Precision and efficiency in focus – The new AVS701 from E+E Elektronik

Developed and designed for demanding industrial applications, the new AVS701 from E+E Elektronik sets new standards in air and gas flow velocity measurement. Maximum efficiency and process reliability are achieved through highly accurate measurements, easy installation enabled by precise sensor positioning, and an integrated process gas library. An optional external pressure sensor compensates for changes in ambient pressure. Equipped with a robust ceramic sensing element featuring a special coating and a stainless-steel probe head, the sensor ensures highly precise results even under extreme or corrosive conditions.

Visually and technically redesigned, the air and gas velocity sensor delivers top performance in accuracy and reliability while offering significantly simpler installation. It is optimized for demanding industrial applications within a measuring range of 0 to 40 m/s and –40 to +140 °C. Its versatility makes it suitable for a broad spectrum of uses—from pharmaceutical production to process monitoring in 3D printers. Increased efficiency in process costs and up to 60% faster installation make the AVS701 the best choice in its performance class.

Thanks to a specially developed alignment crimp for the remote probe, the AVS701 can be precisely positioned relative to the flow direction using the supplied alignment tool. This precise alignment reduces installation-related errors and ensures accurate measurement results, speeding up commissioning and significantly improving efficiency.

Optimal product quality through highest measurement accuracy
The AVS701 offers exceptional measurement accuracy of ±1% of the measured value, and even ±0.03 m/s in the 0–2 m/s range. This precision ensures high process reliability, which is crucial in sensitive environments such as cleanrooms and pharmaceutical production. Highly accurate monitoring of airflow improves product quality and reduces waste. Process deviations can be detected more reliably and prevented at an early stage. The long-term stability of the AVS701 also reduces maintenance requirements.

Reliable accuracy even in the harshest environments
The AVS701 features a robust thin-film ceramic sensing element protected by a durable stainless-steel probe head. A special coating on the sensing element protects against moisture or corrosive substances such as hydrogen peroxide or ammonia. This makes the sensor especially suitable for highly demanding environments, including pharmaceutical and chemical industries.

In long-term tests under increased ammonia exposure, conventional sensors typically failed after an average of 440 hours, showing significant corrosion and electrical malfunction. In contrast, the AVS701 remained fully functional even after more than 1,000 test hours—without corrosion and with stable sensor data.




Significant time savings thanks to intelligent gas adaptation
The AVS701 includes a flexible process gas library that automatically applies gas-specific corrections. This function adjusts measurements to the properties of the selected process gas, minimizing measurement errors and ensuring high accuracy—even when switching between gases such as CO₂ or argon. The appropriate gas can be selected quickly via the control interface, making the sensor immediately ready for use. This results in considerable time savings and increased process safety, as precise parameterization occurs automatically and potential sources of error are reduced. The intelligent gas adaptation thus enables simple, efficient process control.

The AVS701 stands for precision and reliability in air and gas velocity measurement. With state-of-the-art thin-film ceramic technology, robust construction, and easy installation, it is the ideal solution for the most demanding industrial environments.
