Vacuum gauge calibration systems
Process reliability requires checks, adjustments and recalibration of vacuum gauges and sensors at regular intervals.
Setting devices to an initial value is an important component of quality assurance. Calibrated gauges are particularly used where high requirements are made on reproducibility and compatibility as well as on the quality of testing processes. Also, if a clear reference is required for lots of existing pressure measurement devices, calibration is a must.
The CS calibration systems enable you to check and calibrate your vacuum gauges to the defined and required measurement accuracy. This can follow the standards of the German Accreditation Body (DAkkS) or any international standard, whereas the required measurement accuracy must be defined by the users.
In this context the...
We have been calibrating all makes of gauges and sensors independently for customers since 1981.
A DAkkS or factory calibration certificate is issued for the calibration process. Devices with inadequate long-term stability or for measurement principles which are unsuitable for calibration cannot be calibrated.
Calibration can be conducted in static or dynamic mode.
- Static means the calibration chamber is isolated from the pump system and gas is admitted until the desired pressure value is reached. This method requires a low outgassing rate, which is achieved by a clean calibration chamber and an extensive pumping time.
- Using dynamic calibration, the chamber pressure is adjusted by means of a gas dosing valve and a throttling valve on the turbo-molecular pump intake. The inlet gas quantity is manually balanced with the pumped gas flow to set a stable pressure.
CS 3
- Vacuum gauges and measurement systems of any make may be calibrated
- Designed in accordance with ISO 3567
- Transfer standards with PTB-, DAkkS- or factory certificate
- Easier DIN / ISO 9000 approval
- Reliable and reproducible measurements
- Quick start-up
- Measurement system free of hydrocarbons through the utilization of dry compressing vacuum pumps
- Simple operation
- CE approval
The base unit of the CS 3 mainly consists of a stainless-steel calibration chamber (design in accordance with ISO 3567) with three calibration ports and a dry compressing Turbo-molecular pump system TURBOLAB 90. For pressure setting a manual gas dosing valve is used in combination with a butterfly valve for throttling the suction speed. A full range high vacuum gauge is fitted to...
