Super User Budenberg Pneumatic Dead Weight Testers Check out our available range of Budenberg Pneumatic Dead Weight Testers. BGP1 15 to 1000 mbar / 1.5 to 100 kPa The BGP1 has a 1/2in2 high chrome steel piston/cylinder unit. The design has been proven over many years to provide excellent sensitivity and stability. Low start pressure is achieved through use of a hollow piston and aluminium head. LEARN MORE BGP7 0.1 to 7 bar / 10 to 700 kPa The BGP7 has a 0.5in2 high chrome steel piston/cylinder unit which operates on pure Gas. The design has been proven over many years to achieve the necessary sensitivity whilst remaining robust enough for heavy industrial use. LEARN MORE BGP25 0.2 to 25 bar / 20 to 2500 kPa The BGP25 has a 1/8in2 tungsten carbide piston/cylinder unit which combined with an overhung austenitic mass set to produce a range of 0.2 to 25 bar. The free deformation psiton makes the unit good for high accuracy measurement. LEARN MORE BGP120 1 to 120 bar / 100 to 12000kPa The BGP120 is an oil lubricated gas operated piston cylinder unit. If required an inert fluid (such as Fomblin) can be used instead of the oil to provide lubrication without contamination of Gas with hydrocarbon vapour. LEARN MORE BGP1P 15 to 1000 mbar / 1.5 to 100 kPa The BGP1P has a 1/2in2 high crhome steel piston/cylinder unit. The design has been proven over many years to provide excellent sensitivity and stability. Low start pressure is achived through use of a hollow piston and aluminium head. LEARN MORE
