Magnetic float level transmitters are used for the electrical continuous remote display of levels. The resistance
is converted into a (0)4 - 20 mA analogue signal by means of a transducer and the reading is output on
a digital or analogue display. The spa located at the level of the current level magnetic system transmits
through the wall, the height of the level to the resistor chain. The resistance is converted into a (0)4 - 20 mA
analogue signal by means of a transducer and the reading is output on a digital or analogue display.
9.1 Functional description of the magnetic float level transmitter
9. Magnetic float level transmitter
9.2 Electrical connection of the magnetic float level transmitter
The electrical connection must be set up in accordance with the safety regulations for installation of electrical
systems, which are applicable in the country of installation, and may only be carried out by specialists.
The magnetic float level transmitter is to be connected in the junction box in accordance with the connection
plan. The magnetic float level transmitter is to be wired with the electronic transmitter connected in the
outgoing circuit.

Magnetic float level transmitters with integral head measuring transducers are to be connected in accordance
with the connection plan in the junction box. Information on terminal assignment can be found in the relevant
connection plan. The connection data can be found in the appropriate operating instructions.
9.3 Attention
• The operator must ensure that devices that have an earth connection are earthed.
• Devices with a connection cable are not earthed and may be live if faults occur. These devices may only
be operated at low voltage.
• There is a risk of malfunction in common laying with unshielded cables.
There are to use shielded connection cables. These are to be grounded on one side.
• Ensure that the energy input is correct and sufficient.
9.4 Maintenance of the magnetic float level transmitter
The devices must be installed and commissioned by an expert. In use, the devices do not require
maintenance as long as the parameters such as the temperature and protection category are maintained.
