EGE Elektronik Sensor with Integrated Amplifier Productseries SN 450/1-A4-GSP

Description

The EGE Elektronik Sensors with Integrated Amplifier Productseries SN 450/1-A4-GSP represents the gold standard in decentralized flow monitoring. In modern industrial automation, reducing panel space is critical; this sensor achieves that by housing all necessary evaluation electronics within the sensor body itself. Operating on the thermodynamic principle, the sensor measures the heat dissipation caused by the flowing medium. This solid-state design means there are no paddles to break or turbines to clog, ensuring consistent performance even in media containing particulate matter or high-viscosity fluids.
