Wind & Weather
The UMB (Universal Measurement Bus) system is a new technology for recording
environmental data. But why?

Hydrology, meteorology, weather conditions
on the roads, agricultural meteorology, energy
applications, renewable energy, high speed
trains, air quality measurements – These various applications all have the same demands
at their core:■ high precision■ durability■ maintenance-free■ innovative
However, the technical requirements can bevery different:■ solar operation■ connected to mains■ operation in all imaginable conditions –including extreme conditions
Last but not least, the transducers neededby our clients are very different:■ compact build■ stand alone sensors■ a combination of stand-alone
with built in transducers■ ability to connect own transducer
In order to fulfil these many different needs
and desires, Lufft has committed itself to
UMB technology.
The catalogue of UMB sensors includes different series of intelligent weather probes fortemperature, relative air humidity, precipitation, air pressure, wind, solar radiation andfurther data.
Our titan range was developed for use in themost extreme conditions. Various series meet
professional meteorological requirements,
starting with our professional series whichmeets all WMO criteria, whereas the weather
sensors in our gold and platinum series are
ideal for even higher levels of precision.
All UMB sensors use a standard electric connector system, meaning that installation andservice tasks are made as simple as possible.
Sensors not belonging to the series or existing analogue sensors can also be connectedto the UMB system via an ANACON UMB
module. Furthermore, a four channel UMB
transformer module is currently being worked
on, which would enable up to four analogue
sensors to be used with the UMB system.
All UMB sensors use a standardized data interface for data retrieval. Currently, there arevarious options for this including SDI12, ASCII,
Modbus und UMB. If the data retrieval unit
is integrated in the Lufft Smart Sensor WSxx,
the other WSxx probes can be added with basic parametrization.
The probes’ channel based data retrieval
provides a multitude of calculable values inmetric and US customary units. This meansthat a converter function is not necessary in
the interface. With the aid of free configuration software (UMB-Config-Tool), sensors canbe configured, systems tested and firmware
updated.
Furthermore, Lufft offers a range of software
packages for data retrieval from weather stations (COLLECTOR) all the way up to packages for web visualisation (SmartView3).

The WS500-UMB and WS600-UMB deliver all meteorological measured
data for Lufft’s high-quality measuring networks. By means of thedigital interface, they can be perfectly integrated into the measured
data architecture of the entire system. When it comes to road trafﬁc
meteorology (“Green ITS”), quality is playing a more and more
important role: In the future, trafﬁc guidance and air pollution will
depend on each other. This can only be realized with precise
measured data, especially in large cities.

Integrated design with ventilated r­ adiation
protection for measuring:- Air temperature- Relative humidity- Precipitation intensity- Precipitation type
- Precipitation quantity- Air pressure- Wind direction- Wind speed
Relative humidity is measured by meansof a capacitive sensor element; a precision NTC measuring element is used tomeasure air temperature.
Precipitation is measured by a 24 GHz
Doppler radar, which measures the drop
speed of an individual drop of rain/snow.
Precipitation quantity and intensity arecalculated from the correlation between
drop size and speed.
The difference in drop speed determines
the type of precipitation (rain/snow).
Maintenance-free measurement ­offers
a major advantage over the common
tipping spoon and tipping bucket­processes.

GeneralInformation

Precipitation is measured by a 24 GHz
Doppler radar, which measures the drop
speed of an individual drop of rain/snow.
Precipitation quantity and intensity arecalculated from the correlation between
drop size and speed.
The difference in drop speed determines
the type of precipitation (rain/snow).
Maintenance-free measurement offers
a major advantage over the common
tipping spoon and tipping bucket processes.
Measurement output can be accessed by
the following protocolls:

QualitySensors

It is difﬁcult to believe that rain density can be measured, that asensor can record the speed of precipitation and the size of therain drops. In such cases, high-tech sensors can be extremely
precise and meticulous in detail. When it is a matter of trafﬁc
safety, then Lufft Measuring Technology knows no excuses!

Lufft R2S-UMB – Precipitation Sensor(Present Weather Detector)
The drop speed is captured with a
24-GHz-Doppler radar.
The precipitation quantity and intensity is
calculated from the correlation between
drop size and speed.
The type of precipitation (rain, snow,
sleet, freezing rain, hail) is detected fromthe difference in drop speed.
The measurement data is available forfurther processing in the form of a standard protocol (Lufft UMB protocol).

Each sensor of the WS family has an extra input
channel to connect a remote temperature sensor.

The temperature sensor measures thesurface temperature, eg. the surface
temperature of a solar module.
This remote temperature sensor can be
combined with any sensor of the WS
family.
A typical application is to combination
with WS301-UMB or WS501-UMB as areference sensor how efficient a solar
system works.

Lufft UMB Configuration Software
A Lufft intelligent weather sensor gives
you a choice of various settings. The config tool allows you to choose the correctones, such as:
Choosing the data channels needed foryour purpose. As well as raw data, these
could include calculated values such as
the dew point. The data can be shown ineither metric or US customary units.
Recording the data in a text document during test runs. This form of protocol andarchiving with date stamp can also be
useful for field testing
Loading the most recent firmware in theintelligent probe. Continual improvements
and function enhancements can therefore
simply be installed during maintenance.
Should you prefer not to alter the setting
yourself, a local Lufft Partner is available
to aid in the correct configation of your intelligent measuring device.
