This measuring system uses gamma rays. Therefore take note of the
instructions for radiation protection in chapter "Product description".
Anyworkonthesourcecontainermayonlybecarriedoutunderthe
supervisionofaqualiedradiationprotectionocer.
1.5 EU conformity
ThedevicefullsthelegalrequirementsoftheapplicableEUdirec-
tives.ByaxingtheCEmarking,weconrmtheconformityofthe
instrumentwiththesedirectives.
The EU conformity declaration can be found on our homepage.
Electromagnetic compatibility
Instrumentswithplastichousingaredesignedforuseinanindustrial
environment. Nevertheless, electromagnetic interference from electri-
cal conductors and radiated emissions must be taken into account,
asisusualwithclassAinstrumentsaccordingtoEN61326-1.Ifthe
instrumentisusedinadierentenvironment,theelectromagnetic
compatibility to other instruments must be ensured by suitable meas-
ures.
1.6 NAMUR recommendations
NAMUR is the automation technology user association in the process
industry in Germany. The published NAMUR recommendations are
acceptedasthestandardineldinstrumentation.
ThedevicefullstherequirementsofthefollowingNAMURrecom-
mendations:
•
NE 21 – Electromagnetic compatibility of equipment
•
NE 43 – Signal level for fault information from measuring transduc-
ers
•
NE53–Compatibilityofelddevicesanddisplay/adjustment
components
•
NE107–Self-monitoringanddiagnosisofelddevices

1.7 Security concept, Bluetooth operation
Sensor adjustment via Bluetooth is based on a multi-stage security
concept.
Authentication
When starting Bluetooth communication, an authentication is carried
outbetweensensorandadjustmentdevicebymeansofthesensor
PIN. The sensor PIN is part of the respective sensor and must be
enteredintheadjustmentdevice(smartphone/tablet).Toincrease
adjustment convenience, this PIN is stored in the adjustment device.
This process is secured via an algorithm acc. to standard SHA 256.
Protection against incorrect entries
In case of multiple incorrect PIN entries in the adjustment device,
further entries are possible only after a certain amount of time has
passed.
