24.4 Overvoltage protection for (transit time) sensor connectors

24.4.1 Basic protection - equipotential bonding cable

NIVUS recommends that an equipotential bonding cable is used to connect the sensor enclo-

sure to the control cabinet/transmitter ground as a basic protection measure for the transit time

sensors’ interfaces. The equipotential bonding cable prevents the flow of a transient equalizing

current through the transmitter and the cable shields.
The equipotential bonding cable needs to be at least 4 mm

in diameter and it should run

parallel to the sensor cables.

The following is an example of the use of an equipotential bonding cable.

1) Low impulse earthing resistance required

24.4.2 Extended protection - overvoltage protection “SonicPro T”

“SonicPro T” surge protectors are required for the transit time sensors in non-standard applica-

tions.
Special cases are:

•

Potential differences

that cannot be avoided

can occur

between the sensor enclo-

sure and the control panel/transmitter earthing. These potential differences may be

transient.

This can be caused by

The grounding resistance of the grounding electrode is too high.

This typically means that the leakage current of the mains supply overvoltage

protection device cannot be discharged to the required extent via the earth

connection of the control cabinet installation, resulting in a potential difference.

Or the equipotential bonding cable to the transit time sensors may be undersized

or too long; or it is incorrectly connected or missing.

Or a combination of these conditions.

•

Overvoltages may affect

the transit time sensor’s enclosure

directly

. This effect can

occur via the mounting device, the sensor cable or the medium (water-based liquids).

Install overvoltage protection on each sensor individually

“SonicPro T” overvoltage protectors need to be

individually installed for each

connected

transit time sensor

Use of “SonicPro T” surge protectors

The transmitter sensor signal terminals are electrically isolated from the sensor cables by the

“SonicPro T” overvoltage protectors. The modules thus guard the transmitter from impulse

voltages injected from the sensor; they can also limit a compensating current flowing to the
