Sensor Ventilation - ABB 265GS Operating Instruction

6.8

Sensor ventilation

For technical reasons, you must apply atmospheric pressure to the reference side of the
pressure sensor.
An external ventilation opening, which is protected by a PTFE filter, is provided on the
measuring equipment for this purpose. You should, however, make sure that this ventilation
opening is not covered (e.g., do not paint over it or apply oil containing silicone).
IMPORTANT (NOTE)
Covering the ventilation opening will result in inaccurate measurements.
