Introduction
This manual is for use with NT®
Pressure Transducers for vacuum
applications, single-port and flow-
through models 4150 and 4250.
These instruments have been
designed for use in high purity
applications in the semiconductor
industry and are compatible with
highly corrosive processes.
These products feature no moving
parts and no filled cavities, which
reduces the possibility of a contami-
nated process. The wetted parts of
these nonmetallic transducers are
constructed with PTFE, sapphire
or other similar high purity inert
materials.

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.

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.

Power Supply Requirements
Figure 1. Power Required for a 4-20 mA Loop
Load Resistance: Current Output
(4-20 mA Configuration)
If a load resistor, RLoad, is used in
series with the current output, the
value of RLoad is dependent on the
supply voltage and the meter resis-
tance and is calculated from the
following formula.
where:
RLoad = maximum load
resistance (ohms)
VPS = power supply voltage (volts)
Rmeter = meter resistance (ohms)
(typically not used, therefore Rmeter = 0)
Rwire = resistance of
interconnecting wire

The pressure transducer requires a
12-28 volt DC power supply with less
than 2% ripple at 100 or 120 Hz. The
required power supply voltage varies
with the load resistance (RLoad),
please refer to the diagrams below
and the formulas on page 9.
The power supply must provide
clean power and must be used only
to power similar measurement-type
devices. The power supply must not
be used to power inductive loads,
such as motors, relays or solenoids.
These devices may produce tran-
sients that may affect the pressure
transducer measurements when the
inductive device is powered-up or
powered down.
NOTE: Be sure to ground the
shield of the cable to local ground.

Operating Environment
The pressure transducer is to be
mounted in a well vented and con-
trolled environment. Refer to the
Reference section on page 13 for
additional specifications.
Process Connections
To avoid possible pressure leaks,
make sure all process connections
have been performed in accordance
with the Mechanical Installation
guidelines on page 6.
Pressure Transducer
Cover Assembly
NT®Pressure Transducer covers
are factory sealed and should not be
tampered with or opened. Opening
the cover shall void the product
warranty.
NOTE: Any attempt to remove or
tamper with the transducer cover
will void the warranty and damage
the unit.
Temperature Requirements
The pressure transducer is rated
for use with fluids at process
temperatures between 50° to 95°F
(10° to 35°C) under normal
operating conditions.

WARNING!
The pressure limits for NT®
Pressure Transducers models
4150 and 4250 decrease sig-
nificantly for temperatures
above 95°F (35°C) Please
consult the factory.
Pressure Reference Accuracy
The accuracy of the pressure trans-
ducer output is ±1% of span. For
example, a -12 to 30 PSIG ranged
pressure transducer has a span of
42 PSIG and an accuracy of ±0.42
PSIG. This accuracy includes the
effects of linearity, hysteresis and
repeatability, measured at room
temperature.
Unit Operation Linear Output Signal

Troubleshooting the NT®Pressure
Transducers may be accomplished
by measuring the output signal of
the pressure transducer with a
battery powered current/voltage
meter. The meter may be placed in
series with the pressure transducer
to measure the current output or it
may be used to directly measure the
voltage output.
Using the battery powered current/
volt meter is an effective method to
determine whether the device or the
on-site data acquisition system is not
functioning properly.
