EGE Elektronik Sensor with Integrated Amplifier Productseries STA 400

Description

The EGE Elektronik Sensors with Integrated Amplifier Productseries STA 400 is the authoritative choice for decentralized flow monitoring in modern manufacturing. The “STA” series is recognized for its straightforward integration; by housing the amplifier directly in the sensor body, it simplifies wiring and reduces the space required in electrical cabinets. Operating on the thermodynamic principle, the sensor utilizes a solid-state probe to detect the velocity of the medium. As the fluid flows past the heated sensor tip, heat is dissipated; the integrated electronics measure this dissipation to determine the flow state. Because the STA 400 has no moving parts, it is immune to the mechanical failures common in paddle-style or turbine-based flow switches, such as jamming, fatigue, or bearing wear.
