• max. 3 A (< 5 ms) at 260 V AC
Power supply failure
Lasting min. 1 power cycle:
• EEPROM or T-DAT (Promag 53 only) retain the measuring system data in the event of a power supply failure
• S-DAT: exchangeable data storage chip which stores the data of the sensor (nominal diameter, serial number,
calibration factor, zero point, etc.)
Potential equalisation
Standard case
Perfect measurement is only ensured when the medium and the sensor have the same electrical potential. Most
Promag sensors have a standard installed reference electrode which guarantees the required connection. This
usually means that additional potential matching measures are unnecessary.
Note!
For installation in metal pipes, it is advisable to connect the ground terminal of the transmitter housing to the
piping. Also, observe company-internal grounding guidelines.

Caution!
For sensors without reference electrodes or without metal process terminals, carry out potential matching as
per the instructions for special cases described below. These special measures are particularly important when
standard grounding practice cannot be ensured or extremely strong matching currents are expected.
