Fluke 7250 Pressure Controller Repair

Pressure calibrators come back to us for one of two reasons: the pressure side has stopped behaving, or the electrical side has. Knowing which before you ship saves a step. FlukeMeterRepair.com works on Fluke instruments and nothing else, which means the Fluke 7250 Pressure Controller is not an unfamiliar model to us.

Symptoms we see on the Fluke 7250 Pressure Controller

• Readings disagree with your reference – sensor drift, which is correctable.
• The mA reading is wrong but pressure looks fine – the electrical side, independent of the pressure side.
• It reads something other than zero with nothing connected.
• Nothing on the display, or the keypad has stopped responding.
• It builds pressure then bleeds straight back down – seals and O-rings, the single most common pressure calibrator repair and rarely the sensor.
• The pump works but never reaches the number you want – usually a leak somewhere in the manifold rather than a tired pump.

What the repair involves

We pressure-test the whole path first, because a leak and a failed sensor look identical from the front panel. Seals and O-rings are replaced as a set rather than individually, the sensor is checked against a reference across its range, and the mA loop is verified separately from the pressure measurement. Everything is repaired at component level rather than by swapping assemblies, and the measured results come back with the instrument.

Before you ship it

Send the hoses and fittings you normally use with it. A surprising number of apparent instrument faults turn out to be a leaking test hose, and we cannot rule that out without them.
