FEMA Controls Honeywell GmbH - a short history

Honeywell FEMA pressure monitors and limiters for safety applications make a significant contribution to the safe operation of machines and plants. With certifications according to the Pressure Equipment Directive, the Gas Appliance Directive, and the Explosion Protection Directive, the devices can be used to a wide extent to monitor flammable liquids and gases, as well as steam and hot water. SIL2 Certification as per IEC 61508 makes them suitable for use in areas in which the functional safety of plants is calculated on the basis of failure probabilities.

Additionally, Honeywell FEMA also carries pressure switches and pressure transmitters for air, gases and liquid media. Especially our electronic pressure and differential pressure switches as well as transmitters can help solve a variety of measurement and switching tasks in the area of machine and plant construction. A wide portfolio of components for air conditioning technology round out the company’s portfolio.

Company History

The history of our company begins in 1938 in Stuttgart. Two engineers, Vollrad Weber and Walter Freund, founded "Weber und Freund OHG." The product line included mechanical pressure switches, thermostats, and magnetic valves for industrial applications and heat technology.
After the company was taken over by ZENTRA Albert Bürkle KG in 1970, the products were re-engineered and new distribution structures were established.
There was a big breakthrough in 1974: With newly designed pressure and temperature switches, FEMA was a pioneer in the area of the safety monitoring of pressure vessels. Already, the technical testing of the products verified that they were suitable for use in safety-relevant applications (e.g., in ex-protection steam plants).

Integration of FEMA in the Honeywell Organization

In 1984, CENTRA-Bürkle GmbH & Co was taken over by Honeywell, and FEMA, too, was thus integrated into Honeywell's organization. FEMA Regelgeräte Honeywell AG was relocated to a new production facility in Schönaich in 1989. Since 1996, it has been doing business under the name "Honeywell GmbH FEMA Regelgeräte" – the "FEMA" trademark was thus retained. In order to ensure the continued success of FEMA products in a changing marketplace, efforts focused on product development and technical improvement. As a result, the first series of electronic pressure and temperature transmitters came off the assembly line in 1991 and 1992.

Safety and Quality

FEMA has a commitment to providing high-quality products and competent customer service. FEMA control units are manufactured according to the most-stringent quality standards at our main headquarters in Schönaich and have a reputation for reliability. FEMA pressure switches, transmitters, and thermostats fulfill the criteria of SIL 2 (Safety Integrity Level 2) according to IEC 61508-2. They thus stand for "functional safety" and guarantee safe and reliable production in conjunction with additional safety-relevant components (e.g., actuators and controllers). IEC 61508-2 is the basis for the manufacture of safety-relevant components for process automation. In addition to this comprehensive product portfolio, FEMA's wide range of additional functions and matching chemical seals allows the adaptation of pressure and temperature measurement systems to various different application scenarios.
