Installation
CAUTION! The NT Pressure
Transducer has been factory
sealed. Do not attempt to remove
the coverof the pressure trans-
ducer. Any attempt at removal
of the pressure transducer cover
will void the warranty and damage
the unit.
CAUTION! 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
NT Pressure Transducers utilize
Flaretek®flared tube connections
and must be used with the proper
tubing size and coupling nut.
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.
Fitting size 11⁄44"33⁄88"11⁄22"33⁄44" 1"
Torque (in•lb) 5 8 11 14 30
Care should be taken when installing
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 signal cable are free from
mechanical stress or excessive
bending from the surrounding
equipment.
