Captor
Captor, the flagship brand of Weber Sensors GmbH, has specialized in industrial sensor technology for over six decades, delivering high-precision, extreme-environment-ready solutions to global manufacturing sectors.
Brand Positioning & Core Competencies
Captor focuses on R&D and manufacturing of industrial sensors across three key domains: flow monitoring, hot metal detection, and inductive proximity switching. Its technological edge lies in extreme environmental adaptability and mission-critical reliability.
Flow Sensors: Utilize thermal mass principles to operate stably from -20°C to +135°C, achieving measurement accuracy <2%.
Hot Metal Detectors: Employ infrared sensing with a 16ms response time, tailored for high-temperature scenarios like furnaces and continuous casting lines.
