Fluke 729 Automatic Pressure Calibrator

Overview Fluke 729 Automatic Pressure Calibrator

The Fluke 729 Automatic Pressure Calibrator is purpose-built to simplify and accelerate pressure calibration in the field. Designed for process technicians, the 729 eliminates manual pumping by using an internal electric pump that automatically generates and regulates pressure up to 150 psi (10 bar). Simply enter a target pressure, and the calibrator does the rest—quickly, accurately, and consistently.

With integrated 4–20 mA measurement and sourcing, 24 V loop power, and built-in HART communication, the Fluke 729 provides a complete solution for calibrating pressure transmitters, switches, and I/P devices in one rugged, portable instrument.

Features and Performance

- Automatic Pressure Generation & Regulation
Built-in electric pump automatically reaches and stabilizes target pressures up to 150 psi (10 bar).
- Multi-Point Automatic Calibration
Enter start/end pressures, number of test points, and tolerances—729 performs and documents the entire test automatically.
- Bright Color Graphical Display
Dual/triple-channel display clearly shows pressure, mA output, and % error, with out-of-tolerance results highlighted.
- HART Communication (Light Configuration)
Perform mA trim, applied value trim, pressure zero trim, tag changes, unit selection, and device diagnostics.
- 4–20 mA Loop Testing with 24 V Power
Measure, source, and simulate mA signals while powering transmitters without external supplies.
- Automatic Leak Compensation
Internal fine pressure control maintains stable pressure even with minor hose or fitting leaks.
- Documentation & Data Management
Automatically records results and uploads data to DPCTrack2™ Calibration Management Software.
- Field-Ready Rugged Design
Portable, drop-tested to 1 meter, and backed by a 3-year warranty.
