mast
Solar Radiation Shield for
temp/humidity
Mounts
Set-Up Disk
Additional Sensor options include solar
radiation, water or soil temperature, auxiliary
air temperature, rain gauge upgrade,
evaporation and soil moisture.
The unique modular system design provides
plug-and-play functionality for adding or
replacing sensors. The T9M260278 Data
Acquisition Module includes the following
features larger nonvolatile memory, selectable
averaging intervals, 12 bit analog conversion,
0.1% F.S. accuracy, two alarm outputs, and
ptional modem communications. o
The T9M260278 is supplied with an attractive
desktop data acquisition module with a memory capacity of 128KB RAM (approximately
45 days at 15 minute intervals with 6 sensors). The standard system includes a 120Vac
power adapter and RS232 serial port for connection to a personal computer. For outdoor
or remote applications, two enclosure options are available. One is for sites with AC
power and the other utilizes a solar panel. Both options include a NEMA-4X enclosure
and rechargeable battery to allow continued operation in the event of power failure.
Data can be viewed using Windows HyperTerminal or other terminal programs such as
Procomm. A one page real-time text display or an ASCII row and column format may be
selected. A menu is provided for setting the date and time, alarms, logging interval etc.
Optional graphical displays software is available for viewing real-time and historical data
charts and graphs.
