For decades, we have developed and supplied high-quality pressure transmitters, temperature sensors, gas density monitors, level sensors and accessories that are trusted across some of the most demanding industries. Our solutions are relied upon in rail transport, shipbuilding, large engines, hydraulics, hazardous areas, hydrogen applications, test and measurement environments, and more.

What makes Trafag different is the combination of Swiss engineering, robust design and long-term reliability. In critical applications where downtime is costly or safety is at stake, accuracy and durability cannot be compromised. Every product we deliver is built to withstand harsh conditions while maintaining consistent performance over many years of service.
