Ex devices: see supplementary operating instructions
4 Process pressure
Refer to the table "Process pressure limits" that follows and "Pressure/temperature table for probe selection" in the

2.7.2 General information for nozzles
CAUTION!
Follow these recommendations to make sure that the device measures correctly.
Figure 2-10: Recommended nozzle dimensions
1 Recommended conditions: h ≤ d, where h is the height of the tank nozzle and d is the diameter of the tank nozzle.
2 The end of the nozzle must not have an extension into the tank. Do not install the device on a high nozzle.
CAUTION!
If the device is installed on a high nozzle, make sure that the probe does not touch the side of the
nozzle (attach the probe end, ...).
INFORMATION!
It is possible to measure in these conditions with a minimum top dead zone. Use the snapshot
function to filter the parasite signals from long nozzles. For more data, refer to the Handbook.

3 The electromagnetic (EM) field generated by the device. It has a radius of Rmin. Make sure that the EM field is clear of
objects and product flow. Refer to the table that follows.
4 If there are too many objects in the tank, install a bypass chamber or stilling well.
5 Keep the probe straight. If the probe is too long, shorten the probe length. Make sure that the device is configured with
the new probe length. For more data on the procedure, refer to the handbook.
6 Empty space necessary for double probes. Refer to the table that follows.

2.9 Installation recommendations for solids
2.9.1 Nozzles on conical silos
We recommend that you prepare the installation when the silo is empty.
DANGER!
Risk of electrostatic discharge (ESD): The device is resistant to electrostatic discharges of up to
15 kV (30 kV with the ESD protection option - recommended for solid applications), but it is the
responsibility of the fitter and the user to prevent ESD.
CAUTION!
Install the nozzle in the correct position to measure correctly and prevent too much bending and
traction.

2.11 Electromagnetic compatibility
The device design agrees with European Standard EN 61326-1 and EN 61326-2-3 when installed
in metallic tanks.
You can install the device on open-air tanks and tanks that are not made of metal. This agrees
with Emissions requirements for industrial environments (class A). For data on Immunity
requirements, refer to the note that follows.
CAUTION!
If you install a device with a rod or cable probe in a non-metallic tank or open-air pit, a strong
electromagnetic field near to the device can have an unwanted effect on the accuracy. Use a
device with a coaxial probe for this type of installation.
INFORMATION!
Device operation agrees with residential-class (class B) emissions and industrial-class (class A)
immunity requirements if:
• the device has a single or double probe (rod or cable probe) and is used in a closed tank made
of metal or
• the device has a coaxial probe.

DANGER!
All work on the electrical connections may only be carried out with the power disconnected. Take
note of the voltage data on the nameplate!
DANGER!
Observe the national regulations for electrical installations!
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex
documentation.
WARNING!
Observe without fail the local occupational health and safety regulations. Any work done on the
electrical components of the measuring device may only be carried out by properly trained
specialists.
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.

Connect the wires to the device. Obey the national electrical codes.
Make sure that the polarity of the wires is correct.
Attach the ground to 4 or 7. Both terminals are technically equivalent.
INFORMATION!
If the polarity is not correct, this will not cause damage to the device. But the device will not
operate and the output will be 0 mA.

4.1 Start-up checklist
Check these points before you energize the device:
• Are all the wetted components (probe, flange and gaskets) resistant to the product in the
tank?
• Does the information on the signal converter nameplate agree with the operating data?
• Did you correctly install the device on the tank?
• Do the electrical connections agree with the national electrical codes?
DANGER!
Before you energize the device, make sure that the polarity and the supply voltage are correct.
DANGER!
Make sure that the device and the installation agrees with the requirements of the Ex certificate
of compliance.
4.2 Operating concept
You can read measurements and configure the device with:
