All work with this product must be carried out by
qualified persons!
1.3 Intended Use
The probes are exclusively suitable for continuous
hydrostatic filling-level measurement.
The user must check whether the device is suited
for the selected use. In case of doubt, please
contact our sales department ([email protected]).
AFRISO assumes no liability for any wrong selection
and the consequences thereof!
The fluids that can be measured are liquids that are
compatible with the materials in contact with the
fluids, described in the data sheet. For application, it
must additionally be ensured that the fluid is
compatible with the parts in contact with the fluid.
The specifications listed in the current data sheet
are binding and must absolutely be complied with. If
you do not have the data sheet to hand, please
request it or download it from our homepage.

3. Mounting
3.1 Mounting and Safety Instructions
airborne parts, leaking fluid,
-
electric shock
- Always mount the device in a
depressurized and de-
WARNING
energized condition!
NOTE – If there is increased risk of damage to the
device by lightning strike or overvoltage, increased
lightning protection must additionally be provided!
NOTE – Install the probe such that any rubbing or
bumping of the sensor head (sensor element), e.g.
against a container wall, is excluded. Observe the
operating conditions such as, for example, flow
conditions. This applies in particular to probes
equipped with cable outlet and to devices with tube
extensions of a length over 2.8 m.
NOTE – Do not remove the packaging or protective
caps of the device until shortly before the mounting
procedure, in order to exclude any damage to the
diaphragm and the threads!
Protective caps must be kept! Dispose of the
packaging properly!
NOTE – Treat any unprotected diaphragm with
utmost care; this can be damaged very easily.
3.2 Mounting Steps for Probes
NOTE – Always immerse the device slowly into the
fluid to be measured! If the probe strikes the liquid
surface, the diaphragm could be damaged or
destroyed.
NOTE – Fasten the probe properly according to your
requirements.
NOTE – Free-hanging probes with FEP cables
should not be used if effects of highly charging
processes can be expected.
As standard, the probe is supplied without fastening
material. Clamp fixing, anchor clamp and mounting
flanges are available as accessories, for different
mounting variants.
3.3 Mounting Steps for fitting set
The mounting thread is clean and undamaged
The O-ring is undamaged and seated in the
designated groove
1. Assemble suitable parts according to demands.
2. Conduct the Cable by the PG11 screw
connection. Note the submersion depth in the
container.
3. Then tighten the single parts of the fitting set by
hand.
If you need a fitting set, this can be ordered from
AFRISO as an accessory (Art. No. 52125).
3.4 Removal of Protective Cap (if equipped)
The probes are equipped with a plastic protective
cap to protect the diaphragm. This has to be pulled
off prior to putting into service if the probe is to be
be
used in a higher viscous fluid such as sludge. This
makes the probe front-flush, and the fluid reaches
the diaphragm.
Removal by hand
1. Hold the probe such that the protective cap
points upward.
2. Hold the probe with one hand on the probe
section
(Fig. 2 – 1).
3. Pull off the protective cap (Fig. 2 – 2) with the
other hand.
Removal using a tool (recommended)
1. Hold the probe such that the protective cap
points upward.
2. Slide a thin tool (Fig. 2 – 8), e.g. a screwdriver,
through two opposite bores of the protective cap
(Fig. 2 – 2).
3. Lever off the protective cap.
NOTE – Do not damage the measuring cell (Fig. 2 –
7) under the protective cap!

3.5 Cable Protection (Optional)
According to order, the probe was supplied with
cable protection; if the probe was prepared for
mounting by means of a stainless steel or PVC tube
(optional), the customer must affix a cable protection
themselves.

4. Electrical Connection
4.1 Connection and Safety Instructions
Improper installation may result
-
in electric shock
- Always mount the device in a
depressurized and de-
WARNING
energized condition!
Explosion hazard if the
-
operating voltage is too high
(max. 28VDC)!
DANGER
Operate the device only within
-
the specification! (data sheet)
The limit values listed in the EC type-
examination certificate are observed.
(Capacity and inductance of the connection
cable are not included in the values.)
The supply corresponds to protection class II.
(protective insulation)
NOTE – for devices with cable outlet
-
When routing the cable, the following minimum
bend radii must be observed:
Cable without air hose:
fixed installation: 5-fold cable diameter
flexible use: 10-fold cable diameter
Cable with air hose:
fixed installation: 10-fold cable diameter
flexible use: 20-fold cable diameter
-
In case of devices with cable outlet and
integrated ventilation hose, the PTFE filter
located at the cable end on the relative pressure
hose must neither be damaged nor removed!
NOTE – Use a shielded and twisted multicore cable
for the electrical connection.
NOTE – If a transition is desired from a cable with
relative pressure hose to a cable without relative
pressure hose, we recommend using the terminal
box with pressure equalizing port (Art. No. 31824).
4.2 Electrical Installation

NOTE – In the case of relative pressure gauges, the
cable contains a ventilation hose for pressure
equalization. Route the end of the cable into an area
or suitable connection box which is as dry as
possible and free from aggressive gases, in order to
prevent any damage
