EGE Elektronik Sensors with Integrated Amplifier Productseries SN 450/1-A4-WR1 is an authoritative solution for decentralized flow monitoring where only 115V AC power is available.
EGE Elektronik Sensors with Integrated Amplifier Productseries SN 450/1-A4-WR1 is an authoritative solution for decentralized flow monitoring where only 115V AC power is available. The “WR1” designation indicates its specialized internal power stage, while the “A4” refers to its high-grade stainless steel wetted parts. By performing all signal processing “at the edge,” this sensor eliminates the need for expensive cabinet-mounted amplifiers and reduces overall system complexity.
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.

Potential-Free Relay Output: Features a changeover (SPDT) contact for versatile switching of AC or DC loads.
Thermodynamic Measurement Principle: Solid-state design with no moving parts prevents mechanical failure and clogging.
Pump Dry-Run Prevention: Automatically shutting down high-value pumps in AC-powered infrastructure when flow is lost.
Lubrication Circuits: Verifying consistent oil flow to bearings and gearboxes in large-scale machinery.
Wastewater Treatment: Reliable detection in lines containing debris that would jam mechanical turbine meters.
