AMEPA

What AMEPA does

AMEPA Angewandte Messtechnik und Prozessautomatisierung GmbH is a German industrial measurement technology company headquartered in Würselen, founded in 1984 as a spin-off from RWTH Aachen University. The company designs, manufactures, and services specialized measurement systems for quality assurance in steel, aluminum, and automotive production. Its product portfolio is organized into two functional groups: liquid-steel slag detection systems (ESD electromagnetic slag detection with the industry-unique dual-channel ESD 400; TSD thermographic slag detection via infrared camera; and RSD electromagnetic residual steel detection for tundishes) and surface-quality measurement systems (SRM online roughness, WMS online waviness, OFM online oil film, and OFIS portable oil film measurement). The underlying technology combines electromagnetic eddy-current sensing, infrared thermography, line-projection laser triangulation (under European patent EP2517799 licensed from CRM Group, Liège), and mid-infrared spectroscopy.

AMEPA generates revenue primarily through direct enterprise sales of these systems, project-based customization, installation, commissioning, and ongoing service contracts. The company operates a hybrid go-to-market model: direct sales from its Würselen headquarters supported by wholly-owned subsidiaries AMEPA America Inc. (Solon, OH, est. 1994) and AMEPA Trading (Shanghai) Co., Ltd. (est. 2020), combined with a global network of regional sales and service partners across Europe, Asia, Oceania, and the Americas. Customers include major steel producers, aluminum manufacturers, and automotive OEMs and tier suppliers (notably thyssenkrupp Steel Europe and Porsche's Smart Press Shop via Schuler Pressen). With more than 3,600 ladles equipped and 500+ plant installations across over 50 countries, AMEPA claims world market leadership in electromagnetic slag detection. The company is privately held with no external institutional investors, led since 2019 by two Managing Directors, Martin Fieweger (sales and service) and Armin Kempkes (development and production), and employs 60+ staff.

Core offering

AMEPA develops, manufactures, and sells industrial measurement systems for quality assurance in steel, aluminum, and automotive manufacturing. The product portfolio includes electromagnetic and thermographic slag detection systems (ESD, RSD, TSD) for liquid steel processing, online surface measurement systems for roughness, waviness, and oil film (SRM, WMS, OFM), and a portable handheld oil film measurement device (OFIS). Systems are integrated into continuous casting lines, rolling mills, and press shops with installation, commissioning, and ongoing service support.

Product overview

AMEPA offers a portfolio of seven specialized measurement systems for the steel, aluminum, and automotive industries. The product line includes three slag detection systems (ESD electromagnetic, TSD thermographic, and RSD residual steel detection) that ensure slag-free transfer of molten steel in the liquid stage. Complementing these are four surface measurement systems (SRM roughness, WMS waviness, OFM online oil film, and OFIS portable oil film) that monitor surface quality parameters throughout the production process from rolling mills to press shops. All systems are designed for industrial environments with features like non-contact measurement, validation units, and database storage for quality documentation.

Products and services

• ESD Electromagnetic Slag Detection (ESD 300/400) Electromagnetic slag detection system installed at the ladle bottom that detects slag flow through and automatically closes the slide-gate valve. Reduces slag carryover by up to 90%. ESD 400 features unique dual-channel technology for detecting individual slag particles before continuous slag flow begins. Targets steel producers operating continuous casting lines.
• RSD Residual Steel Detection (RSD 300) Electromagnetic measuring system for tundishes on continuous casting lines that monitors low steel levels by detecting the steel/slag interface using transmitting and receiving coils with eddy current measurement. Enables safe tundish drainage without slag carryover while maximizing yield and minimizing mixing zones during grade changes. Targets steel producers.
• TSD Thermographic Slag Detection (TSD 2.0) Optical slag detection system using infrared camera technology to detect slag flow when transferring molten steel from oxygen steel converter or electric furnace to ladle. Exploits different thermal radiation characteristics of steel and slag in the higher infrared range. No sensors installed in vessel, resulting in low maintenance costs. Targets steel producers.
• SRM Online Roughness Measurement (SRM 100) Non-contact online roughness measurement system using line projection laser triangulation method patented by CRM Liège. Provides Ra measurements from 0.3 to 3 µm with measurement frequency up to 100 Hz. Visualizes and documents roughness over the entire coil length for optimal process control. Targets steel and aluminum rolling mills.
• WMS Online Waviness Measurement (WMS 100) Online waviness measurement system based on line projection laser triangulation using microscopic online triangulation with microlines and image stitching. Provides Wsa measurements from 0.1 to 1 µm at strip speeds up to 180 m/min. Patented by CRM Liège (European patent EP2517799). Targets steel and aluminum surface quality control.
• OFM Online Oil Film Measurement (OFM 300) Non-contact online oil film measurement system using infrared spectroscopy in the mid-infrared range (MIR). Uses spectrally broadband halogen light sources where oil causes specific wavelength absorption dependent on oil layer thickness. Provides immediate online warning of deviations in oiling process. Includes validation unit for regular sensor checking and automatic fault detection. Targets steel, aluminum, and automotive production lines.
• OFIS Portable Oil Film Measurement (OFIS 3.0) Handheld portable oil film measurement device using infrared spectroscopy for mobile measurement of oil films and dry lubes on metallic surfaces up to 5 g/m². Features ±0.05 g/m² accuracy (up to 1 g/m²), wireless data transfer, one-second measurement time, storage for up to 224 measurements, and IP54 industrial rating. Targets steel, aluminum, and automotive quality assurance.
