EGE Elektronik Sensor with Integrated Amplifier Productseries SN 450/1 GR-VE

Description

EGE Elektronik Sensors with Integrated Amplifier Productseries SN 450/1-GR-VE represents a leap in efficiency for decentralized flow control. By housing the evaluation intelligence directly within the sensor body, EGE has eliminated the need for complex wiring to external amplifiers or rack-mounted modules. The “GR” output configuration provides a potential-free changeover (SPDT) relay contact, giving operators the flexibility to switch either AC or DC loads directly, or to provide a clean signal to any PLC input type.

Features

Integrated Evaluation Amplifier: Built-in electronics process all signals internally, reducing control cabinet space and system cost.
Potential-Free Relay Output (GR): Features a changeover (SPDT) contact for versatile switching of diverse industrial loads.
Thermodynamic Measurement: Solid-state design with no moving parts ensures maintenance-free operation and high resistance to particulate matter.

Applications

Pump Dry-Run Protection: Instantly detects the loss of fluid to prevent catastrophic pump failure in 24V systems.
Cooling System Verification: Monitoring water flow in welding robots, induction furnaces, and power electronics.
Industrial Lubrication: Verifying that oil is reaching critical bearings in heavy rotating machinery and gearboxes.
