Product Description of Fluke 729
The Fluke 729 Automatic Pressure Calibrator is a portable pressure calibration device designed specifically for process technicians to streamline pressure calibration workflows and enhance testing efficiency. Its core advantage lies in its built-in electric pump, which enables automatic pressure generation and regulation. Users only need to input the target pressure value, and the device automatically pressurizes to the setpoint while stabilizing the pressure, eliminating the tedious manual pumping and fine-tuning required by traditional methods. The Fluke 729 supports a pressure range of up to 300 psi (20 bar/2 MPa) and offers three range variants (30 psi, 150 psi, 300 psi) to accommodate diverse industrial applications. Additionally, it integrates HART communication protocol, enabling zero-point correction, parameter configuration, and fault diagnostics for smart transmitters. The included 24V loop power supply allows independent powering of tested transmitters, further simplifying the testing process. With a rugged portable design that passes 1-meter drop tests and a semi-hard carrying case for storing test hoses, connectors, and accessories, the Fluke 729 is ideally suited for demanding field operations.
Key Features
High-Precision Pressure Control and Generation
Supports a pressure range of 0–300 psi (20 bar/2 MPa) with an accuracy of 0.02% of full scale and a control resolution as fine as 0.005% of full scale, ensuring reliable calibration results.
Automated Calibration Workflow
The built-in electric pump automates pressurization and stabilization. Users input start/end pressures and test point quantities via onboard test templates, and the device autonomously completes multi-point pressure testing and data logging, significantly reducing calibration time.
HART Communication and Smart Transmitter Support
Integrates HART protocol for mA output adjustment, zero-point correction, range configuration, and device diagnostics data retrieval for pressure transmitters. Compatible with the latest HART 7 version to meet smart instrument calibration needs.
Multi-Parameter Measurement and Signal Simulation
Simultaneously measures and outputs 4–20 mA current signals, supporting testing of I/P converters and other loop devices. The included 24V loop power supply independently powers tested transmitters. An optional 720RTD probe enables temperature measurement for expanded applications.
Data Management and Remote Monitoring
Supports uploading test results to DPCTrack2 calibration management software for standardized reporting and calibration history tracking. Compatible with the Fluke Connect application for wireless remote monitoring, data storage, and event logging, enhancing team collaboration.
Rugged Design and User-Friendly Features
Passes IP52 protection rating and 1-meter drop tests for harsh industrial environments. Equipped with a 3.5-inch color graphical display supporting dual/triple-channel data visualization, with out-of-tolerance values highlighted in red. Offers a 3-year standard warranty to reduce long-term costs.
