2.1 Overview
Example: plastic version
2.2 Description
The radio unit was developed in order to transmit sensor signals wirelessly. The instru-
ment is connected to a sensor and takes readings from it. These values are made avail-
able in the respective radio protocol.
The radio transmission is achieved via LoRaWAN®based on LPWAN technology
(low-power wide-area network) to enable large transmission ranges and long battery
life, or via Bluetooth®Low Energy.
The instrument is either powered by a battery or optionally has an external power
connection.
The radio unit meets all safety requirements of relevant standards and regulations of the
radio equipment directive for data communication.The radio unit is a product that meets
high requirements and transmits data with excellent reliability.
The transmission of the sensor signal to the IIoT platform is carried out at a preset
sending interval.The sending intervals, and also the alarm limits, can be configured over
the IIoT platform. In addition, the instrument status (current measured value, battery life,
etc.) can also be queried and set on-site via a mobile device using a local interface via
Bluetooth®Low Energy.
2.3 Functional principle
The radio unit uses the Bluetooth®Low Energy 4.2 radio standard which is designed for
energy-saving operation. In connected mode, the radio unit can be configured on-site
using a mobile device with the “myWIKA wireless device” app.
The last measured value recorded is transmitted via Bluetooth®Low Energy in “Adver-

→For details on the Bluetooth®connection, see chapter 3.9 "Data transmission securi-
ty" and the additional documentation “Special documentation for BLE communication
specifications, model NETRIS®1”.
Typical applications
■Signal recording
■Setting the alarm parameters
■Fault diagnosis
■Configuration ID (for the identification of changes in the sending rate)
■Configuration change (e.g. sending rate, alarm parameter etc.)
■Setting of the analogue signal to be measured or the connected RTD signal
The analogue signal or RTD signal to be measured can only be set via
Bluetooth®.

3. Safety
3.1 Intended use
The radio unit wirelessly transmits the measured value of a measuring instrument
connected by cable to a higher-level system. The instrument can be used wherever an
analogue signal or an RTD value is digitalised and made available via Bluetooth®Low
Energy or LoRaWAN®. Remote monitoring of the analogue signal or RTD value can be
made through a web-based platform.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specifications contained in these operating instructions must be
observed. Improper handling or operation of the instrument outside of its techni-
cal specifications requires the instrument to be taken out of service immediately and
inspected by an authorised WIKA service engineer.
Handle electronic instruments with the required care (protect from humidity, impacts,
strong magnetic fields, static electricity and extreme temperatures, do not insert any

objects into the instrument or its openings). Connectors and female connectors must be
protected from contamination.
The manufacturer shall not be liable for claims of any type based on operation contrary
to the intended use.
3.2 Improper use
This instrument is not permitted to be used in hazardous areas!
For applications with direct contact with foodstuffs this instrument is not suitable.
Refrain from unauthorised modifications to the instrument.
The remote monitoring function must not be used for control purposes, as it
cannot be guaranteed that data packets won't be lost during radio transmis-
sion.
The LoRaWAN®signal may only be used for mobile applications to a
limited extend.This applies particularly to high spreading factors.
Any use beyond or different to the intended use is considered as improper use.
Do not use this instrument in safety or emergency shutdown devices.This radio unit is
not suitable for use as a controller or for control and regulation purposes.
WARNING!
Danger of fire
The use of non-approved batteries can lead to personal injury, damage to
the instrument and the environment due to fire.
▶Only use approved batteries, see chapter 9 "Specifications".
3.3 Responsibility of the operator
The instrument is used in the industrial sector. The operator is therefore responsible for
legal obligations regarding safety at work.
The safety instructions within these operating instructions, as well as the safety,
accident prevention and environmental protection regulations for the application area
must be maintained.
The operator is obliged to maintain the product label in a legible condition.
