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 qualified radiation protection officer.
1.5 EU conformity
The device fulfils the legal requirements of the applicable EU direc-
tives. By affixing the CE marking, we confirm 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 different 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 field instrumentation.
The device fulfils 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 field devices and display/adjustment
components
•
NE 107 – Self-monitoring and diagnosis of field 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.
