Users Easily Identify Vacuum Leakage with Thyracont’s VD85

Manufacturers and users of vacuum pumps, components and systems have reason to celebrate the arrival of the new series of compact vacuum instruments from Thyracont. The latest generation of these useful digital meters now includes a data logging capability that truly sets them apart from all other vacuum measurement instrument. The VD85 instrument; in combination with Thyracont’s VacuGraphTM 8.0 software puts a highly practical and functional tool into the hands of quality assurance, equipment maintenance and field service engineers.

The VD85 instrument can be operated from either its internal battery or from an external power supply. The instrument is attached to the test article with a standard KF vacuum flange. Integrated precision sensors provide a seamless measurement range from 1200 mbar to 5x10-4 mbar (900 Torr to 5x10-4 Torr). The measured pressure is displayed and can be downloaded to the internal data logger, where up to 2000 continuous data points can be stored.

A new (patent pending) firmware feature “Store only at pressure change”, allows the user to have the instrument log data points only if the pressure has changed since the last measurement. This capability conserves data storage space within the VD85. In use, the instrument will record rapid pressure changes (as in the case of a pump down from atmospheric pressure). When the pressure reaches equilibrium, the instrument responds by not taking duplicate measurements.

The VD85 USB port enables the user to download stored measurement data to a computer operating Thyracont’s VacuGraph 8.0 software. Amongst other features, this powerful analysis software provides a logarithmic display of pressure. A key feature of VacuGraph 8.0 is Leak Rate Calculation (patent pending). The VD85 can be used to determine the leak rate of a closed volume. When the instrument has recorded a pressure increase and the data downloaded to VacuGraph 8.0, the user simply enters the volume of the test article and identifies two points on the log display of pressure. The software will automatically calculate the leak rate.

Thyracont Vacuum Instruments GmbH is located in Germany and manufactures precision vacuum measurement and control units for application in rough to ultra high vacuum. Its customers include equipment manufacturers, industrial users, and research laboratories.
