AVL M.O.V.E PM PEMS

o Combination of 2 mass related measurements (Micro Soot Sensor and Gravimetric Filter Module)

o Constant dilution/ no proportional sampling, no real-time exhaust flow signal needed for control

o Continuous sampling (no delay/ switching times, no data loss)

o Dual voltage: 115/230V AC and 24V DC

Dual filter holder for 47mm particulate filters (measurement and back-up filter) NEW!

Dust protected filter cassette NEW!

1.5m Heated line extension (4.5m max. length) NEW!

Dual power: either 110V or 24V NEW!

Constant dilution (– no online exhaust flow signal required)

Dilution air conditioning

TE cooler, water trap/ condensate pump, active carbon and HEPA filter

Temperature conditioning (heated compartments with ventilation):

Filter compartment

MFDs, dilution cell, heated line

Filter overloading protection (bypass, soot mass monitoring)

Full set of diagnosis feature e. g. relative calibration of the MFC against the CFOs

AVL M.O.V.E GAS PEMS – Highlights

High Accuracy & Long Term Stability

“test cell grade” analyzers optimized for mobile use (HFID, NDUV, NDIR)

All analyzers are kept in temperature controlled enclosures

2-Stage cooler for minimized loss of NO2

Very low drift (~2ppm NO/NO2; ~1ppm THC over 8h)

Robust against Temperature & Vibrations

extended operating temperature range (-30°C to 45°C)

dedicated heating circuit for condensate/ ice removal

Internal and external damping measures

Reduced Operating Costs and Easy Handling

NDUV sensor for parallel measurement of NO and NO2

avoids need for ozonizer / converter

internal calibration with gas filled cuvettes

only FID fuel is needed as operating gas

scheduled start-up procedure available (timer)

hibernate mode for short warm-up time

AVL M.O.V.E PEMS System Benefits

COMPLETE

Complete and integrated In-Use Testing solution (PM,GAS, Mounting & Power supply)

FLEXIBLE Safeguard of investment due to a modular approach – additional devices like fuel consumption measurement devices, indicating equipment can be easily connected - NOx probes can be integrated via CAN bus

EASY TO USE Central data logging (one File) and central control of the devices (AVL System Control) avoids working with different Software/ PCs and therefore reduces the training effort and the time required for data evaluation (time alignment + copying the data together)

SAVES TIME Concerto PEMS reduces the time needed for data evaluation from days to minutes. It supports both – the US EPA HDIUT and European ISC legislation

LESS MISTAKES User guided semi-automated test sequences minimize the risk of invalid test data and allows also the operation by less experienced users

INDIVIDUAL

Concerto PEMS and System Control provide a high flexibility according to the individual need of the user – it includes pre-defined templates but it is also easily possible to create new screens

INTEGRATED

For R&D testing the System Control is fully integrated into INCA (6.2) application system via OHI. Other application systems can be connected via a second CAN node

AVL M.O.V.E Integrated Mobile Vehicle Evaluation

… is a mobile testing platform that provides real-life data for integrative performance, emission and driveability calibration
