Tailor-made sensors. Worldwide.

The History - Continuity and Regeneration


Hermann Seibel, a trained electrician and a banker, and his wife, a trained commercial clerk, establish EPHY-MESS GmbH. Supported by two employees, they first trade industrial measuring instruments , which they also repair.


After a move the company grows to five employees and commences the production of pressure gauges.


In this decade, EPHY-MESS fundamentally expands the product range: The company begins the production of temperature sensors, such as slot resistance thermometers and thermistors, with which the temperature evolution can be monitored in electric motors. In addition measuring resistors and thermistor version are offered. The expansion of the company leads to the relocation to Wiesbaden-Nordenstadt.


Against the backdrop of technological development, the management decideds upon a strategic realignment: the production of pressure gauges is terminated. Instead, the company concentrates on the manufacture of contact temperature sensors. The current management directors, Claudia and Andreas Becker, daughter and son-in-law, join the business.


Display and control devices for temperature sensors broaden the portfolio. Moreover EPHY-MESS begins the development of special temperature sensor (miniature technology) and sensor-integrated systems for railway traffic and equips the German Inter-City Express trains. The number of employees gradually rises to 14.


EPHY-MESS receives the certification according to DIN EN ISO 9001 for the first time. Again the company expands, into larger rented premises in Hofheim-Wallau.


The take-off of globalization in the nineties also opens up new markets for EPHY-MESS. The turn of the millennium accelerates the internationalization of business activities. South Korea and Japan are coming into view, shortly followed by China, India, Australia, USA, Brazil and several CIS countries. The company starts production of flexible band heaters for electrical machines.


Celebration of the 50th Anniversary and planning of a new, company-owned, production and administration building.


Move-in into the new headquarters in Wiesbaden Delkenheim. More than 100 employees are now working in the family business. At that time, the export share is just over 25 per cent. Beginning of the planning for a second production facility.


Completion and occupancy of the expanded production building. Meanwhile,  almost 170 employees are developing, producing and marketing high-temperature sensors for a wide variety of industries and instrumentation applications. The export to 37 countries around the world corresponds with an export share of about 40 per cent.
