2.2 Description
Through the modular design, the model PGU2x.100 pressure gauge is designed for
operation with the model NETRIS®3 radio unit.The radio unit can be fixed, for example,
directly to the back of the instrument case.
Under the influence of pressure, the pressure elements deform within their elastic limits.
A mechanical movement transfers this deformation into a rotational motion. A magnet on
the pointer shaft rotates proportionally to the instrument pointer as a direct linear function
of the process pressure.The angle sensor contained in the transmitter electronics measu-
res the rotational motion of the magnet in the range 0 ... 270°.The change in angle is
recorded contact-free, and therefore wear-free, and further processed into a digital signal,
which is transmitted to the model NETRIS®3 radio unit.The radio unit ensures the intrin-
sically safe voltage supply for the PGU23.100 and PGU26.100 Bourdon tube pressure
gauges and ensures the transmission of the measured data based on LPWAN® technolo-
gy (“Low Power Wide Area Network”).
The measurement and sending intervals, and also the alarm limits, for particular measu-
red values can be configured over the IIoT platform.
For details on the alarm configuration, see “Special documentation for LoRaWAN®
communication specification”, models PGU23.100 and PGU26.100.
The model PGU2x.100 pressure gauge fulfils safety-related requirements of the relevant
standards and regulations for the on-site indication of the operating pressure of pressure
vessels. The mechanical on-site indication works completely autonomously, i.e. battery-
independent.
Safety version
The model PGU2x.100 is based upon a model 2xx.30 high-quality pressure gauge with a
nominal size of 100, which corresponds to the S3 safety version of the EN 837-1.
Ex version
The models PGU23.100 and PGU26.100 are suitable for use in hazardous areas

The model PGU2x.100 combines a mechanical measuring system with electronic signal
processing and is prepared for connection to the WIKA model NETRIS®3 radio unit.The
instrument is used for measuring pressure in hazardous areas of industrial applications.
The instrument offers many application possibilities for gaseous and liquid aggressive
media that are not highly viscous or crystallising.

The model PGU2x.100 pressure gauge in combination with the model NETRIS®3 radio
unit is used wherever web-based remote monitoring of the process pressure is desired in
addition to on-site indication.
In addition to the pressure value, the instrument temperature is also transmitted digitally.
Due to the position of the temperature probe, which is located on the sensor
circuit board in the pressure gauge case, the instrument tempera-
ture is influenced by the ambient and the process temperature.
Only use the instrument in applications that lie within its technical performance limits (e.g.
temperature limits, material compatibility, ...). In order to achieve an optimal service life

See technical information IN 00.05.
The operator of the plant in which the product is used must ensure the compatibility of the
materials of the wetted parts with the medium used.
The instrument must only be used with media which are not harmful to the wetted parts
over the entire operating range of the instrument. Any change in the state of the matter or
any decomposition of unstable media is not permitted.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specifications of the enclosed operating instructions and the operating
instructions for the NETRIS®3 radio unit must be observed. Improper handling or opera-
tion of the instrument outside of its technical specifications requires the instrument to be
taken out of service immediately and inspected by an authorised WIKA service engineer,
see chapter 9 “Specifications”. If the performance limits are exceeded (e.g. EN 837-1
limits) or if there are visible changes to the instrument, it must be replaced.
WARNING!
Overload limit of the instrument
Pressure values above the overload limit can lead to irreversible damage of
the measuring instrument.
The overload limit must never be exceeded, even when failures occur in
the end-use application.
The manufacturer shall not be liable for claims of any type based on operation contrary to
the intended use.

Assembly
For the application limits of the assembly, compliance with the specifications of the WIKA
radio unit and the specifications of the models PGU2x.100 is required.The permissible
ambient temperature range of the assembly is determined by the instrument with the
lowest temperature range.
The PGU23.100 and PGU26.100 measuring instruments are certified for use in areas
that require EPL Gb (zone 1). The NETRIS®3 radio unit is certified for use in areas that
require EPL Ga (zone 0). The assembly of these two instruments may only be operated in
areas that require EPL Gb (zone 1).
DANGER!
Injuries through improper use
Failure to follow instructions for the assembly can result in death or serious
injury.
Assessment of operability by skilled personnel.
The remote monitoring of the process pressure via radio transmission is only suitable for
non-critical and non-safety-relevant applications.
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.
