The AMETEK 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 AMETEK 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.
Configurations
There are two important factors in the selection of the proper deadweight configuration for your application: ranges and location. If you have applications for a single range of tests, then a single piston/cylinder model is a good choice. However, if you have some high pressure and some low pressure testing, the Type T is available with dual piston/ cylinder assemblies that are interchangeable and operate using the same weight set (±0.100% and ±0.025% accuracies) or utilize dedicated weight sets for each piston/cylinder assembly (±0.015% accuracy). If you have the need to use the tester in a location other than a lab, you may need a smaller and more mobile configuration. The single column configuration will be your best selection. These are available with dual piston/cylinder assemblies. For the applications where the tester will be stationary, the dual column configuration is a good choice for those needing multiple ranges. These are supplied with two piston/cylinder assemblies and both columns are installed and ready for use. A selector valve is used to determine which column is in service at any given time.
