US Fluke Deadweight Tester Selection Guide
The deadweight tester (DWT) is a very robust and flexible pressure measurement standard. This selection guide is intended to simplify the process of selecting the right deadweight tester for your application. Click on the individual products to get detailed specifications and pricing.
Adapters
A DWT will include a test port to allow for the connection of the unit under test. Since one of the inherent features of a DWT is its flexibility, it is important that the test port connection be adaptable to multiple types of pressure devices.
The test port on a Fluke Calibration DWT is available with adapters for various sizes. The different kits that can be selected are:
- 1/8, ¼, 3/8, ½ BSP (British Standard Pipe)
- 1/8, ¼, 3/8, ½ NPT (National Pipe Thread)
- M14 x 1.5, M20 x 1.5, 1/8 and ¼ BSP
When ordering, one of the above sets can be selected. If additional sets are required, they can be purchased as separate line items.
Due to the unique design of the Fluke Calibration test port, all of the above adapters are capable of providing leak tight seals to 140 MPa (20,000 psi) without the use of wrenches or PTFE tape.
