4 04. TEST AND MEASUREMENT Test facilities Quality Assurance Routine testing Our quality assurance monitors compliance with legal requirements (standards) and technical specifications. At EPHY-MESS each article undergoes tests to control e.g. dimension, tension, pressure, tightness, functionality, insulation and dielectric strength at the final inspection section of the quality department. In addition in the course of its compliance with standards, each sensor has to fulfill an optical inspection as well as in some cases additionally mechanical testing. The system-optimized, automated and computer-based processes as well as high quality test and measurement equipment ensure accurate measurements and traceable documentation. Continuous improvement EPHY-MESS continuously monitors the workflow and production requirements. Our employees present their ideas on how to optimize processes to the product manager. The implementation improves and accelerates the production of our products while maintaining high quality standards. Relentless testing Different test criteria are being applied depending on the application. They all include a relentless test procedure. Only products that possess all required properties without any fault can pass the EPHY-MESS quality test. The quality-related measurement and test equipment is calibrated regularly and is subject to continuous, documented monitoring. Temperature tests Thermal response times High voltage acceptance tests Insulation resistance tests Partial discharge tests Microscopic examinations Pressure and tensile tests Climate tests Leak tests Vibration characteristics 6 Product overview EPHY-MESS GmbH Rev EPHY-MESS GmbH Product overview 7

In short: designed and made in Germany 8 Product overview EPHY-MESS GmbH Rev EPHY-MESS GmbH Product overview 9

6 ON TRACK EPHY-MESS keeps fit rolling stock Particularly the sensors in high-speed trains must work with absolute reliability under diverse operating conditions. EPHY-MESS temperature sensors, speed sensors and oil level gauges meet these requirements and have proven themselves in world-renowned international train projects. Forces created by shocks require that the sensor elements possess a special internal structure to ensure the continuous capture of reliable measuring values. Over the years EPHY-MESS has gained valuable experience and a thorough knowledge of this technologically demanding field. The modular concept - developed especially for rolling stock - enables quick and cost-effective integration of various sensors in a sensor system. Beside temperature sensors, speed sensors can also be integrated in the EPHY-MESS sensor concept. Single modules can be mounted to one completely assembled multi-arm harness. In addition to high-speed trains, underground and suburban trains as well as buses and hybrid vehicles will also be equipped with EPHY-MESS sensors. IN THE WIND Your specialist for wind power plant temperature sensors Large wind power plants and difficult to reach offshore facilities require the highest reliability and safety for all components under increasingly critical operating conditions. Reliable continuous temperature control plays an essential role. Standard mounted coil head sensors as well as bearing and slot resistance thermometers are used to monitor temperature in generators or gearboxes and drives. We are constantly collecting and expanding our comprehensive temperature monitoring knowledge for various wind plant concepts. Due to the increased performance, the requirements for control and analysis have changed, so that many different temperature sensor types are used for monitoring tasks in wind power plants today. Against this background own product ideas are developed and discussed with potential customers. EPHY-MESS is a problem solver and development partner for its customers. Business sectors 06. BUSINESS SECTORS FOR THE INDUSTRY Large range of applications in industrial drive technology The focus of many industrial applications is the engine. EPHY-MESS sensors monitor the winding temperature of electric motors, generators, gears or transformers and are used for preventive maintenance of induction coils. They are also used in power plants to control cooling water temperature or other critical components such as coils, pipelines as well as thyristors or chokes. 10 Product overview EPHY-MESS GmbH Copyright ESO Rev Copyright Andritz AG Copyright Hitachi HCME EPHY-MESS GmbH Product overview 11
