EGE Elektronik Sensors with Integrated Amplifier Productseries SC 440/3-A4-GSP

Description

The EGE Elektronik Sensors with Integrated Amplifier Productseries SC 440/3-A4-GSP represents the gold standard in modern flow sensing technology. Designed to streamline industrial automation, this sensor incorporates all necessary signal processing within its own body. It operates on the thermal principle: the sensor tip is heated, and the flowing medium dissipates that heat. This allows for highly accurate detection of flow speeds without the use of paddles or turbines that are prone to clogging, breaking, or wearing out over time.

Features

Integrated Evaluation Amplifier: Built-in electronics enable direct PLC connection, saving space and reducing wiring complexity.
Thermodynamic Measurement: No moving parts in the flow stream, preventing mechanical failure and ensuring long-term stability.
Extended Probe Length: The SC 440/3 variant offers optimized immersion depth for larger pipe diameters or specific installation requirements.

Applications

Pump Dry-Run Prevention: Detecting the absence of liquid to automatically shut down pumps before cavitation or heat damage occurs.
Industrial Lubrication Systems: Verifying oil flow to critical bearings and gearboxes in large machinery.
Chemical and Process Industry: Monitoring the movement of aggressive fluids in pharmaceutical or chemical production lines.
Large Diameter Piping: The extended probe length of the SC 440/3 is ideal for ensuring the sensor tip reaches the center of the flow profile in wider pipes.
