Potential equalization

Endress + Hauser
Special cable gland of sensor connecting cables on transmitter side
Sensor cable:
• Use the ready-to-use cables supplied by Endress+Hauser with each sensor pair.
• The cables are available in lengths of 5 m, 10 m, 15 m, 30 m, 60 m and 100 m.
• You can choose between PTFE and PVC cable material.
Operation in zones of severe electrical interference:
The measuring system meets the general safety requirements as per EN 61010 and the EMC requirements as
per EN 61326/A1 (IEC 1326) "Emission as per requirements for class A" as well as NAMUR recommendation
NE 21.
Signal and power cable:
Caution!
Grounding is by means of the ground terminals provided for this purpose inside the connection housing. Keep
the stripped and twisted lengths of cable shield to the terminals as short as possible.
Prosonic Flow 90/93
AC: <18 VA (incl. sensor)
DC: <10 W (incl. sensor)
Prosonic Flow 91
85 to 250 V AC: <12 VA (incl. sensor)
20 to 28 V AC: <7 VA (incl. sensor)
11 to 40 V DC: <5 W (incl. sensor)
Bridging of min. 1 cycle frequency: EEPROM (Prosonic Flow 90) or HistoROM/T-DAT (Prosonic Flow 91
and 93) save measuring system data if power supply fails
For potential equalization, no special measures are necessary.
Note!
For instruments for use in hazardous areas, observe the corresponding guidelines in the specific
Ex documentation.
