Honeywell PX2 Installation Instructions Manual

Installation Instructions for the

PX2 Series Heavy Duty Transducers

GENERAL INFORMATION

Honeywell’s PX2 Series Heavy Duty Pressure Transducer is
a portfolio of highly congurable pressure sensors that use
piezoresistive sensing technology with ASIC (Application Specic
Integrated Circuit) signal conditioning in a stainless steel housing.
The PX2 Series is fully calibrated and compensated for offset,
sensitivity, temperature effects and non-linearity using the on­board ASIC.

OVERPRESSURE

CAUTION

PRODUCT DAMAGE

• Do not exceed the overpressure.

Failure to comply with these instructions may result in
product damage.

If the overpressure rating is exceeded, the life of the PX2 Series
may be reduced and electrical failure may occur. Both static
and dynamic overpressure must be considered, particularly in
hydraulic system applications. Hydraulic pressure uctuations
can have very high and very fast peak pressures, as in a water
hammer effect.

An oscilloscope is recommended for determining if high-pressure
transients exist in a system. If system pressure pulses are
expected, choose a transducer with a pressure rating high enough
to allow continuous operation at the highest expected pressure
spikes.

A pressure ‘snubber’ may be used to reduce the peak pressure
applied to the transducer.

MEDIA COMPATIBILTY

CAUTION

PRODUCT DAMAGE

• Use non-abrasive, chemically compatible media to prevent
damage to diaphragm or port materials.

Failure to comply with these instructions may result in
product damage.

The PX2 Series uid path is an assembly of 304 stainless steel,
epoxy, alumina, glass, and silicon.

Ratiometric voltage devices require either a regulated 3.3 Vdc (AA
and AB) or a regulated 5.0 Vdc supply (AC and AD), (see Table 2).
All other versions can use an unregulated supply within the ranges
noted under the excitation specications. Ensure the power supply
is off while wiring.

ELECTROMAGNETIC ENERGY/NOISE

CAUTION

PRODUCT DAMAGE/ERRATIC OPERATION

• Do not use in areas where electromagnetic energy may affect
transducer operation.

Failure to comply with these instructions may result in
product damage.

The PX2 Series has been rated for high immunity to electrical
noise; however, care should be taken when used around high
voltage sources that emit high levels of radiated electromagnetic
energy like variable frequency motor drives, solenoids, radio
transmitters and engine ignition systems. The use of shielded
cable and grounding of pressure port is also recommended.

FUNCTIONAL TEST

1. Connect the transducer to a dc voltage supply (off). The supply
voltage should be set within the range specied for the model.

2. Based on the transducer’s specied output, connect the output
lead(s) to a digital dc or mA meter.

3. With no pressure on the transducer, turn on the power supply
and read the output signal on the voltmeter. The reading
should correspond to the specication indicated for null offset.
If not, check the connections, wire color code and the setting
of the power supply.

CAUTION

PRODUCT DAMAGE

•

Ensure torque specications are determined for the specic

application. Values provided are for reference only. NPT ports
are not specied with torque values. Correct installation
is based on the number of Turns From Finger Tight (TFFT).
(Mating materials and thread sealants can result in
signicantly different torque values from one application to
the next.)

• When using NPT ports in stainless steel manifolds, use
a thread sealant with anti-seize properties to prevent thread
galling. Ensure the sealant is rated for the application.

• Use appropriate tools (such as an open ended wrench or
deep well socket) to install transducers.

• Always hand-start transducers into the hole to prevent cross
threading and damage.

• Do not subject the transducer to high temperatures from
soldering, brazing, or welding of the system plumbing

Failure to comply with these instructions may result in
product damage.

WIRING INSTRUCTIONS

The wiring code for electrical connection is shown in Figure 3.

Table 2. Electrical Specications

NOTICE

• To ensure proper environmental sealing and electrical
connections when using a connector, follow the connector
manufacturer’s installation guidelines.

• All terminal cavities must be sealed using the correct wire
gauge and seal combination.

• If only two leads are used, any additional terminal cavities
should be sealed per the connector manufacturer’s
installation guide.

• Honeywell recommends using a crimping tool for crimping
wires to the connector terminals.

• Contact the individual connector manufacturer for connector
wiring.

Notes:

2. Operating Temperature Range: The temperature range over which the product will produce an output proportional to pressure but may not remain
within the specied performance limits.

3. Storage Temperature Range: The temperature range over which the product may safely be exposed without excitation or pressure applied. Under
these conditions the product will remain in specication after excursion to any temperatures within this range. Exposure to temperatures outside
this range may cause permanent damage to the product.

4. Compensated Temperature Range: The temperature range (or ranges) over which the product will produce an output proportional to pressure
within the specied performance limits.

5. Overpressure: The absolute maximum rating for pressure which may be safely applied to the product for it to remain in specication once pressure
is returned to the operating pressure range. Exposure to higher pressure may cause permanent damage to the product.

6. Burst Pressure: The maximum pressure that may be applied to the product without causing escape of the pressure media. The product should not
be expected to function after exposure to any pressure beyond the rated burst pressure. This rating is also the case burst rating of the product.

7. Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) tted to the output measured over the pressure range at 25 °C.
Includes all errors due to pressure non-linearity, pressure hysteresis, and non-repeatability.

8. Offset Error: the maximum deviation in the output signal obtained when the reference pressure is applied at 25 °C relative to the ideal transfer
function.

9. Full Scale Span (FSS): The algebraic difference between the output signal measured at the maximum (Pmax.) and minimum (Pmin.) limits of the
pressure range.

10. Total Error Band: The maximum deviation from the ideal transfer function over the entire compensated temperature and pressure range. Includes
all errors due to offset, full scale span, pressure non-linearity, pressure hysteresis, repeatability, thermal effect on offset, thermal effect on span,
and thermal hysteresis.

11. Response Time: The response time of the transducer is the maximum amount of time that the transducer will take for the transducer to output a
change from 10% to 90% of full scale in response to a 0% to 100% full scale step input pressure range.

Output is proportional to the difference between applied pressure and a built-in xed reference to vacuum (zero pres-

sure), where the minimum operating pressure is set to absolute zero pressure (perfect vacuum).

Output is proportional to the difference between applied pressure and a built-in xed reference to 1 atmA, where the

minimum operating pressure is set to 14.7 psiA (1 atmA).

Sensor measures pressure relative to ambient pressure. Output is proportional to the difference between applied pressure

and atmospheric (ambient) pressure, where the minimum operating pressure is set to atmospheric pressure.
