them for the repair of the system. In

addition, they are authorized to put into

operation, to ground, and to mark circuits

and devices according to the safety

engineering standards.

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.

NOTE – Excessive dust accumulation (over 5 mm)

and

complete

coverage

with

dust

must

prevented!

The device is state-of-the-art and is operationally

reliable. Residual hazards may originate from the

device if it is used or operated improperly.

1.6 Packaging Content

Check that all parts listed in the scope of delivery

are included free of damage, and have been

delivered according to your purchase order:

- probe

- operating manual

2. Product Identification

The device can be identified by means of the type

plate with order code. The most important data can

be gathered therefrom.

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

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.

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

Connect the device electrically according to the

information specified on the type plate, the following

table, and the connection circuit diagram.

possible and free from aggressive gases, in order to

prevent any damage
