Fluke P3025 Gas Dual Deadweight Tester – Without Pump

The Fluke P3025 Gas Dual Deadweight Tester – Without Pump is available in five models. These instruments differ with regards to their pressure and vacuum ranges, as well as their measurement units. For further information regarding these models, please see the table below.

The Fluke P3025 Gas Dual Deadweight Tester can be used to calibrate pressure sensing instruments, such as transducers, transmitters, gauges and pressure switches. As this instrument is able to create both pneumatic pressure and vacuums, it can be used to calibrate instruments with ranges both within and below atmospheric pressure.

By attaching a vacuum pump or external gas supply to the /NPT female port, the user is able to generate a vacuum or pneumatic pressure. The operator may also use the high-quality needle to make fine pressure or vacuum adjustments.

With the creation of pneumatic pressure, the piston and cylinder assembly with floatation indicator will rise. To counterbalance this upward force, accurately calibrated weight masses are added to the piston. In order to determine the final pressure value, the nominal pressure values (relative to the low- or high-pressure piston) marked on each of the added weight masses are combined. For further information regarding this process, please see the video below.

In addition to including the nominal pressure value, each of the weight masses is also inscribed with the instrument’s serial number. These weight masses are constructed from series 3 non-magnetic, austenitic, stainless steel and may be stored in a robust weight case with secure locking mechanism.

The Fluke P3025 Gas Dual Deadweight Tester is also supplied with a removable lid, ensuring that it can be easily transported between work sites. In addition to this, 1/8, 1/4, 3/8, 1/2 NPT and BSP and M20 and M14 metric adapters are included with this tester. These adapters combined with the instrument's test-station design with O-rings removes the need for PTFE tape or wrenches when attaching additional instruments. The ease with which this product may be set up is improved by the inclusion of adjustable feet and a mounted spirit level, ensuring that the Fluke P3025 Gas Dual Deadweight Tester can be adjusted to accommodate for various terrains whilst maintaining its accuracy.

Adding to this product’s accuracy is its piston and cylinder assembly, it has been manufactured in accordance with the highest standards and as such includes certified accuracies traceable to international standard laboratories, such as the National Institute of Standards and Technology (NIST). This assembly has been optimised to reduce the effects of distortion and thermal coefficients whilst maintaining the deadweight tester’s stability and durability.

Finally, the Fluke P3025 Gas Dual Deadweight Tester is supplied with an ISO 17025 accredited calibration certificate. It is calibrated to standard gravity (980.665cm/s²) and has a standard accuracy of 0.015%. However; this accuracy can be improved to 0.008% via calibrating the deadweight tester in accordance with the user’s local gravity, thereby accounting for the effect of the localised, gravitational force on the weight masses.

The Fluke P3025 Gas Dual Deadweight Tester – With Pump is a versatile, easy-to-use product, optimised for accuracy. It is ideal for calibrating a number of pressure sensing instruments.
