2.1 Overview
Cable gland Fixing holes
Internal antenna Status LED
Product label
2.2 Description
The NETRIS®3 transmits data over long distances by means of innovative LPWAN®
technology (“Low-Power Wide-Area Network”). It is therefore possible to carry out
installations inside buildings, in cellars or in underground tanks without any problems.
The transmission of the measured values to the IIoT platform is carried out at a preset
sending interval.The measurement and sending intervals, and also the alarm limits,
for particular measured values can be configured over the LoRaWAN®protocol. A
configuration can be carried out via the cloud.
2.3 Functional principle
The measuring signal is transmitted digitally from the WIKA measuring instrument via a
cable to the NETRIS®3 and wirelessly via the antenna of the radio module to a gateway.
The NETRIS®3 uses the LoRaWAN®radio standard, class A, which is designed for
energy-saving operation.
This means that communication with a suitable gateway mainly consists of uplinks
(messages originating from the measuring instrument). An uplink always occurs in regular,
preset cycles (transmission rate).The measuring rate can be defined independently of the
2. Design and function

6WIKA operating instructions, model WIKA NETRIS®3
14521664.02 03/2023 EN/DE
EN
transmission rate. If an alarm limit is exceeded or dropped below during a measuring cycle,
a data transfer is carried out immediately, regardless of the set transmission rate.
After a successful uplink, two time-limited windows can be used for the downlink (message
to the measuring instrument).This enables bidirectional communication and the receipt of
network control commands. If this possibility is not used, the end device can only receive
data after a new uplink.
→ For details, see website: https://lora-alliance.org
Typical uplinks:
■Measured values: depending on the particular measuring instrument
■Process alarms: can be set accordingly
■Technical alarm: reflects the status of the instrument as well as the quality and reliability
of the measurement.
■The alarm of the radio unit: based on the overall condition of the system. If this alarm
occurs, the occurrence of a process alarm and also the cyclic measured values must be
looked into
■Notifications for fault diagnosis
■Configuration ID (for the identification of changes in the measuring and sending rate)
Typical downlink:
Configuration change (e.g. measuring rate, sending rate, alarm parameter etc.).
The WIKA radio unit automatically detects, in the case of messages to be confirmed (e.g.
alarms), that the transmission packet has not arrived and transmits it again with changed
transmission properties (spreading factors) until the receipt is confirmed by the system.
Higher spreading factors lead to an increased range, a longer sending time
and also an increased energy consumption of the radio device.
2.4 Connection to IIoT platform
The instrument is connected to a LoRaWAN®gateway and the measured values are
transmitted to the IIoT infrastructure at freely configurable intervals. For instrument-specific
registration data for the LoRaWAN®network, see quick start guide (included in delivery).
2.5 LoRaWAN®specification
For the data transmission NETRIS®3 uses LoRaWAN®version 1.0.3.

3.8 Special conditions for safe use (X conditions)
Under certain extreme circumstances, the non-metallic enclosure may generate an
ignition-capable level of electrostatic charge.Therefore the equipment shall not be installed
in a location where the external conditions are conductive to the build-up of electrostatic
charge on such surfaces. In addition, the equipment shall only be cleaned with a damp
cloth.
3.9 ATEX information
The WIKA model NETRIS®3 radio unit carries a marking for zone 0.Therefore,
the WIKA radio unit may be installed and used in zones 0, 1 and 2.
Since the WIKA model NETRIS®3 radio unit is always operated in combination with a
WIKA measuring instrument (e.g. with model PGU2x.100), the instrument with the lower
Ex zone specifies the entire Ex zone.Thus, in the lower case, Ex zone 1.The WIKA
PGU2x.100 measuring instrument is certified for use in zone 1.The NETRIS®3 radio unit
is certified for use in zone 0.The assembly of these two instruments may, thus, only be
operated in Ex zone 1 areas.

