The OMEGA®WMS-16 Modular
Weather Station is a computer­based 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
direction, air temperature,
relative humidity for temp/
humidity, barometric pressure,
precipitation, data logging, tripod
and mast, solar radiation shield,
cables and mounts. Additional
sensor options include solar
radiation, water or soil temperature,
auxiliary air temperature, or rain
gauge upgrade.

The unique modular system design
provides plug-and-play functionality
for adding or replacing sensors.
The WMS-16 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 WMS-16D
data acquisition module includes
selectable averaging intervals,
12-bit analog conversion, 0.1% FS
accuracy, 2 alarm outputs, and
optional modem communications.
The standard system includes a
120 Vac power adaptor and RS232
serial port for connection to a
personal computer. For outdoor or
remote applications, a NEMA 4X
enclosure and rechargeable battery
option is offered.

WMS-16NEMA-S,
modular weather
station with NEMA
enclosure and solar
power, $3308.

The optional software package
provides a real-time text display,
as well as a real-time graphical
display, or an ASCII row and
column format may be selected.
In addition, the data acquisition
module is compatible with
Windows®HyperTerminal software
and other terminal programs.
