Automatic pressure testing and documentation of calibrations

August 2017 Maintenance, Test & Measurement, Calibration

Pressure instrument calibration is a significant part of the maintenance workload in process plants and requires a high level of accuracy and repeatability. Fluke has recently 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 729, technicians simply input a target pressure and the calibrator automatically pumps to the desired set-point while the internal fine adjustment control stabilises the pressure at the requested value, delivering more accurate results and speeding the calibration process. Other features include:

• Automatic pressure generation and control for multiple tests to 20 bar. Fill in a test template and the 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 colour 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 24 V 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 729 allows technicians remote monitoring of 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 manage instrumentation, create schedule tests and reports and organise calibration data.
