With its industrial PMX measuring amplifier system, HBM enables the automotive industry to conduct much more efficient engine testing. Two of the main advantages of PMX are noise immunity, encountered in industrial settings and the precision it brings to process control.
The aim is to continuously improve the performance of today's and tomorrow's engines so that they can meet future energy efficiency standards and also enable major innovations to increase the quality of controls and manufacturing. HBM Test and Measurement designed the PMX measurement system, a precise and noise-insensitive measurement platform for test benches to improve engine efficiency.
New possibilities for filtering and scaling the torque range allow the system to be used accurately over a portion of the measurement range. The torque sensor can be scaled in the PMX by following two procedures: either using the polynomial feature, a very precise method, or with the feature board, with automatic detection of the direction of rotation.
HBM has integrated a CASMA (Crank Angle Synchron Moving Average) filter into the PMX with a slippery average calculated according to the rotation angle. For example, this next-generation filter allows you to calculate the slippery average based on the angle of the vilebrequin to determine the distribution of torque according to the cylinders.
The PMX generates feature sizes such as power, average value and peak value in real time, and even regulates torque with a PID regulator. The PMX measuring amplifier system and its open communication interfaces enable, together with HBM efficient torque meters, to carry out efficiency testing procedures in the automotive sector.
