NT® PRE SSURE TRAN SDUCER USER GUIDE
CAUTION!
The NT® Pressure Transducer
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.
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 trans-
ducer process connections.
Installation
Electrical Installation
The pressure transducer provides
an analog (4-20 mA) electrical
output proportional to the pressure
measured.
NOTE:
The white wire is not
required, please refer to the
wiring diagram below.

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.
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 bend-
ing from the surrounding equipment.
