The EGE Elektronik Sensors with Integrated Amplifier Productseries ST 418 S-A4 is the authoritative choice for decentralized flow monitoring in machinery with small pipe diameters or manifold blocks.
The EGE Elektronik Sensors with Integrated Amplifier Productseries ST 418 S-A4 is the authoritative choice for decentralized flow monitoring in machinery with small pipe diameters or manifold blocks. While many sensors require a larger G1/2″ port, the ST 418 S-A4 utilizes a G1/4″ thread, making it ideal for precision cooling, fine lubrication, and chemical dosing lines.
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.
