Torque monitoring

Turbocharger applications

At a time when oil prices are constantly rising and the discussion about CO2 emissions is becoming more and more intense, the fuel consumption of a vehicle is of eminent importance for sales success. The turbocharger is a contribution to improve the efficiency of vehicles. For this reason, there are currently a number of new turbocharger developments. During the qualification process, the rotating components in particular must be assessed for stress and optimized with regard to the load limits in different operating situations. As is well known, these turbochargers rotate up to 200,000 rpm in the vehicle sector.

In addition to measurements of blade vibrations and bearing temperatures, we offer highly precise applications for measuring torques on the turbocharger shaft. At the highest speeds, the measurement data is recorded exactly and transferred to the evaluation unit or computer as usual without contact.

The miniaturized design and the extremely low installation costs are the result of years of development work together with the turbocharger industry.

The electronics and transmission antenna are located in a cartridge-shaped housing that weighs only 5 grams and is 35 mm long. It is screwed onto the shaft thread at the turbocharger inlet. The inductive coupling takes place at the inlet port and can process up to four sensor signals in parallel. The digital resolution of the measurement signals is 16 bits, the temperature stability of the rotor electronics is 160° Celsius.

Bearing temperature detection

Bearing temperature detection

The turbine of the turbocharger converts flow energy into high rotary motions; in the case of the compressor, the rotary motions are converted back into flow work. Modern turbochargers can achieve speeds of up to 200,000 rotations per minute. Such speeds can only be achieved with optimum shaft bearings. The sliding friction surface, bearing technology and other factors determine the temperature of the bearings, which can be easily measured with the aid of MANNER sensor telemetry.

Whether plain or ball bearings and regardless of the materials used, MANNER sensor telemetry offers you highly precise applications for recording bearing temperatures. The miniaturized design and extremely low installation costs are the result of many years of development work together with the turbocharger industry.

Sensor telemetry applications

Sensor telemetry applications

Die Sensortelemetrieapplikationen von MANNER sind vielen Kunden besonders an den sogenannten Schaufeln eines Strömungs- und Verdichtungssystemes wie dem Turbolader wichtig. Die hochfrequenten Schwingungen dieser Schaufeln werden bereits in zahlreichen Fällen mit Hilfe unserer Messsysteme erfasst und präzise aufgezeichnet. So können wichtige Informationen für die Gestaltung von Verdichterbeschaufelung bezüglich Festigkeit und Aerodynamik gewonnen werden.

MANNER’s sensor telemetry applications are particularly important to many customers on the so-called blades of a flow and compression system such as a turbocharger. The high-frequency vibrations of these blades are already recorded and precisely recorded in numerous cases with the aid of our measuring systems. In this way, important information can be obtained for the design of compressor blades in terms of strength and aerodynamics

The blade and shovel vibrations are precisely recorded at maximum speeds and transmitted to the evaluation unit or computer as usual without contact. The miniaturized design and the extremely low installation costs are the result of many years of development work together with the turbocharger industry.
