5.6 Electrical connection - hydraulic force measuring unit with built-in pressure
sensor
To prevent interferences from coupling into the system, please observe the
following information:
■
Use only shielded and low-capacitance measuring cables (for cables, see chapter 10
“Accessories”). These cables fulfil the conditions.
■
Ground the shield of the measuring cable.
■
Connect the cable shield with the case of the hydraulic compression force transdu-
cer. 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 (for cables, see
chapter 10 “Accessories”).
■
Do not install measuring cables in parallel to 3-phase-current cables and control
cables.
■
Avoid stray fields of transformers, motors and contactors.
■
Transducers, amplifiers and processing or display units must not be grounded sever-
al 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.
When using extensions, 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 be taken also to ensure a
high-quality connection of the shielding.
