FAQ – Frequently Asked Questions About Vacuum Measuring Instruments
Here you will find answers to the most common questions regarding our vacuum measuring instruments. If you need further information, please do not hesitate to contact us.
What is a vacuum gauge?
A vacuum gauge measures the pressure within a vacuum system. It converts the physical pressure into an electrical signal that can be used for process control or data logging
What measurement principles are available?
The most common principles are Pirani measurement (determines the thermal conductivity of the gas) and ionization measurement (detects the ion current within an enclosed electron path). ULVAC offers both types — Pirani sensors are ideal for medium to high vacuum ranges, while ionization gauges are suitable for ultra-high vacuum applications.
What measurement ranges do the instruments cover?
ULVAC vacuum gauges typically measure pressures from approximately 10⁵ Pa (atmospheric pressure) down to 10⁻⁸ Pa and below. Depending on the model, specialized sensors are available for different sub-ranges.
Do vacuum gauges need to be calibrated?
Yes. To maintain long-term accuracy, vacuum gauges should be calibrated regularly — typically once a year or according to your process requirements. ULVAC provides certified calibration services to ensure your measurements remain precise.
How easy are the vacuum gauges to operate — and do you offer training?
Our vacuum gauges are designed for intuitive operation. To ensure your team can make full use of the equipment’s capabilities, ULVAC offers comprehensive training programs. Our experts provide practical guidance on installation, operation, maintenance, and calibration, enabling you to achieve reliable measurement results right from the start
