Trafag is one of the world’s leading suppliers of high-quality sensors and monitoring devices for pressure, temperature and SF6 gas density. In addition to a wide range of standardised, configurable products, Trafag also develops tailored solutions for OEM customers. Trafag’s pressure transmitters, pressure switches, temperature transmitters and thermostats are used in shipbuilding, hydraulics, the railway industry, large engines, zones at risk of explosions (EX), water treatment systems, test benches, and more. The SF6 gas density sensors and SF6 gas density monitors are used for high- and medium voltage switchgears.
Trafag was founded in 1942 and is based in Switzerland. The company has an extensive distribution and service network in over 40 countries worldwide. This enables the company to provide individualised, competent customer support and guarantees fast service. High-performance development and production departments not only guarantee the fast and reliable delivery of our high-quality and high-precision products, but also ensure that customisations can be implemented in no time at all.
Trafag was established in 1942 as a family business, initially manufacturing transformers. Over the years, Trafag developed, produced and sold mechanical regulators for pressure and temperature with thermostats and pressure switches. At the same time, the sales network was steadily expanded with distributors and subsidiaries. The step towards developing and producing pressure transmitters was made possible by the in-house development and production of sensor membranes. For the monitoring of gas density in high- and medium-voltage systems, mechanically functioning gas density monitors were added first, followed by gas density sensors. With the development of its own ASIC microchip for sensors and investments in the magnetic field technology, Trafag can rightly call itself a high-tech sensor company and is successfully positioning itself as such on the international market – and has done so for more than three-quarters of a century.
