VMS2SA (Standard Accuracy) is an entry level model from a new family of calibration systems developed by Vacuum Metrology Systems. VMS2 family design builds on experience and customer feedback gained during development and production of our AVCS system.
VMS2SA is a truly portable and cost effective fully automatic calibration system onsite calibration of vacuum gauges. In addition to portability and accuracy, VMS2SA offers a built in Calibration Management Software suite to ensure compliance with ISO 90XX, ISO/IEC 17025, ANSI Z540 and other industry specific quality standards.
The system utilizes up to 3 NIST or PTB traceable vacuum transfer standard with basic accuracy of up to .25%. The standards coverage can be custom configured to provide the best accuracy throughout the required calibration pressure range. The proprietary pressure control algorithm allows for the repeatable control resolution of up to 0.1% of the set point.
VMS2SA system is fully compatible with the requirements of ISO-3567.
Similar to all of our systems, VMS2SA can be configured to utilize the Standards that your company already own.

2 Standards: 100T and 10T with Basic Accuracy of ±0.25%
0…10 VDC input for UUTs for Automatic data collection
RS232/485 Inputs for UUTs
The System will be pre-configured to use your own 1000T, 100T and 1T standards with
Basic Accuracy of ±0.12%.
Manual data input for all UUT types
0…10 VDC Inputs for UUTs (Option “A”):
The System will capture readings from gauges with 0…10 VDC full scale analog outputs. This will cover most of the Capacitance Manometers (a.k.a. Capacitance Diaphragm Gauges). The option may be used along with the optional ±15 VDC linear power supply (see below).
±15 VDC linear power supply (Option “P”):
The power supply will provide the required power to up to 3 Capacitance Manometers without the need for an external controllers/power supplies.
4…20 mA Inputs for UUTs (Option “C”):
The System will capture readings from gauges with 4…20 mA full scale analog output.
RS232/485 Inputs for UUTs (Option “R”):
The System will capture readings from gauges with RS232/485 output. Additional RS232/485 commands, such as Zeroing, can be programmed to be processed automatically as well.
Manual Data Input (Option “M”):
The System will be configured for the manual data input for all UUT types
