EGE Elektronik Sensor with Integrated Amplifier Productseries SN 450/1 GA

Description

The EGE Elektronik Sensors with Integrated Amplifier Productseries SN 450/1-GA is an authoritative choice for industrial automation architectures based on NPN logic. By housing the signal evaluation intelligence directly within the sensor body, EGE eliminates the need for external transducer modules or additional space in the control cabinet. The “GA” designation specifies the NPN switching output, delivering a reliable sinking signal to your PLC or localized control unit whenever the flow exceeds or falls below the adjusted set-point.

Features

Integrated Evaluation Amplifier: All electronics are built into the sensor head, reducing wiring complexity and saving cabinet space.
NPN Switching Output (GA): Designed for direct connection to NPN-compatible PLC inputs and industrial controllers.
Thermodynamic Measurement: Solid-state design with no moving parts prevents mechanical failure and clogging.

Applications

NPN-Logic Automation: Seamless integration into Japanese-standard PLCs or specific industrial control systems.
Pump Dry-Run Prevention: Detecting the loss of fluid to protect high-value pumps from heat damage or cavitation.
Cooling System Verification: Monitoring water flow in welding robots, induction furnaces, and power electronics.
