Fluke Calibration 729 is an automatic pressure calibrator designed to simplify pressure transmitter, pressure switch and process instrument calibration in the field and laboratory. With an integrated electric pump, automatic pressure generation and regulation, HART communication, 4–20 mA measurement and sourcing, and automatic documentation of calibration results, the Fluke 729 combines several essential calibration functions in one rugged portable instrument.

Instead of manually generating and fine-adjusting pressure at every calibration point, technicians can enter the required target pressure directly into the calibrator. The integrated electric pump automatically generates the pressure, while the internal fine adjustment system stabilizes it at the requested setpoint.

The Fluke Calibration 729 is available in three main pressure ranges: 30 psi (2 bar), 150 psi (10 bar) and 300 psi (20 bar). All standard versions can also generate negative gauge pressure down to approximately −12 psi or −0.83 bar.

With a one-year pressure specification of 0.02 % of full scale and pressure control capability specified at a minimum of 0.005 % of full scale, the 729 is designed for accurate and repeatable process calibration.

Integrated HART communication allows technicians to work with smart pressure transmitters without requiring a separate HART communicator for many common calibration tasks. The calibrator can also measure, source and simulate 4–20 mA signals and provide 24 V loop power.

At europascal, we offer professional solutions for pressure and electrical calibration. In addition to the Fluke Calibration 729, our portfolio includes pressure controllers, digital pressure gauges, reference standards, pressure pumps and multifunction process calibrators.

Ideal for Demanding Calibration Applications

The Fluke Calibration 729 was specifically developed to make process pressure calibration faster and easier.

Conventional field pressure calibration often requires several separate instruments and numerous manual steps. A technician may need a pressure pump, reference pressure gauge, electrical calibrator and HART communicator.

The Fluke 729 combines many of these functions in one portable instrument.

Typical applications include:

• Pressure transmitter calibration
• Smart HART transmitter calibration
• Pressure switch testing
• 4–20 mA loop testing
• Process instrument maintenance
• Factory calibration
• Field calibration
• Quality assurance
• Preventive maintenance
• Troubleshooting
• Process plant maintenance
• Instrument commissioning

This makes the 729 particularly useful for process technicians who regularly calibrate pressure instruments directly in the field.

Automatic Pressure Generation

One of the key advantages of the Fluke Calibration 729 is its integrated electric pressure pump.

The operator enters the desired target pressure and the calibrator automatically generates the required pressure.

This eliminates much of the manual pumping normally associated with portable pressure calibration.

Automatic pressure generation is particularly useful during repetitive calibration procedures involving several measurement points.

Instead of manually approaching every calibration point, the technician can concentrate on the calibration procedure and evaluation of the device under test.

Automatic Pressure Regulation

Generating pressure is only one part of a calibration procedure. The pressure must also remain sufficiently stable for a reliable measurement.

The Fluke Calibration 729 therefore incorporates automatic fine pressure control.

After the internal pump approaches the requested setpoint, the fine adjustment system automatically stabilizes the pressure at the target value.

The system can also compensate for small leaks in hoses and test setups.

This reduces the need for repeated manual pressure adjustment and helps provide stable measurements during calibration.

Three Pressure Ranges

The Fluke Calibration 729 is available in three primary pressure ranges.

Fluke 729 30G

Pressure range:

−12 to 30 psi

approximately:

−0.83 to 2.07 bar

Fluke 729 150G

Pressure range:

−12 to 150 psi

approximately:

−0.83 to 10.34 bar

Fluke 729 300G

Pressure range:

−12 to 300 psi

approximately:

−0.83 to 20.68 bar

This allows users to select the version that best matches the pressure range of their process instrumentation.

Pressure Accuracy and Control

The Fluke Calibration 729 provides a one-year pressure specification of:

0.02 % of full scale

The pressure control specification is:

0.005 % of full scale minimum

The combination of accurate pressure measurement and automatic control makes the 729 particularly useful for pressure transmitter calibration.

For applications outside the range or accuracy capabilities of the internal pressure system, compatible external Fluke pressure modules can extend the available measurement capabilities.

Automatic Multipoint Calibration

The Fluke Calibration 729 can automate multipoint pressure calibration.

