3.5 Removing and Installing the Shedder Bar
IMPORTANT
• The accuracy is not guaranteed after removing and replacing the shedder bar.
If you require an accuracy guarantee, we recommend having the Yokogawa factory perform
shedder bar removal and replacement.
• Shedder bar replacement should be performed by trained personnel with knowledge of the
product characteristics and safety.
WARNING
• In the case of an explosion protected type instrument, make sure that no explosive
atmosphere conditions are present.
• Before removing the shedder bar, stop the ow and remove any remaining uid.
• When removing or installing the shedder bar, pay careful attention to the handling of the
transmitter case O-rings and shedder bar O-rings to prevent damage and adhesion of foreign
matter.
• Replace O-rings if they are damaged or deformed.
• If there is no lubricant on the O-rings, apply silicone-based grease.
• When replacing or removing the shedder bar, always replace the gasket with a new one.
CAUTION
If the shedder bar is not properly reinstalled after replacing or removing it, the readings may be
a󰀨ected when operation resumes.
