Fast and accurate automatic pressure testing and documentation of critical regulatory and compliance calibrations

Pressure instrument calibration is a significant part of the maintenance workload in process plants that requires a high level of accuracy and repeatability. Fluke has just launched the new Fluke 729 Automatic Pressure Calibrator - simplifying the calibration process by automating pumping to the precise test pressure, improving calibration integrity by compensating for minor leaks, and automatically documenting the pressure calibration process to meet compliance and regulatory requirements. 

With the rugged, portable Fluke 729, technicians simply input a target pressure and the calibrator automatically pumps to the desired set-point while the internal fine adjustment control stabilizes the pressure at the requested value, delivering more accurate results and speeding the calibration process. 

Fluke 729 Automatic Pressure Calibrator features: 

• Automatic pressure generation and control for multiple tests to 300 psi, (20 bar, 2 MPa). Fill in a test template and the Fluke 729 automatically pumps to and documents a multiple-point pressure calibration test.
• Easy calibration documentation using defined templates for transmitters and switches. Input the starting and ending test pressures and number of test points and the calibrator documents the applied pressure, measured mA, and percentage error for each test point. The bright color graphical display flags out of tolerance test results in red.
• HART communication enabling mA output trim, trim to applied values, and pressure zero trimming of HART pressure transmitters. Technicians can also perform light configuration tasks such as changing a transmitter tag, measurement units, and ranging.
• Measurement of mA signals on transmitter outputs and sourcing and simulation of mA signals for testing I/Ps and other mA loop devices. It includes a 24V loop power supply for testing and powering transmitters in standalone tests disconnected from the control system.

As part of the Fluke Connect® reliability platform, the Fluke 729 allows technicians to remotely monitor calibrations using the Fluke Connect mobile app as well as manage, store, and share pressure measurements and logging events. 

Documented calibration results can be uploaded to the included DPCTrack2™ Calibration Management Software, to easily manage instrumentation, create schedule tests and reports, and organise calibration data.
