Model Type T Hydraulic Deadweight Tester - 1

Hydraulic Deadweight Tester Accuracy to ±0.015% of Indicated reading Accuracy ±0.025 and 0.100% is also available Repeatebility ±0.005% of Indicated reading Flexible configurations to meet differing applications - single column for field use - dual column for lab use Robust construction allows for repeated daily use Proven in design and application to meet your needs Complete tester with tools, cases, and fittings Traceable certification supplied with each tester PRODUCT DESCRIPTION The M&G Type T Hydraulic Deadweight Tester offers laboratory accuracy in an instrument that is designed to withstand an industrial environment. These testers are designed to be primary pressure standards and are available in several ranges and engineering units Laboratory accuracy The M&G Type T Deadweight tester is available in ranges to 1,000 bar (15,000 psi). This robust tester has been engineered to withstand the stresses of daily operation in a manufacturing environment and still maintain its accuracy and repeatability. The Type T is constructed of 300 series stainless steel and Monel and is supplied with Buna N O-rings as a standard unit. Viton and EPT O-rings are optional. This deadweight can use a water/alcohol mix or hydraulic oils for the pressure medium.

Model T® Hydraulic Deadweight Tester FEATURES Three accuracies available These instruments are available in ±0.100%, ±0.025%, and ±0.015% of reading. The accuracy stated is the overall accuracy of the tester. The accuracy takes into account linearity, hysteresis, and repeatability. It would also account for intrinsic corrections. Site corrections are the user’s responsibility and the unit will not perform as specified without them. The testers are manufactured to either International Standard Gravity of 9.80665 m/s2 or to a user specified local gravity. Re-entrant piston / cylinders The...

Model T® Hydraulic Deadweight Tester Overhung weight carriers Another feature of Type T deadweight tester is the way that the weights are positioned on the carrier. M&G utilizes an overhung weight carrier design. This design employs a tube carrier that is positioned over the column and onto the piston driver. The center of gravity for the stack of weights is lowered, reducing side thrust and friction; which lengthens the life of the piston/ cylinder assembly. This also improves measurement accuracy. Weight carrier Deadweight piston & cylinder Instrument under test Test manifold Check valves...
