The liquid lubricated range of high pressure deadweight testers feature an oil lubricated piston / cylinder assembly, this ensures performance and makes the tester less susceptible to performance issues caused by contamination.
Gas is transferred to the system via the controls and as this acts directly on the surface of the oil, the transfer of pressure within the system is rate-less.
These deadweight testers can be specifically calibrated to local gravity, at no extra cost. This is because gravity varies and has a direct effect on the force of the weights, which in turn can affect the accuracy. If not specified, the standard gravity is set to 980.665 cm/s2.
The optional PressCal software, a windows based program that allows for the entry of necessary corrections to enhance the performance of the deadweight tester. The calibration details are stored and used to create a calibration certificate. Using the software, the accuracy improves to 0.008%.
Key features include:
Accuracy better than 0.015% of reading (improved to 0.008% with PressCal software)
Different pressure units available
Built-in pneumatic hand pump
High quality needle valve for optimum control
O-Ring design eliminates the need for wrenches or PTFE tape
