Mensor Industrial Deadweight Testers

DH-Budenberg Deadweight Testers also referred to as Pressure Balances are primary pressure standards. This means that they measure pressure directly by applying a Force over an Area; this is the definition of pressure, P=F/A. The force comes from precisely machined masses that are stacked on a precision piston that has a specific cross sectional area. The piston rotates within a cylinder and floats atop a hydraulic (oil) or pneumatic (air) fluid under pressure. This generates a stable pressure that can be applied to a pressure device being tested.

Deadweight Testers are appropriate for use when there is a need to calibrate a wide range of pressure devices. Because the accuracy is a percent of reading, a skilled operator can use a deadweight tester to calibrate a wide range of pressure devices. DH-Budenberg Deadweight testers can have an uncertainty as low as 0.008% of reading. The measurement is traceable to the National Institute of Standards and Technology (NIST).

Deadweight testers do not require a power source which makes them a good choice for remote operation. Dead weight testers are used as pressure standards in pressure calibration labs, test facilities, and field calibration.
