5.5 Electrical connection - Hydraulic ring force transducer with pressure sensor
To prevent interferences from coupling into the system, observe the following
information:
■
Use only shielded and low-capacitance measuring cables (for cables, see chapter 10
“Accessories”).
■
Ground the cable shield.
■
In the cables of the accessories, the cable shield is connected by means of the
knurled nut, thus connecting it to the case of the pressure sensor.
■
Do not install measuring cables in parallel to 3-phase-current cables and control
cables.
■
Avoid stray fields of transformers, motors and contactors.
■
Force transducers, amplifiers and processing or display units must not be grounded
several times. Connect all instruments to the same protective conductor.
The pin assignment of the connector or of the cable can be found on the product label.
For an extension, only shielded and low-capacitance cables should be used. The
permitted maximum and minimum lengths of cable are defined in ISO 11898-2. Care
should also be taken with the shielding to ensure a high-quality connection.

with mounted pressure sensor
For further information and advice see the appropriate operating
instructions of the mounted pressure sensor.