The technician can define the starting pressure, ending pressure, number of test points and tolerance requirements.

The calibrator then automatically steps through the defined pressure points and documents the test results.

This significantly reduces repetitive manual work.

Automated procedures also help technicians perform recurring calibrations in a consistent manner.

This is particularly useful when many similar pressure transmitters or switches need to be tested according to standardized procedures.

Automatic Documentation

Documentation is an important part of professional calibration and maintenance.

The Fluke Calibration 729 can automatically document test results during calibration.

Instead of manually recording every pressure and electrical measurement value, the technician can use the calibrator’s documentation capabilities.

Calibration results can subsequently be transferred and managed using compatible calibration management software.

The Fluke 729 supports DPCTrack2 Calibration Management Software, which can be used to manage instrumentation, scheduled tests, calibration data and reports.

Integrated HART Communication

Modern process pressure transmitters frequently use the HART communication protocol.

The Fluke Calibration 729 includes built-in HART communication capabilities.

This allows technicians to perform common HART transmitter tasks without requiring a separate communicator for many routine applications.

Supported functions include transmitter mA adjustments, basic HART configuration, diagnostics and adjustment to applied 0 % and 100 % pressure values.

The combination of pressure generation, electrical measurement and HART communication makes the 729 particularly suitable for smart pressure transmitter calibration.

Measure, Source and Simulate 4–20 mA

The Fluke Calibration 729 provides comprehensive current loop functionality.

It can:

• Measure current
• Source current
• Simulate current

The available range is:

0 to 24 mA

with a resolution of:

1 µA

This allows the calibrator to test and troubleshoot conventional 4–20 mA process loops.

The electrical measurement accuracy is specified at 0.01 % ±2 least significant digits under the specified reference conditions.

24 V Loop Power

Many process transmitters require an external supply voltage during calibration.

The Fluke Calibration 729 provides integrated loop power, reducing the need for a separate external power supply.

Loop compliance voltage is:

24 V DC at 20 mA

This makes it possible to power many common two-wire pressure transmitters directly during calibration.

The combination of pressure generation, electrical measurement and loop power simplifies field calibration setups.

DC Voltage Measurement

In addition to current measurement, the Fluke 729 can measure DC voltage.

The measurement range is:

0 to 30 V DC

with a resolution of:

1 mV

This provides additional flexibility when testing pressure transmitters, sensors and process instrumentation with voltage outputs.

Pressure Switch Testing

Pressure switches require determination of the pressure at which the electrical switching state changes.

The Fluke Calibration 729 can automatically generate and control the required pressure while monitoring the switching event.

This makes it possible to perform pressure switch tests without manually adjusting pressure using a separate hand pump.

Pressure switch testing is particularly useful in maintenance, safety systems and process control applications.

External Fluke 750 Series Pressure Modules

The capabilities of the Fluke Calibration 729 can be expanded using compatible Fluke 750 Series Pressure Modules.

Fluke offers numerous external pressure modules covering additional pressure ranges and pressure types.

External modules can be particularly useful when:

• A pressure range outside the internal pump range is required
• Higher resolution is needed at low pressures
• A different pressure type is required
• Additional calibration flexibility is needed

This makes the 729 more versatile than a calibrator limited exclusively to its integrated pressure sensor.

Optional Temperature Measurement

With the optional Fluke 720RTD probe, the Fluke 729 can also measure temperature.

The Pt100 measurement range extends from:

−50 °C to +150 °C

with a temperature resolution of:

0.01 °C

This capability is useful in applications where pressure calibration needs to be supplemented by temperature measurement.

Fluke Connect Models

The Fluke Calibration 729 is also available in FC versions with wireless communication for Fluke Connect.

Available wireless models include:

• 729 30G FC
• 729 150G FC
• 729 300G FC

The standard 30G, 150G and 300G versions do not include this wireless communication function.

This allows users to select the version that best matches their connectivity requirements.

Rugged Portable Design

The Fluke 729 was developed for field instrumentation work.

Its enclosure provides IP54 protection, and Fluke specifies the instrument as tested to withstand a 1-meter drop.

The calibrator weighs approximately:

2.95 kg

Its compact portable construction, rechargeable battery and supplied carrying case make it suitable for use throughout industrial facilities.
