Deadweight Tester Accessories

Fluke Calibration provides the complete solution for pressure calibration using a deadweight tester, including accessories for test media separation, dirt / moisture traps, dial gauge pointer removers, angle adapters, and two gauge test stands.

P5521 and P5522 Liquid-to-Liquid Separators

These liquid-to-liquid separators connect directly to the test port of a hydraulic deadweight tester or comparison test pump. A flexible diaphragm separates the fluids, protecting the calibrator from contamination, and allows calibration of the device in its specific working fluid.

P5521-For pressures to 10,000 psi (700 bar)
P5522-For pressures to 7,000 psi (480 bar) for Skydrol or other aggressive fluids

P5523 Liquid-to-Gas Media Separator

Pressure range 0 to 3,000 psi (210 bar)

For high pressure pneumatic calibrations this unit interfaces with hydraulic deadweight testers providing a rateless liquid-to-gas separation. Driven by a pneumatic pressure source (nitrogen bottle) and controlled by needle valves, high pressure gas is balanced against the liquid in a hydraulic deadweight tester through a series of fluid traps.

* Note---since fluid mist may be transferred during operation we do not recommend this device for oxygen safe instruments using an oil operated deadweight tester

P5531 Dirt / Moisture Trap

Pressure range 0 to 500 psi (35 bar)

Dirt / moisture traps provide an effective barrier against the transfer of moisture and dirt from an instrument under test to the sensitive piston/cylinder assembly of a pneumatic deadweight tester. Unexpected particle contamination or fluid inside the device under test will be prevented from entering the deadweight system, avoiding downtime for maintenance or repair. Designed for operation in the vertical position these traps are simple to dismantle and easy to clean.

Designed to mount directly on the deadweight tester and featuring an acrylic chamber for visibility of contaminates this unit utilizes the standard test port adapters for easy instrument connections.

P5532 Dirt / Moisture Trap

Pressure range 0 to 3,000 psi (210 bar)

Dirt / moisture traps provide an effective barrier against the transfer of moisture and dirt from an instrument under test to the sensitive piston/cylinder assembly of a pneumatic deadweight tester. Unexpected particle contamination or fluid inside the device under test will be prevented from entering the deadweight system, avoiding downtime for maintenance or repair. Designed for operation in the vertical position these traps are simple to dismantle and easy to clean.

This high pressure version is provided with an aluminum central chamber for safety and utilizes the standard test port adapters.

P5540, P5541, and P5542 Adapter Sets

These thread adapters come in metric, BSP & NPT sizes to help you make connections with Fluke P5500 series hydraulic and pneumatic comparison test pumps, media separators & accessories.

P5540 Metric

M14 x 1.5, M20 x 1.5, 1/8 and 1/4 BSP

P5541 BSP

1/8, 1/4, 3/8 and 1/2 BSP

P5542 NPT

1/8, 1/4, 3/8 and 1/2 NPT

P5543 Angle Adapter

To calibrate gauges with the pressure connection on the rear (for example, panel mount gauges) in their correct operating position, an angle adaptor should be used. The angle adapter uses the standard gauge adapters and positions the gauges at 90º. The maximum working pressure of this unit is 10,000 psi (700 bar).

P5544 Two Gauge Stand

This adapter mounts directly to the test port of the calibrator and allows for the calibration of two instruments at the same time, or the connection of a reference test instrument. Maximum working pressure is 10,000 psi (700 bar).
