Trafag is your specialist for highly precise and robust pressure transmitters

Products

Sensors for pressure, temperature and gas density is what Trafag stands for.

Decades of experience and our clear focus allow us to constantly improve quality and performance of our products and processes. And you get instruments which are built to last where others fail, with a long-term accuracy and robustness you can rely on.

Pressure transmitters

Trafag pressure transmitters are used for electronically measuring and evaluating pressure. Over the decades they have proven themselves in a multitude of demanding applications in harsh environments.

Electronic pressure switches

The robust electronic pressure switches from Trafag monitor the pressure behavior of liquid and gaseous media, e.g. in plant construction and mechanical engineering, hydraulic systems, process engineering, rail vehicles, shipbuilding or in water treatment.

Electromechanical pressure switches

Trafag’s electromechanical pressure switches provide high vibration resistance and switch point precision in combination with an extremely robust and durable design.

Pressure gauges

Pressure gauges for gauge, absolute and differential pressure have been proven millions of times over.

Thermostats

For 70 years, Trafag thermostats have proven their robustness in the most adverse environmental conditions.

Temperature transmitters

Temperature gauges

Gas density monitors and gas density sensors

Trafag stands for precise, reliable and maintenance-free instruments developed for the monitoring of SF₆ and other gases in the field of high- and medium-voltage switchgear.

Level sensors and switches

Accessories for pressure transmitters, pressure switches and thermostats

Trafag offers a wide range of original accessories which are ideally matched to our products.

Industries

Railway

Trafag sensors in brake systems and pantographs ensure reliable and safe operations.

Hydraulics

Even under extreme conditions, mobile hydraulic sensors from Trafag measure reliably and accurately.

Shipbuilding

Trafag measuring instruments have proven their reliability and robustness at sea for over 50 years.

Hazardous areas

Trafag draws from decades of experience in the design and manufacturing of pressure and temperature measuring instruments for Ex zones.

Large engines

Trafag sensors are monitoring pressure and temperature of fuel in large combustion engines to operate them more efficient and environmentally friendly.
