Nivector FTI26

Measuring principle

Measuring system

The sensor surface of the Nivector evaluates the different dielectric values of air and bulk solids. If
the bulk solids come into contact with the sensor surface, the electronics change the switch status.
The Nivector can be switched to either minimum of maximum fail-safe mode, ensuring quiescent
current operation in all applications. The switch status is indicated by an LED. A guard electrode
eliminates interference factors due to the vessel wall or possible buildup, for example.

Depending on the fail-safe mode selected and the level, the Nivector switches and signals in the
following cases:

• When point level is reached

• In the event of a problem

• In the event of a power failure (electrical switch is locked)

The measuring system comprises a Nivector point level switch, e. g. for connecting to PLCs or an IO­Link master as per DIN EN 61131-9. A suitable miniature contactor or a solenoid valve can be
connected directly to the point level switch.

 1 Application examples

1 Overfill protection or upper level detection (MAX)
2 Dry-running protection or lower level detection (MIN)

1)

• Safety-related switching: MIN or MAX point level. The electrical switch opens if the point level is
reached or if faults or a power outage occur.
– Maximum point level detection (MAX): e. g. for overfill protection

The device keeps the electrical switch closed as long as the sensor is not yet covered by medium.
This is also the case for devices with IO-Link if the measured value is inside the process window.

– Minimum point level detection (MIN): e. g. for dry-running protection

The device keeps the electrical switch closed as long as the sensor is covered by medium. This is
also the case for devices with IO-Link if the measured value is outside the process window.

Function monitoring

In the order configuration: With two-channel evaluation, functional monitoring of the sensor is also
possible in addition to level monitoring, provided that no other monitoring option has been
configured via IO-Link.

When both outputs are connected, the MIN and MAX outputs assume opposite states (XOR) when
the device is operating fault-free. In the event of an alarm condition or a line break, both outputs are
de-energized.

IO-Link is a point-to-point connection for communication between the measuring device and an IO­Link master. The measuring device features an IO-Link communication interface type 2 with a
second IO function on pin 4. This requires an IO-Link-compatible assembly (IO-Link master) for
operation. The IO-Link communication interface enables direct access to the process and diagnostic
data. It also provides the option of configuring the measuring device while in operation.

pressure.

Reasons:

According to Article 2, point 5 of EU Directive 2014/68/EU, pressure accessories are defined as
"devices with an operational function and having pressure-bearing housings".

If a pressure instrument does not have a pressure-bearing housing (no identifiable pressure chamber
of its own), there is no pressure accessory present within the meaning of the Directive.
