Sealing
Laying the capillaries
Chemical seal CSB • for VEGADIF 65
•
Leave the measuring system in the packaging until mounting to
protect it against mechanical damages
•
When removing the packaging and when mounting, take special
care to avoid mechanical damage and deformation of the dia-
phragm
•
Do not carry the pressure transmitter by holding the capillary line
•
Do not bent the capillary lines. Kinks can cause leakage and lead
to an increase in response time
•
Never loosen sealed screws on the chemical seal or the pressure
transmitter
•
Do not damage the isolating diaphragm: scratches on the isolating
diaphragm (e.g. from sharp subjects) are the main areas where
corrosion can occur

Mounting instructions

•
Suitable seals must be selected for sealing
•
For flange mounting, use a seal with a sufficiently large inner diam-
eter and place the seal centrically; contact with the diaphragm will
cause measurement deviations
•
When using soft material or PTFE seals, take note of the regula-
tions of the seal manuffacturer, particularly with respect to torque
and settling cycles
•
Lay in vibration-free areas to avoid additional pressure fluctuations
•
Do not lay close to heating or cooling lines
•
Insulate in case of colder or warmer ambient temperatures
•
Bending radius of the capillaries ≥ 30 mm
