Please consider the following to ensure correct measurement:
• Same electrical potential for the fluid and sensor
• Company-internal grounding concepts
terminals
Spring-loaded terminals: Suitable for strands and strands with ferrules.
Conductor cross-section 0.2 to 2.5 mm
2
(24 to 12 AWG).
Cable entries
• Cable gland: M20 × 1.5 with cable ⌀ 6 to 12 mm (0.24 to 0.47 in)
• Thread for cable entry:

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.
Power supply cable
Standard installation cable is sufficient.
Protective ground cable
Cable ≥2.08 mm
2
(14 AWG)
The grounding impedance must be less than 1 Ω.
Signal cable
Current output 4 to 20 mA HART
A shielded cable is recommended. Observe grounding concept of the plant.
PROFIBUS PA
Twisted, shielded two-wire cable. Cable type A is recommended .
For further information on planning and installing PROFIBUS networks see:
• Operating Instructions "PROFIBUS DP/PA: Guidelines for planning and commissioning"
(BA00034S)
• PNO Directive 2.092 "PROFIBUS PA User and Installation Guideline"
• IEC 61158-2 (MBP)
PROFIBUS DP
The IEC 61158 standard specifies two types of cable (A and B) for the bus line which can be used for
every transmission rate. Cable type A is recommended.
