Automobilový vývoj

Vehicles must already prove their suitability for later use in the first stages of development. At the same time, not only functionalities but also stabilities, expansions, vibrations and many other things are tested. The extensive use of measurement technology in the vehicle development phase often provides new perceptions and helps to design safer and more comfortable modern vehicles.

Brake disc concentricity

Brake discs are subject to the highest loads in use and are responsible for the safety of vehicles. For this reason alone, brake discs are thoroughly inspected on test benches. Brake discs are checked ...

Brake disc temperature measurement for Formula Student

In the optimisation of braking systems for the High Octane Motorsports e.V. racing car at the University Erlangen-Nürnberg, the temperature rise of the brake disc needs to be measured during on-road testing.

Injector needle lifting

Combustion engines are a combination of many different technologies. Therefore, the precision of each individual one is responsible for the performance of the engine. The actual injected amount of fuel for Common ...

Pinching protection

Automatically closing doors, flaps or covers always have the danger of pinching a finger or the hand. There are systems for this which stop the movement in such a case. However, as the finger is already pinched, any ...

Pistons

Combustion engines must withstand maximum loads during a long service life. In order to deal with this requirement, eddy current sensors from the eddyNCDT series are installed in the engine for many different measurements. ...

Piston – Top Dead Centre

The Top Dead Centre of the cylinder movement is measured for adjustment of the precise ignition point in engine development. In doing so, a miniature eddy current sensor is integrated in the cylinder head cover. From this position, ...

Piston secondary movement

Among other things, the lateral movement of the piston in the cylinder is crucial for the service life of engines. Miniature eddy current sensors for this are integrated in the piston which measure onto the cylinder wall. If the distance ...

Oil film thickness

The oil film thickness for combustion engines describes the gap and thus the quantity of oil between piston and cylinder wall. Thus it is sometimes a determining factor for smooth operation and durability. As the oil film can only be integrated ...

Profile

Profile measurement generally describes the measurement of the object contour, flat or as a track. Basically, it is possible that either the sensor traverses across the object or the object moves through the measuring range of the sensor. It is ...

Groove

A groove can occur in many different objects as a sustained depression. Whether a groove is desired or not is the question. If a single track measurement of a groove is sufficient, laser point sensors, confocal, capacitive or eddy current sensors ...

In-line inspection of the rubber on windshield wiper blades

A faultless surface is indispensable for the functionality of wiper blades. Therefore, wiper blades are inspected by the measuring system after the extrusion in the endless state. In doing so, two scan CONTROL 2800 sensors are used. The inspection ...

Lubrication gap

Sliding bearings are used for crankshaft bearings in the engine. A specific minimum distance is required so that the bearing operates as wear-free as possible. Miniature eddy current sensors are integrated in the bearing for this. They measure the ...

Turbochargers

Apart from the angle of the guide vanes, the speed of the vanes on the turbine wheel is important for the performance of the turbocharger. The rotation of the vanes is measured on the face side for this. Due to increasing material stresses and speeds ...

Valve lift sensor

Controlling the valves of combustion engines using electromagnetic actuators is a current objective of many engine developers. This technology makes possible potential fuel consumption savings of 8% - 9%. Sensors for checking the movement are necessary ...

Low cost sensors for cylinder applications

Monitoring the movement of gas pressure or hydraulic cylinders is solved very elegantly using an eddy current sensor. This sensor is integrated in the cylinder. An aluminium ring is used as the target. The sensors are designed so that they easily withstand ...

Cylinder breathing of the cylinder head gasket

Specially shaped eddy current sensors are integrated directly in the crankcase where they measure, for example, the expansion of the cylinder head gasket during the stroke. Pressures of up to 50 bar are produced for every ignition of a cylinder, which slightly ...
