2.11 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.
Encrypted Bluetooth communication
The sensor PIN as well as the sensor data
are transmitted encrypted between sensor
and adjustment device according to Bluetooth
standard 4.0.
2.12 Environmental instructions
Protection of the environment is one of our most
important duties. That is why we have introduced an environment management system with
the goal of continuously improving company
environmental protection. The environment
management system is certied according to
DIN EN ISO 14001.
Please help us full this obligation by observing
the environmental instructions in this manual:

3.2 Principle of operation
Application area
The radar sensor NCR-21 is the ideal sensor
for typical applications in the water and waste
water industry. It is particularly suitable for
level measurement in water treatment, in
pump stations as well as storm water overflow
tanks. The flood-proof IP 68 housing of
NCR-21 ensures a maintenance-free
permanent operation. An integrated Bluetooth
module enables the wireless communication
with smartphone, tablet or PC.
Functional principle
The antenna of the radar sensor emits short
radar pulses with a duration of approx. 1 ns.
These pulses are reected by the product and
received by the antenna as echoes. The transit
time of the radar pulses from emission to reception is proportional to the distance and hence to
the level. The determined level is converted into
an appropriate output signal and outputted as
measured value.
3.3 Adjustment
Wireless adjustment
The adjustment of NCR-21 is carried out
via
standard adjustment instruments:
•
Smartphone/tablet (iOS or Android operating system)
•
PC/notebook with Bluetooth USB adapter
(Windows operating system)

The packaging of standard instruments consists
of environment-friendly, recyclable cardboard.
For special versions, PE foam or PE foil is also
used. Dispose of the packaging material via
specialised recycling companies.

ration of the notes on the transport packaging.
Nonobservance of these instructions can cause
damage to the device.
Transport inspection
The delivery must be checked for completeness
and possible transit damage immediately at receipt. Ascertained transit damage or concealed
defects must be appropriately dealt with.
Storage
