Digital Pressure Sensor with CANopen
2.8 Recommended Grounding
If there is a provision to ground the enclosure at the applica-
tion being used, use the recommended grounding method as
shown in Figure 1.
Figure 1. Recommended Shielding Diagram 1
If there is no provision to ground the enclosure in the applica-
tion, this shielding method is preferred for wires that run longer.
The shielding of the cable can be connected to CAN_SHLD of
the connector (pin 1 of M12 or Pin A of Bendix) and it can be
grounded at the far end (see Figure 2).

NOTES:
2. Includes pressure non-linearity (BFSL), pressure hysteresis and non-
repeatability. Thermal errors are not included.
3. Differential sensors are calibrated in positive direction and accuracy
specification is valid in positive direction only.
4. Includes zero error, span error, thermal effect on zero, thermal effect
on span, thermal hysteresis, pressure-non-linearity, pressure hyster-
esis and non-repeatability.

ATTENTION
1.
The wet/wet differential pressure sensor has two
separate, welded Hastelloy
unit, the wet port (high port) has all-welded stainless
steel and Hastelloy
construction. The dry port (low port)
®
has no isolation diaphragm.
2.
Includes pressure non-linearity (BFSL), pressure
hysteresis, and non-repeatability. Thermal errors are not
included.
3.
Differential sensors are calibrated in positive direction
and accuracy specification is valid in positive direction
only.
4.
Includes zero error, span error, thermal effect on zero,
thermal effect on span, thermal hysteresis, pressure-
non-linearity, pressure hysteresis, and non-repeatability.
