Operation in areas of severe electrical interference:
The measuring device complies with the general safety requirements in accordance
with EN 61010, the EMC requirements of EN 61326, and NAMUR recommendation
NE 21.
Caution:
Grounding is by means of the ground terminals provided for that purpose inside the
connection housing. Keep the stripped and twisted lengths of cable shield to the
terminals as short as possible.
85 to 250 VAC: < 12 VA (including sensor)
20 to 28 VAC: < 8 VA (including sensor)
11 to 40 VDC: < 6 W (including sensor)
Switch-on current:
• maximum 3.3 A (< 5 ms) at 24 VDC
• maximum 5.5 A (< 5 ms) at 28 VAC
• maximum 16 A (< 5 ms) at 250 VAC
Lasting minimum 1/2 power cycle:
EEPROM retain the measuring system data in the event of a power supply failure
Power consumption
Power supply failure
Potential equalization
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 potential matching. 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.
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.
