Installation
WARNING! The pressure trans-
ducer has been factory sealed.
Do not attempt to remove the
cover of the pressure transducer.
Any attempt at removal of the
pressure transducer cover
will void the warranty and
damage the unit.
WARNING! Do not tighten the
nuts that protect the process
connections during shipment.
Do not tighten the nuts unless the
proper tubing has been installed.
Tightening these nuts may result in
damage to the pressure transducer
process connections.
MECHANICAL INSTALLATION
—
NOTE: For detailed tube flaring
instructions, see “Flaretek tube
fitting flare and assembly procedure”
at
www.entegrisfluidhandling.com
(follow the Fittings>Tube Fittings>
Flaretek Tube Fittings links).
When installing flared tubing to
the pressure transducer, the flared
tube is pushed over the transducer’s
fitting until the fitting reaches the
smaller tube diameter. The amount
of torque required to tighten the
coupling nut is dependent upon
the size of the fitting.

Care should be taken when instal-
ling flared tubing onto the pressure
transducer. Do not use excessive
torque or subject the transducer
to high heat during installation.
The transducer should be firmly
mounted to a solid surface to
ensure stability. Verify that the
pressure transducer and the sig nal
cable are free from mechanical
stress or excessive bending from
the surrounding equipment.
