Potential equalization
Requirements
Please consider the following to ensure correct measurement:
• Same electrical potential for the fluid and sensor
• Remote version: same electrical potential for the sensor and transmitter
• Company-internal grounding concepts
• Pipe material and grounding
Terminals
• For device version without integrated overvoltage protection: plug-in spring terminals for wire
cross-sections 0.5 to 2.5 mm
2
(20 to 14 AWG)
• For device version with integrated overvoltage protection: screw terminals for wire cross-sections
0.2 to 2.5 mm
2
(24 to 14 AWG)
Cable entries
• Thread for cable entry:
• For non-hazardous and hazardous areas (not for XP): G ½"
Cable specification
Permitted temperature range
• The installation guidelines that apply in the country of installation must be observed.
• The cables must be suitable for the minimum and maximum temperatures to be expected.
Signal cable
Current output 4 to 20 mA
A shielded cable is recommended. Observe grounding concept of the plant.
Pulse/frequency/switch output
Standard installation cable is sufficient.
Connecting cable for remote version
Connecting cable (standard)
Standard cable

1)
UV radiation may cause damage to the outer jacket of the cable. Protect the cable from exposure to sun
as much as possible.