3.10 Data transmission security
As part of the join procedure, a mutual authentication between a LoRaWAN®end device
and the LoRaWAN®network is established.This ensures that only real and authorised
devices are connected to real and authentic networks.
LoRaWAN®applications are origin-authenticated, integrity-protected, replication-protected
and encrypted. Combined with mutual authentication, this protection ensures that network
traffic has not been altered, comes from a legitimate device, is not understood by wiretaps,
and has not been intercepted and replayed by unauthorised third parties. In addition,
end-to-end encryption protects the usage data of applications exchanged between end
devices and application servers.
The security mechanisms mentioned are based on the standardised cryptographic AES
algorithms.These algorithms have been analysed by the cryptographic community for
many years, are recognised by NIST and are widely accepted as best security practice for
sensor nodes and networks.
LoRaWAN®security uses the cryptographic principle of AES cryptography in combination
with several operating modes: CMAC2 for integrity protection and CTR3 for encryption.
Each LoRaWAN®device is personalised with a unique 128-bit AES key (AppKey)
and a globally unique identifier (EUI-64-based DevEUI), both used during the device
authentication process.

permissible operating conditions (see chapter 9 „Specifications“).The temperature at the
case of the instrument must not exceed a value of 60 °C [140 °F].The limit value at the
instrument must be fulfilled by taking appropriate measures, e.g. mounting with a distance
from large, hot surfaces or vessels.
Notes on radiation characteristics
■To achieve the best possible sending quality, the radio link from the antenna to the
receiving gateway should be as free from barriers as possible.
■The signal strength is from slightly to severely affected by concrete walls, metal
shielding, shells and hilly landscapes.
■For the best possible transmission power of the antenna, no metal objects, such as
pipelines, may be closer than 10 cm [3.94 in] to the antenna.

18 WIKA operating instructions, model WIKA NETRIS®3
14521664.02 03/2023 EN/DE
EN
Radiation characteristics
When installing the radio unit, the following principles must be observed in order to fully
utilise the radiation characteristics of the antenna:
■There should be no components such as metal pipes, control cabinets, etc. in the
viewing direction to the LoRa®gateway. Concrete parts that contain reinforcement,
and buildings made of concrete, can also have a negative impact on the radiation
characteristics. Any barrier between the radio unit and the gateway can negatively affect
the transmission quality.
■Mount the radio unit as high as possible. Use the maximum cable length for this
purpose.
■In order to ensure the maximum transmission power of the antenna, there must be no
metal objects, such as pipes, closer than 10 cm [3.94 in] to the antenna.
■Optimum radiation characteristics are achieved when the radio unit is mounted with the
z-axis pointing upwards (see „Fig. Radiation characteristics“).
■The receiving gateway should be in line of sight to the y-axis in order to obtain optimal
transmission power (see „Fig. Radiation characteristics“).

Information on the installation of the receiving gateway
Position the gateway in such a way that the transmission power is optimally utilised. For
this, the following recommendations should be observed:
■Depending on the application, a gateway for indoor or outdoor use should be selected.
■Between the instrument antenna and the gateway, there should be as few barriers as
possible (e.g. walls and hills).
■The radiation characteristics of the antenna must be taken into account when
positioning the gateway.
■If the measuring instruments are located on one level, vertical mounting of the LoRa®
antenna on the gateway is recommended.
■The location should ideally be in the middle of the area to be covered.
■Ensure that the gateway is mounted at a sufficient height and is not covered by anything
in the immediate vicinity.The higher the gateway is positioned, the further the LoRa®
connection reaches.
Permissible vibration load at the installation site
The instruments should always be installed in locations free from vibration load. If
necessary, it is possible to isolate the instrument from the mounting point, e.g. by installing
a flexible connection line between the measuring location and the instrument and mounting
the instrument on a suitable bracket.
If this is not possible, the following limit values of the weakest link must not be exceeded:
Frequency range < 150 Hz
Acceleration < 0.5 g (5 m/s²)
The permissible vibration load when mounting the WIKA radio unit on the
rear of the case of the WIKA model PGU2x.100 measuring instrument is
determined by the component with the weakest limit values.
Temperature load
The installation of the instrument should be made in such a way that the permissible
operating temperature, also considering the effects of convection and thermal radiation,
neither exceeds nor falls below the permissible limits.
5.3 Activating NETRIS®3 (active mode)
The active mode is used as the main operating mode with the full functionality of the
LoRa®communication.
Only activate the WIKA model NETRIS®3 radio unit from storage mode to active mode
using the activation magnet included in delivery.
