The Ametek T101C Hydraulic Deadweight Tester, 10-1000 psi, 0.025% Accuracy offers laboratory accuracy in an instrument that is designed to withstand an industrial environment. These testers are designed to be primary pressure standards. This model offers a range up to 1000 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. This deadweight can use a water/alcohol mix or hydraulic oils for the pressure medium.

The T10-1/C is available in ±0.025% of reading. The accuracy stated is the over-all 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 International Standard Gravity of 9.80665 m/s2. The T101C employs a re-entrant type piston/cylinder assembly. This design applies test fluid to the outside and inside of the cylinder. Unlike a simple piston/cylinder, this configuration reduces clearance between the piston and cylinder as pressure increases. This reduces the rate of fluid leakage and increases float time, offers the technician more time for testing, and reduces the amount of pumping necessary to sustain the fluid loss.
