For over half a century, VEGA has earned the trust of business partners across diverse industries worldwide through its expertise in pressure instrumentation. Renowned for innovative, reliable pressure transmitters, VEGA empowers seamless integration into any process while delivering the high performance that industries demand.
VEGA develops all core technologies in-house and manufactures the main components of its measuring instruments. This also applies to the ceramic-capacitive CERTEC® and the metallic METEC® measuring cells.
They are produced under “Clean Room Class 100” conditions to ensure that they deliver unrivalled precision. Each one is calibrated on DKD-certified test benches – the calibration certificate is an integral part of the scope of delivery.
Ceramic Measuring Cell CERTEC®
The ceramic measuring cell CERTEC® features a sensor element with a flush-mounted, abrasion-resistant ceramic diaphragm. It is engineered to handle measuring ranges from -1 up to +100 bar, and it is also available in a compact version capable of detecting pressures as low as 25 mbar.
Designed for versatility, it operates reliably in temperatures between -40 and +150 °C.
As a dry measuring cell, it offers excellent long-term stability and is highly resistant to both overload and abrasion.
Its design ensures it is completely front flush, and it provides front-flush temperature measurement as well as integrated diaphragm rupture detection, enhancing both the safety and accuracy of measurement operations.
Metallic Measuring Cells
Among the types of metallic measuring cells available are the Metallic METEC® measuring cell, the piezoresistive metallic measuring cell, and the metallic thin-film measuring cell.
Each variant offers specific advantages suited to different measurement applications and operational requirements.
The measuring system offers a wide range, spanning from -1 to +1000 bar, and is capable of operating within a temperature range of -40 to +200 °C.
Designed without any elastomers, it is completely vacuum-proof and demonstrates excellent thermal shock resistance.
The system is unaffected by condensation and remains highly resistant to both vibration and shock, ensuring reliable performance even in demanding environments.
Chemical Seal
Chemical seal systems consist of a separated process diaphragm and an intermediate transmission fluid. These systems offer a measuring range from -1 to +1,000 bar and can operate within a broad temperature span, from -90 to +400 °C.
The wetted parts are typically made from high-grade materials such as stainless steel 316L, tantalum, or Hastelloy, while the diaphragms themselves can be coated with materials like polyamide (PA), polypropylene (PP), or gold to meet specific application requirements.
Differential Pressure Measuring Cell
The differential pressure measuring cell utilises a piezoresistive metallic measuring cell that features an integrated overload diaphragm.
This advanced design supports measuring ranges from as low as 0.01 bar up to 40 bar, while operating reliably within a temperature span of -40 to +105 °C.
Notably, the measuring cell is dynamically overload-proof up to +400 bar, ensuring excellent durability even under extreme conditions.
Additionally, the system allows for the attachment of a chemical seal, further enhancing its versatility for various industrial applications.
Getting it Right from Plant to Pipeline
These sensors set the standard for accuracy, broad pressure ranges, and certified hygiene, remaining steadfast even under the harshest conditions—whether facing wear, aggressive chemicals, soaring temperatures, humidity, or diffusion.
From concept to completed product, every VEGA pressure sensor is manufactured with state-of-the-art, environmentally conscious technology, reflecting a commitment to quality at every stage.
