EGE Elektronik Sensors with Integrated Amplifier Productseries SNT 450-A4-GSP is the authoritative choice for facilities requiring consolidated monitoring of both kinetic and thermal fluid properties.
EGE Elektronik Sensors with Integrated Amplifier Productseries SNT 450-A4-GSP is the authoritative choice for facilities requiring consolidated monitoring of both kinetic and thermal fluid properties. In modern high-performance systems, such as induction cooling or hydraulic circuits, monitoring flow presence alone is often insufficient—thermal stability is equally critical. The SNT 450-A4-GSP addresses both needs through a single G1/2″ process connection.
EGE-Elektronik Spezial-Sensoren GmbH has been developing and manufacturing special purpose sensors for automation applications since 1976. The company serves leading international producers from a wide range of industries. Its product portfolio includes flow controllers, infrared, opto and ultrasonic sensors, capacitive proximity switches, light barriers and inductive proximity switches. EGE also provides sensors for highly sensitive applications, e. g. hazardous areas. The development department`s highly qualified staff cooperates closely with all customers, ensuring continuous product updates and enhancement.
EGE has been a pioneer in the field of flow controller and an innovator and decisive participant in the development of today's globally utilized thermal flow controllers. The in-house EMC and test laboratories ensure that all inspections and tests required for permits and conformity certificates are carried out quickly and reliably. Product quality is guaranteed with a continuously monitored quality management system in accordance with EN ISO 9001:2000.

Simultaneous Flow & Temperature Monitoring: Consolidation of two sensors into one housing reduces installation labor and potential leak points.
Dual PNP Switching Outputs: Independent signals for flow and temperature limits, compatible with standard PLC sourcing logic.
Integrated Evaluation Amplifier: Built-in electronics process all signals internally, saving valuable space in control cabinets.
Induction Heating & Welding: Ensuring cooling water is flowing and hasn’t reached thermal limits that could damage power electronics.
Hydraulic Systems: Monitoring oil flow and preventing fluid degradation due to overheating in large hydraulic power units (HPUs).
Pump & Valve Monitoring: Protecting high-value pumps from dry-running (flow) and motor-induced heat build-up (temperature).
Heat Exchangers: Simultaneously verifying the flow rate and thermal efficiency of the cooling medium.
