Measurement technology

Various additional aggregates, which can be provided if required, are available to extend test benches for special test. Pollux develops such equipment based on customer requirements. Your requirements are currently not accommodated by the services we provide? Please contact us! We will be pleased to develop tailor-made solutions for you.

 

NVH equipment

For its integration in the test bench, Pollux provides various measurement technologies in the areas of acoustics and vibration measurement.

Areas of application:

  • Recording and evaluation of acoustic phenomena developing at components
  • Vibration tests
  • Coupling with test bench automation to automatically pass and track rotational speed in resonance and imbalance areas

 

Shaft motion tests

A multiple-channel Micro-Epsion EddyNCDT measurement system can be provided to examine the motion of exhaust gas turbocharger bearings or any other rotating components.

 

Speed measurement of exhaust gas turbocharger

Various systems can be provided to measure and record the rotation speed of turbochargers. Our test benches are not only equipped with the inductive measurement technique to record the rotational speed with magnetized lock nuts but also provide the standard systems by Acam (PicoTURN) and Micro-Epsilon (TurboSPEED).

 

Vibration measurement technique

Our measurement technology comprises one or multi-axial sensors and measuring amplifiers of various leading manufacturers such as Kistler or PCB Piezotronics.

 

Blow-by measurement

Several orifice measurement devices type Natec 627 can be provided for the blow-by measurement at combustion engines and turbochargers. With interchangeable orifices it is possible to cover a measuring range from 0.25 to 350 l/min.

 

Data Acquisition

Various measurement systems can be provided for a quick measurement and storage of analog signals. Data rates can go as far as the Megahertz range. All systems can work as stand-alone systems or can be synchronized with the test bench. 

 

Soot concentration

The AVL Smoke Meter works based on the filter method and measures the soot concentration of Diesel and GDI engine exhaust gases. With its variable withdrawal quantities and thermal exhaust gas conditioning, manifold application areas arise during the engine design phase
