ir pollution is a growing global challenge for both the
environment and public health, with ultrafine particles
(UFPs) playing a critical role. Accurate and reliable
monitoring of these particles, smaller than 100 nanometers,
is one of today’s most demanding tasks. To address this
need, AVL has developed the AVL UltraFine Particle Monitor™,
building on decades of expertise in particle measurement
from the automotive sector. This device uses state-of-the-art
technology to measure particle number concentrations down
to 10 nanometers (nm) in size.
The AVL UltraFine Particle Monitor features robust optical
components engineered for harsh operating conditions.
Automatic drift detection and reboot functions ensure a
VL’s advanced measurement portfolio offers un-
matched capabilities – from high-voltage power anal-
ysis to real-time data acquisition and ultra-accurate
current sensing. At its core is the new AVL X-ion™ PA2 power
analyzer, complemented by AVL BEAT™ software and AVL
Closed Fluxgate Current Transducers (CFC). Together, they
ensure highest accuracy, seamless integration, and reliable
performance in all types of test environments.
AVL X-ion™ PA2
This high-precision power analyzer marks a new era of power
analysis for the automotive industry and beyond. The X-ion
PA2 combines precise power analysis with high-frequency
transient waveform analysis. With up to eight power channels,
high-voltage inputs up to 1,000 Vrms, and optional direct rotor
resolver inputs, it handles anything from individual compo-
nents to complete drive trains. Modular NVH inputs enable
fully synchronized correlation of electrical signals with NVH
phenomena (noise, vibration, and harshness). Galvanically
isolated high-voltage inputs meet CAT III requirements, while
parallel signal paths enable both high-accuracy energy flow
analysis and 100 MS/s snapshot acquisition for detailed eval-
uation of switching events, overshoot, and harmonics.

ization with configurable dashboards, scripting for advanced
automation tasks, and powerful post-processing. Data can
be streamed and synchronized in real time and correlated
with NVH or mechanical parameters. Tight integration with
the X-ion PA2 enables simultaneous long-term recording
and high-resolution transient analysis. BEAT supports indus-
try-standard interfaces, offers precise PTP time stamping,
and connects seamlessly with AVL PUMA 2™ and third-party
automation systems.
AVL Closed Fluxgate Current Transducers
AVL’s CFC sensors deliver per mill accuracy across a wide
frequency and temperature range. They cover currents from
milliamps to several kiloamps and are galvanically isolated
for safe use up to 1,500 Vp. TEDS-based auto-recognition and
self-parameterization minimize setup time and reduce errors.
Direct sensor supply from the X-ion PA2 ensures a clean,
interference-free connection, while the robust design and low
drift of the transducers make them ideal for e-mobility, power
electronics, and stationary energy system testing.
continuous flow of high-quality data. Its user-friendly operation
and straightforward maintenance make handling effortless.
Seamless integration into existing ambient air monitoring sta-
tions makes it the ideal solution for regulatory agencies and
research institutions seeking to implement effective pollution
control strategies and advance impactful research.
