Our quality is no coincidence. We are always working to achieve the best results for our customers. We do this using precision, a love of detail, and state-of-the-art quality management processes.
As early as 1995, we introduced our quality management system which was certified in line with ISO 9001. Since then, we have developed it further to create an integrated management system that combines the factors of quality, environmental protection, occupational safety and plant reliability. All processes in the various departments are documented in detail; internal and external audits are continuously checked.
In addition, quality assurance monitors adherence to statutory regulations (conformity with standards) and technical specifications: 100 percent. After all, every single one of our items passes through the quality assurance inspection labs as part of the final checks. These checks examine the function, insulation and voltage resistance, and subject every sensor to an optical and some sensors to a mechanical material inspection. Automated processes and high-quality testing and measuring equipment ensure error-free measurements and transparent documentation. This comprehensive quality testing guarantees long-lasting products under global operating conditions,
All our procedures and production regulations are continuously checked and further developed. It is a task for everyone, giving all our staff the opportunity to contribute their ideas and suggestions for improvement regularly. Requests and requirements from our customers also provide us with valuable feedback time and again, so we can optimise our processes even further.
*Philip B. Crosby put together this idea of quality management more than 50 years ago. And we at EPHYMESS use it to this day. After all, we work hard to achieve the best possible quality every day.
Very different test criteria are the focus, depending on the application. What they all share is an uninterrupted test procedure – no ifs or buts. The EPHYMESS quality test can only be passed if all required properties are proven in full. The quality-related measuring and testing equipment is calibrated regularly and subject to constant monitoring.
Using a temperature block calibrator allows the properties of the test object to be determined in the gaseous medium (air) under prescribed temperatures (+35°C ... +550°C). Limit deviations of the platinum resistance thermometers are measured using cold/heat thermostats in liquid media under prescribed temperatures (-50°C ... +180°C).
The quality of the insulation is in the spotlight in the partial discharge test, which looks at the dielectric field strength typical of the material, the partial discharge inception voltage, the partial discharge extinction voltage, and the level of partial discharge, among other aspects. A partial discharge test bench is available to determine the performance features for air gaps, creepage distances and fixed equipment insulation in high-voltage tests over 5 kV.
Test range: up to 20,000 V AC
Frequency range: 0.3 Mhz to 2.5 Mhz
Measuring range: 2.5 pC to 25.000 pC
A key parameter for the EPHYMESS components is the tensile strength of the connection between the sensor and the supply line. A universal tension testing machine allows measurements to be conducted in the 1N to 1000N range. The results achieved in measuring data recording are documented digitally using a characteristic curve and results table.
The reaction time is the time a temperature sensor needs after a temperature leap to display a certain part of the temperature leap as a change in resistance. The test can be conducted in flowing air or water. EPHYMESS determines both the time t=0.5 and t=0.9 for 50% and 90% of the temperature leap. The reaction time of a sensor is largely determined by its construction. A clever choice of material for each application allows this value to be optimised.
Founded in 1980 as AMA Arbeitsgemeinschaft Messwertaufnehmer e.V., AMA Fachverband für Sensorik und Messtechnik e.V. now has around 480 members, more than 70 of whom are R&D institutes. AMA sees itself as representing the interests of everyone working with technical measurement systems (measuring or switching) for a wide range of different applications throughout the supply chain. This covers the entire value chain for sensor technology/measuring systems – from fundamental research, to manufacturers and service providers; from microtechnologies and sensor elements to complex measuring, testing and control systems and actuator engineering. EPHYMESS has been a member since 1989 and has provided the cash auditor for a decade.
BZEE, the Education Centre for Renewable Energies, was set up in Husum in 2000 together with the Bundesverband WindEnergie, the Chambers of Industry and Trade, and numerous wind energy companies. Since then, it has been training the staff needed to service, maintain and repair wind energy plants worldwide. BZEE e.V. has 90 companies from the wind energy sector as members, who constantly work with the BZEE staff to create training content and courses adapted to the latest demands of the sector. EPHYMESS has been a member since 2009.
The Verband der Bahnindustrie in Deutschland (VDB) e.V. is an umbrella organisation that brings together rail technology manufacturers in Germany. Its over 215 member companies include the major systems houses and all key medium-sized companies in the sector. The VDB represents the interests of its members to policymakers, media, ministries, authorities and a wide range of rail transport companies and institutions, and has done for almost 150 years. The Association is divided into 19 expert groups and working groups, to which the member companies appoint their experts. EPHYMESS has been a member since 1998, with its Managing Director, Andreas Becker, Vice President of the VDB for the last ten years.
The specialist association represents the economic, technical and industry-policy interests of the supplier industry for transformers, electric motors and generators in Germany and Europe. Its aim is to permanently improve the innovative strength and international competitiveness of its members and the close collaboration with its partners in the supply chain, in national and international networks and committees, and with political decision-makers. The ZVEI promotes the development and use of new technologies by making proposals for research, technology, environmental protection, education and science policy. It supports market-linked, international standardisation work. EPHYMESS has been a member since 2005.
