Data loggers made by Wilmers Messtechnik are rugged data acquisition
systems for longterm measurements in harsh environments. Universal measurement
inputs and a simple formula language ensure flexible integration of virtually
any type of sensors. Our data loggers are easy to use and reliable.

The data logger wilog303/306 is
our standard system for wind site assessment and small weather stations.
Because of its low power consumption the
data logger wilog303/306 is an ideal
device for longterm measurements with battery or solar power supply.
Remote data transmission via GSM cellular phone network ensures permanent
control of measurement stations in remote areas.

The network capable data logger blueberry NDL 485
is a modular data acquisition system for complex wind measurements,
wind turbine power curve measurements, environmental monitoring and
meteorological research. It features high sampling rates and a big
data memory for recording of high resolution time series, e.g., from
turbulence measurements with ultrasonic anemometers.
The RS485 bus provides an interface for 'intelligent' sensors
(ultrasonic anemometers, present weather sensors, cloud ceilometers)
and sensor extension modules. The Ethernet port enables the integration
into a PC network (LAN) or a SCADA system. The integrated web interface
offers local access by means of an Internet browser as well as global
access via the Internet. The NDL 485 sends measured
data automatically via eMail and FTP.
The switching outputs of the NDL 485 are used for simple control tasks.
The NDL 485 is characterized by a broad range of communication options
(GSM, GPRS, DSL) that ensure permanent control over remote measurement stations.
