EGE Elektronik Sensors with Integrated Amplifier Productseries SNS 450-A4-WR1 represents an authoritative solution for decentralized flow monitoring where only AC power is available.
EGE Elektronik Sensors with Integrated Amplifier Productseries SNS 450-A4-WR1 represents an authoritative solution for decentralized flow monitoring where only AC power is available. The “WR1” designation signifies its optimization for 115V AC operation, featuring a built-in relay that provides a potential-free changeover contact. This enables the sensor to switch loads directly or interface with AC-based control logic without the complexity of additional power conversion hardware.

Relay Output (Potential-Free): Provides a flexible changeover contact for direct switching of AC or DC loads.
Thermodynamic Principle: No moving parts in the flow stream ensures immunity to mechanical wear and clogging.
Pump Dry-Run Protection: Ideal for protecting large industrial pumps where AC relay control is preferred for emergency shutdowns.
Industrial Ventilation: Detecting airflow in extraction systems and cleanrooms to ensure environmental safety.
Heavy Manufacturing: Verifying consistent coolant flow for large transformers and induction heating units.
