SHIPBUILDINGTemperature and pressure monitoring solutions
Trafag — Swiss quality solutions to rely on
Trafag draws from decades of experience in the design, manufacture and application of pressure and tem-perature measuring instruments for the maritime industry. We continuously meet the rising expectations of the shipbuilding industry in respect of safety and reliability of our products. We combine the product require-ments of the classification authorities with rigorous quality management in development and manufacturing. Docking times of ships are short and spare parts need to be available immediately. Trafag is able to provide this service on the spot worldwide, through its branch offices and distributors.

Pressure transmitters
Thermostats
Pressure switches
The electronic pressure transmitters are based on Trafag‘s own sensor tech-nologies: thin-film-on-steel and thick-film-on-ceramic. In combination with inhouse developed ASIC electronics they offer excellent long-term stability and high accuracy even under harshest conditions. The wide range of ex-ecutions allows a perfect fit for a wide range of applications.
Ex- version available
Trafag‘s mechanical pressure switches offer high vibration resistance and switchpoint accuracy in combination with an extraordinary rugged design for years of maintenance-free operation in rough conditions. Different sen-sors based on bellow, membrane and piston principle cover a wide range of pressure ranges, media and load cycle profiles.
Ex- version available
Over 50 years of experience in successfully supplying thermostats to the shipbuilding industry, Trafag products have a long track record of proven reliability and accuracy. Different product lines with a variety of features and options offer a wide media temperature range and high switchpoint accuracy in a very robust design.
