Pressure transmitters
Electronic pressure transmitters are the heart of Trafag's offer. Thanks to fully welded sensor systems without O-rings (sealing rings), these devices provide maximum long-term stability and resistance to high temperatures of working fluids. They are ideal for pressures up to 3000 bar, offering exceptional precision even in the most difficult operating conditions.

Electronic pressure switches
These devices are the first choice for precise pressure monitoring of liquid and gaseous media. They are characterized by high precision and the possibility of simple configuration via smartphones thanks to the integrated NFC technology and the application "Trafag Sensor Master". They often come with overview screens to track values ​​in real time.

Electromechanical pressure switches
Trafag's legendary robustness is best reflected in mechanical pressure switches. With sensor elements based on bellows, membrane or piston, these devices guarantee a precise point of fit and decades of maintenance-free operation, even under conditions of constant vibration and shock.

Manometers
Trafag manometers for absolute, differential or relative pressure have proven their reliability millions of times. They are available in a variety of materials, from copper alloys to stainless steel, to meet the specific requirements of each industrial application.

Gas density monitors and sensors
Trafag is a world leader in the monitoring of insulating gases, such as SF6 and more environmentally friendly alternatives, in high-voltage installations. Their solutions include mechanical monitors with a reference chamber and electronic sensors with patented quartz tuning fork technology, which measure gas density directly and without the influence of pressure changes caused by temperature.

Level sensors and switches
For precise level measurement in tanks, Trafag offers continuous sensors with a float (potentiometric type), optical sensors without moving parts, as well as conductive probes. They are available in materials such as stainless steel, PVC or brass, adapting to the aggressiveness and viscosity of different industrial fluids.

Shipbuilding and large engines

With a tradition of more than half a century, Trafag is a reliable partner in the maritime industry. These sensors have certificates from ten leading world classification societies.
Application includes monitoring of drive systems, pumps, ballast water treatment, control systems and tanks.
In the development of large engines, these devices precisely monitor the fuel injection pressure (over 2000 bar), which increases efficiency and significantly reduces the emission of harmful gases.

Hydraulics (mobile and stationary)

Hydraulic applications require extreme durability. Trafag pressure transmitters have proven superior long-term stability in the most difficult operating conditions – from desert heat to arctic cold.

• Mobile hydraulics: Application on construction machines (excavators, cranes), agricultural and forestry machinery, as well as utility vehicles.

• Stationary hydraulics: Key role in valve control and tank monitoring, thus preventing costly downtime in production processes.

Railway technology

In a sector where safety and reliability are absolute priorities, Trafag equipment meets the strictest standards (such as EN 50155).
Sensors are an integral part of brake systems (pneumatic and hydraulic), pantheographs, as well as suspension and air conditioning systems in high-speed trains, trams and metros.

Energy and monitoring

Trafag is a global leader in the monitoring of insulating gases (such as SF6) in high-voltage and medium-voltage installations.
World-leading manufacturers such as Hitachi Energy and Siemens Energy rely on this technology to ensure the stable operation of distribution networks, substations and transmission lines.

Hydrogen industry

As a pioneer in clean energy solutions, Trafag offers sensors made of special steel alloys (such as austenitic steel reinforced with nitrogen).
These materials are resistant to hydrogen embrittlement and permeation, which makes them essential for the operation of H2 pumping stations, high-pressure tanks (up to 1000 bar) and fuel cells in modern mobility.

Process industry and water treatment

A wide range of Trafag components are used in the chemical, petrochemical and pharmaceutical industries, as well as in food and beverage production.
The equipment is adapted to specific requirements, including hygienic connections and high resistance to aggressive chemical media in wastewater treatment plants.
