EGE Elektronik Sensor with Integrated Amplifier Productseries SNT 450-A4-GR

Description

EGE Elektronik Sensors with Integrated Amplifier Productseries SNT 450-A4-GR is the authoritative choice for facilities requiring consolidated monitoring of fluid dynamics and thermal states on a 24V DC power architecture. In modern industrial processes, the health of a system often depends on two factors: the presence of flow and the stability of temperature. The SNT 450-A4-GR addresses both simultaneously through one G1/2″ process connection, reducing the number of potential leak points and simplifying wiring.

Features

Dual Independent Relay Outputs: Potential-free changeover (SPDT) contacts allow for universal switching of AC or DC loads.
Thermodynamic Flow Sensing: Solid-state technology ensures resistance to mechanical failure and debris.

Applications

Hydraulic Power Units (HPUs): Simultaneously monitoring oil flow and preventing fluid overheating in large-scale hydraulic systems.
Cooling Water Interlocks: Ensuring proper coolant flow and temperature in induction furnaces and welding systems.
Pump & Valve Stations: Preventing dry-running and detecting motor-induced heat build-up in the fluid.
