Flow, level & control
pressures and temperatures – place high demands on measurement technology. VEGA sensors, for example radar level transmitters, monitor hydrogen tanks that are operated under high pressure or at temperatures as low as -253 °C. They enable precise control of quantities in storage and are not affected by pressure and temperature fluctuations. Pressure sensors that can measure up to 1,000 bar play a central role in the safe handling of compressed or liquefied hydrogen.
VEGA sensors also make an important contribution in electrolysis, the key technology for producing green hydrogen. They monitor critical parameters like pressure and temperature, thus enabling efficient and stable production.
CCS: CO capture for a climate-friendly future
CO₂ capture and storage (CCS) is indispensable for reducing emissions in the chemical industry. VEGA sensors ensure that these processes run safely and efficiently.
Capture: VEGA sensors monitor the conditions in the facilities that capture CO₂ from exhaust gases and ensure maximum efficiency with their accuracy and reproducibility.
Transport: When liquefied CO₂ is transported in pipelines, the sensors continuously measure the pressure to detect leaks.
Storage: When CO₂ is stored in underground caverns or rock formations, the sensors ensure that the greenhouse gas remains safely contained.
HOW DOES MEASUREMENT TECHNOLOGY SUPPORT THE CLOSED- LOOP ECONOMY?
The closed-loop economy is geared towards using materials for as long as possible and minimising waste. To realise this, precise data on material flow, quantity and process parameters are essential. VEGA sensors play a crucial role here. In recycling plants, for example, they facilitate the precise separation of plastics, metals and glass. Level measurement ensures that the material quantities in the processing systems are optimally controlled. In chemical recycling, where plastics are broken down into their basic chemical components, VEGA sensors monitor the conditions so that the processes run efficiently and conserve resources.
Digitalisation in the closed-loop economy
A key aspect of VEGA technology is digitalisation. With the myVEGA portal technicians can analyse measurement data in

real time and thus optimise their processes. At the same time, digital integration enables predictive maintenance, which avoids unnecessary downtime and loss of resources.
Digitalisation makes it possible to make material cycles more efficient and transparent. Without reliable data, the circular economy remains a mere vision – with VEGA, it becomes a reality.
IS MEASUREMENT TECHNOLOGY ITSELF SUSTAINABLE?
Yes! Sustainability already begins during the development of the technology. VEGA builds durable, robust and repairable sensors that function reliably, even under the demanding conditions of the chemical industry.
A modular design makes it possible to replace defective components instead of the entire instrument. Spare parts remain available for years, and regular maintenance extends the service life of the sensors considerably.
With digital tools such as the digital twin, companies can monitor the condition of their instruments at all times and plan maintenance with specific results in mind. This not only saves costs, but also conserves resources.
CONCLUSION: MAKING SUSTAINABILITY MEASURABLE VEGA sensors are the key to a resource-efficient and climate-friendly chemical industry. They enable precise control of processes, reduce waste and create the basis for future technologies such as hydrogen power and CCS. At the same time, they make an important contribution to the closed- loop economy by optimising recycling processes and driving forward digitalisation.
VEGA is setting standards in Industry 4.0 with durable, sustainable and digitally networked products. Today, sustainability in the chemical industry is not just a goal but a measurable reality.
