Product overview uvLink radiometer
A cable connection between a sensor and its evaluation/display unit is the means of choice due to its reliability.
However, there are applications where a cable connection can only be realized with difficulty or not at all. Thisapplies, for example, to setups, where the sensor must be positioned in different or difficult-to-access places, or in
the event that dangerous UV radiation prohibits a person from being in the vicinity of the sensor. A wirelessconnection is then useful. Our wireless UV sensor nodes are available for this purpose.
They can be divided into three categories: uvLink One, uvLink Field and uvLink IoT.

uvLink one - Specifications from page 2
The uvLink One consists of a wirelesssensor (node) and a display which
can be connected to a computer via
USB. The display provides the classic
functions of a radiometer, i.e. displayof irradiance, dose measurement,
logging (when connected to thecomputer).

uvLink field- Specifications: docs.sglux.com/radiometers/uvlink
If there are other sensors (nodes) within radiorange, the uvLink One becomes the uvLink
Field. The display becomes a “collector”. The
connected nodes (sensors) and the current
measured value are displayed. The evaluation
is done on the PC using the supplied software„uvLink log“. The „Field“ variant is used whena process is to be evaluated at several points
simultaneously.

uvLink IoT Specifications: docs.sglux.com/radiometers/uvlink
The uvLink IoT is connected via a WiFi network withconnected to an MQTT server. A spatial proximity ofthe sensors to each other or to the display/collector
is not required, in contrast to the two productspresented above. Accordingly, the device is suitable
for measurements at different locations (e.g.) ships,
which are to be evaluated centrally in real time.

getting started
The on/off switch and the USB-C connection for charging are located behind theprotective cap on the sensor (node). The display (receiver) is activated bypressing the red button on the left side of the housing. Pressing the button
twice switches the display off. The display is also charged via a USB-C port.

display functions
The below picture shows the display functions.

the start screen
After switching on the display unit, a start screen opens. The unitof irradiance (in the picture mW/cm2 ) adapts dynamically. Thethree function keys are assigned as follows here:
A dose measurement can be started on the left.
A target dose can be programmed in the center. When it isreached, the device generates a signal tone. The target dose must
be defined before starting the dose measurement.
On the right, the display of the maximum irradiance detected
since the instrument was put into operation can be reset.

management of the target dose
The three function keys for defining the target dose are assigned as follows:
On the left, the dose value can be increased. If the value was accidentally set
too high, the programming must be exited (middle function key) and theprocess restarted.
In the center, the programmed target dose is confirmed. The display returns
to the start screen. The dose measurement then does not start automaticallybut is started on the start screen by pressing the left function key.
The middle image shows the status when the target dose is reached. Inaddition to the acoustic signal, the middle function key is then programmedwith the „alarm“ function. Pressing this function key pauses the dose
measurement and generates the screen shown in the lower picture. There,
the right function key resets the dose measurement. The target dose isretained. The target dose function can be deleted by switching the instrument
off and on again. The left function key resumes the dose measurement. Asthe target dose is then still reached, the alarm tone can be heard
continuously.

options during dose measurement
The left function key („stop“) pauses the dose measurement. Then the dose
measurement can be continued there („continue“).

data logging function
If the display unit is connected to a PC and the „uvLink log“ software is installed there, it is possible to record themeasured values (logging function). Further information is available at: docs.sglux.com/radiometers/uvlink.

spectral sensitivity options
The uvLink One is supplied with a PTB-traceablecalibration and a dynamic range agreed with thecustomer. For most applications, the spectral
sensitivity of a SiC photodiode provides a suitable
receiving characteristic. However, if the source tobe measured also emits UV radiation in awavelength region that is not to be measured,spectrally matched, filtered photodiodes are used.
For measurements around 400nm (e.g. 395nm
LED) we use GaP-based photodiodes. Theoverview on the right shows the different options
for spectral sensitivity.
