Product lines for pressure and temperature control Trafag offers a wide range of products for pressure and temperature monitoring geared towards the special requirements of the marine and offshore industry.

Pressure transmitters The electronic pressure transmitters are based on Trafag‘s own sensor technologies: 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 executions allows a perfect fit for a wide range of applications.

Pressure switches 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 sensors based on bellow, membrane and piston principle cover a wide range of pressure ranges, media and load cycle profiles.
