Audion Vacuum Level Measurement (AVLM)

Verification of accurate vacuum level realized in validatable vacuum chambers

The Audion Vacuum Level measurement (AVLM) can be placed inside the vacuum chamber or connected to the measuring port of the machine with a hose. Next, the pressure readout of the machine can easily be compared with the AVLM.

The AVLM comes standard in a sturdy plastic case, which protects the device during transport and storage.

For the purpose of validation processes it is crucial to check the vacuum level of a validatable vacuum chamber regularly. It is highly recommendable to order the calibration service (KAL AVLM) together with this device.

The AVLM can be used for vacuum verification in validatable vacuum chambers.

Calibration, Verification and Validation Services

The Audion validatable packaging machines require calibration, verification and validation services on a regular basis. Audion offers a wide range of instruments and solutions enabling users to test and verify their packaging machines and seal integrity, in order to meet the high market requirements.

Available verification instruments include:

ATM (Audion Temperature Meter): to verify the seal temperature
AFMR (Audion Force Measurement Ring): to verify the seal force of a validatable industrial sealer and to adjust the sealer in accordance with the measured values (Power Sealer and MSIDV)
ASPM (Audion Seal Pressure Measurement): to verify the seal pressure realized by compressed air (vacuum chambers and Speedpack) and to adjust the machine in accordance with the measured values
AVLM (Audion Vacuum Level Measurement): to verify the vacuum pressure

Seal Integrity Test (SIT) as a service which includes:

Seal check according to ISO 11607-2 (to check intact seal for a specified seal width)
Dye penetration test according to ASTM F1929 (to check no channels or open seals)
Peel test according to EN 868-5 Annex D (to check tensile strength of seal)

Audion Factory Calibration (incl. Calibration Certificate): (Re-) calibration executed by certified engineers certifies the preciseness of the critical sealing parameters of the packaging machine. Reference standards calibrated under ISO17025 accreditation
IQ/OQ Check:

- Installation Qualification (IQ): an Audion service engineer inspects the packaging machine in your operating environment, checking the following aspects: correct installation, functionality, specifications, critical process parameters and documents. Includes training & certificate.
- Operational Qualification (OQ): an Audion engineer tests and will register seal integrity of your bag(s) in a test plan. Includes determination of sealing parameters, tolerances, acceptable criteria and worst case testing.
