Fluke 718Ex Pressure Calibrator Repair
The Fluke 718Ex is a pressure calibrator with an integrated hand pump – the pump, the sensor and the mA loop electronics all live in one handheld body, which is what makes it a genuinely one-handed field tool and also what gives it a failure mode the pumpless models do not have. The Fluke 718Ex is an intrinsically safe variant, rated for use in hazardous areas, and its protection circuitry is verified as part of the repair.
June Company’s certified technicians repair the Fluke 718Ex for process technicians, refinery and plant instrument crews, and field calibration teams. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Fluke 718Ex problems we fix
- Pump will not build or hold pressure – worn pump seals and O-rings, the single most common 718 repair.
- Slow pressure decay – a leak in the pump body, manifold or fittings – the unit builds pressure then bleeds off.
- Vacuum side not pulling – the pump’s vacuum path specifically, which often fails while the pressure side still works.
- Pressure readings drifted out of tolerance – sensor drift, corrected and verified.
- mA loop or 24V supply faults.
- Fine-adjust vernier seized – the adjustment screw no longer trimming pressure smoothly.
- Intrinsic safety barrier faults – the protection circuitry that makes this model suitable for hazardous areas, tested as part of every repair.
FAQs
Do you document the results? Yes. The measured results are recorded and returned with the instrument.
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.
