Fluke 729-30G Pressure Calibrator Repair
The Fluke 729-30G is an automatic pressure calibrator: it pumps to a target pressure and then fine-adjusts itself to hold that setpoint, running a full calibration sequence with minimal operator input, and documents the results. The automation is the value – and the internal pump, the control valve and the closed-loop electronics that deliver it are what need service. At 30 psi this is a low-range instrument, which changes what goes wrong with it: a given zero offset is a far larger share of full scale than it would be on a high-range unit, and the sensor is easy to damage by connecting it to a line it was never rated for.
The Fluke 729-30G is repaired at June Company by certified technicians who work on this class of instrument daily, for process calibration teams, plant instrument departments, and documenting calibration programs. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Fluke 729-30G problems we fix
- Pressure decays during a test – leaks in the manifold or seals, which defeat automatic hold entirely.
- Sensor drifted out of tolerance – corrected and verified against reference standards.
- HART communication faults – the instrument no longer talking to the transmitter.
- Documentation or data transfer failures.
- Display and battery faults.
- Will not reach or hold setpoint automatically – the closed-loop control – pump, valve and electronics diagnosed together.
- Internal pump weak or not running – the electric pump assembly, rebuilt or repaired.
FAQs
What if it turns out not to be worth repairing? We tell you that in the quote. The evaluation costs nothing and there is no obligation to proceed.
Is HART communication repairable separately? Yes. HART faults are usually isolated to the communication circuit and do not mean the calibrator itself is failing.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
