Automatic Vacuum Calibration System
June 1, 2014
AVCS-3SD from Potomac Electric Corporation features a fully automatic pressure and process flow control, as well as data acquisition, from 1.3x10-3 to 1.3x10+5 Pa (1x10-5 to 1000 Torr) with enhanced accuracy.
The pressure control algorithm, integrated controls, calibration and data analysis software are intended to provide a cost effective approach to calibration of vacuum gauges that is NIST traceable, fast and repeatable. AVCS-3DS allows user to develop, store and recall multiple process recipes for each gauge or for a group of gauges and, according to the company, will consistently follow the selected calibration protocol. A built in calibration process log file, in addition to data and process security, provides users with complete supervisory oversight of each process step. AVCS-3SD is fully compliant with ISO 3567.
The system has three process modes and a service mode:
- Automatic mode - Auto selection of set points based on the number of set points per decade. Automatic processing from lowest to highest pressure.
- Semi-automatic mode - Manual entry of set points prior to test. Automatic processing from lowest to highest pressure.
- Manual mode - Manual set point entry (one at a time) with automatic pressure and process control. Each consecutive set point can be set higher or lower than the previous one.
- Service Mode - Manual control of all valves and controllers. Beneficial for step by step system calibration and troubleshooting.
