700PEx Series Pressure Modules

Instruction Sheet

Introduction

The Fluke 700PEx Series Pressure Modules allow you to
measure pressure with Fluke intrinsically safe calibrators
such as the 718Ex. Read this sheet before using the
pressure modules. This instruction sheet contains
specifications and information about how to avoid damaging
the pressure modules and describes how to safely use them
in hazardous locations. Refer to your calibrator’s Users
Manual

The pressure modules measure pressure using an internal
microprocessor. They receive operating power from and
send digital information to the intrinsically safe calibrators.

• Gage pressure modules have one pressure fitting and

• Differential pressure modules have two pressure fittings

• Absolute pressure modules measure relative to a

Safety Information

In this instruction sheet a Warning identifies conditions and
actions that pose hazards to the user. A Caution identifies
conditions and actions that may damage the pressure
module or equipment under test. International symbols used
in this instruction sheet are identified later in the
section. Read the entire instruction sheet and the 700PEx
CCD (Concept Control Drawing) before using the pressure
module.

In case of doubt (due to translation and/or printing errors)
refer to the original English instruction sheet.

XW Warning

To avoid electric shock, injury, or damage to the
pressure module:

• Use the pressure module only as described

in this instruction sheet and the Fluke
700PEx CCD (Concept Control Drawing)
otherwise the protection provided by the
pressure module may be impaired.

• Inspect the pressure module before use. Do

not use it if it appears damaged.

• Check the cable for damaged insulation. Do

not use the pressure module if the cable
appears damaged.

• Never use the pressure module with the case

open. Opening the case invalidates Ex
Approval.

• This equipment is specified for use in

measurement category I (CAT I) pollution
degree 2 environments and should not be
used in CAT II, CAT III, or CAT IV
environments. Voltage transients should not
exceed 300 volts for the CAT I applications
where this product is used. Measurement
transients are defined in IEC1010-1 as 2 µs
rise time with a 50 µs duration at 50 % of the
maximum amplitude height.

• Measurement Category I (CAT I) is defined

for measurements performed on circuits not
directly connected to the mains.

Faults and Damage

If there is any reason to suspect that the safe operation of
the pressure module has been affected, it must be
immediately withdrawn from use and precautionary
measures must be taken to prevent any further use of the
pressure module in an Ex hazardous area.

XW Warning

The safety features and integrity of the pressure module
may be compromised by any of the following:

• External damage to the housing

• Internal damage to the pressure module

• Exposure to pressure loads in excess of the

maximum rated pressure

• Incorrect storage of the unit

• Damage sustained in transit

• Correct certification is illegible

• Functioning errors occur

• Permitted limitations are exceeded

• Functioning errors or obvious measurement

inaccuracies occur which prevent further
measurement by the pressure module

Safety Regulations

The use of the 700PEx pressure modules meets the
requirements of the regulations providing that the user
observes and applies the requirements as laid down in the
regulations and that incorrect use of the unit is avoided. Use
must be restricted to the specified application parameters.

Protecting Yourself from Pressure Releases

XW Warning

• To avoid injury due to the release of high

pressure, use only adapters and fittings
rated to withstand the appropriate pressure.
Ensure that all adapters and fittings are
securely connected.

• To avoid a violent release of pressure in a

pressurized system, slowly bleed off the
pressure before you attach or remove the
pressure module from the pressure line.

• When measuring the pressure of potentially

hazardous media, care must be taken to
minimize the possibility of leakage. Confirm
that all pressure connections are properly
sealed.

Avoiding Mechanical Damage

To avoid damaging the pressure modules, never apply more
than 10 ft.-lbf. of torque between the module fittings or
between the fittings and the body of the module. Figure 1
shows the correct way and incorrect ways to use a wrench
when applying torque to the pressure module fitting.

calibrator and select the measure pressure function.

2. Press the [ZERO] key.

3. Enter the value from the precision barometer.

Note

Low range pressure modules may be sensitive to
gravity. For best results, pressure modules 30 psi
and below should be held at the same physical
orientation from the time they are zeroed until the
measurement is complete.

Figure 1.

Avoiding Overpressure Damage

Applying pressure in excess of the burst pressure specified
on the pressure modules can destroy the pressure modules.

WCaution

Exceeding the maximum rated pressure
may affect total uncertainty. If you
suspect the module has been over
pressured, use the performance test to
check it.

Avoiding Corrosion Damage

To avoid corrosion damage, use only with specified media as
shown below:

• Isolated: any medium that is compatible with type 316

stainless steel.

• Non-Isolated: dry, non-corrosive gasses only.

Pressure Calibration Kit

The Fluke-700PCK Pressure Calibration Kit makes it
possible to calibrate pressure modules at ambient
temperature with a precision pressure calibrator better than
the module specification. A PC running Windows
required. The kit is an optional accessory available from your
distributor or Fluke.

Performance Test

If you need to check that the pressure module meets its total
uncertainty specification, use a dead weight tester or suitable
pressure calibrator. Proceed as follows to verify that a
pressure module is operating within specification:

1. Read the pressure value with no externally applied
pressure to make sure the 0% of scale is correct. When
reading the pressure, press the [ZERO] key to remove
any zero offset.

2. Connect the pressure module to a precision pressure
source.

3. Zero as described earlier in the appropriate “Zeroing”
sections.

• 700P29Ex: use only with a medium that is compatible

with Hastelloy C276 and type 316 Stainless Steel.

Recommended Measurement Technique

For best results, the modules should be pressurized to full
scale and then vented to zero pressure (atmosphere) prior to
zeroing and making measurements.

Zeroing Gage and Differential Modules

1. Connect the pressure module to the intrinsically safe
calibrator and select the measure pressure function.

2. Position the module in the same orientation for which it
will be used.

3. Vent both high and low side measurement ports to
atmosphere.

4. Press the [ZERO] key.

Zeroing Absolute Modules

1. Connect the pressure module to the intrinsically safe
calibrator and select the measure pressure function.

2. Apply a vacuum to achieve a pressure below the rated
resolution of the pressure module being zeroed.

3. Press the [ZERO] key, and enter 0.0 as the applied
pressure.

Alternative procedure if a local precision barometer is

4. Set the precision pressure source to 20% of the
pressure module’s maximum rated pressure.

5. Make sure the reading agrees with precision pressure
source value within the total uncertainty specification in
Table 2.

6. Set the precision pressure source to 40, 60, 80, and
100%. Then reverse the order from 100, 80, 60, 40, and
20% of maximum rated pressure. Repeat step 5 at each
test point.

7. If temperature sensitivity is of concern, repeat steps 1
through 5 at various controlled temperatures.

Cleaning

WCaution

• Measuring substances that

leave residue in the sensor
may cause permanent
damage to the Pressure
Module.

• Periodically wipe the Pressure

Module with a damp cloth and
mild detergent. Do not use
abrasives or solvents to clean
the Pressure Module.
