/ 185 PORTABLE MEASURING SYSTEM FOR GASEOUS EMISSIONS AVL M.O.V.E GAS PEMS / GAS PEMS iX APPLICATION • Internal climate concept for accurate measurements in a wide ambient temperature range and under changing ambient conditions • Protected from vibration by internal dampers and external damping options • High measurement accuracy even in a low measurement range • Low span and zero drift for long measurement intervals • Special “Hybernate” mode to reduce warm-up time BENEFITS AT A GLANCE • Wide operating temperature range and high accuracy even in changing ambient conditions • Robust against vibration through internal dampers and external damping options • High measurement accuracy even in the low measurement range • Low span and zero drift for long measurement intervals • The GAS PEMS iX allows in addition to measure the CH4 concentrations Measurements with portable emission measurement systems (PEMS) on the road are an efficient way to keep the development effort at a reasonable level even as the requirements for fuel economy, emissions and customer expectations increase. PEMS systems are also needed for in-use compliance testing where heavy duty vehicle manufacturers have to report compliance with emission standards. Such measurements require robust and compact devices which can withstand rough testing conditions and provide reliable and accurate measurements over long test durations and under changing ambient conditions. MEASUREMENT PRINCIPLE The AVL GAS PEMS/ GAS PEMS iX are compact and robust PEMS devices for obtaining the emissions of vehicles during real life operation on the road. The GAS PEMS measures the THC, NO/NO2 and CO/CO2 concentrations in the exhaust gas of Diesel and Gasoline Vehicles. The GAS PEMS iX also allows the measurement of CH4 concentrations. Reliable test cell analyzers, which are optimized for mobile application, ensure high measurement accuracy. All analyzers are temperature conditioned to achieve reliable measurements even in changing ambient conditions. The GAS PEMS/ GAS PEMS iX is controlled via AVL M.O.V.E System Control, which stores all data and provides interfaces to access e.g. ECU/CAN bus data and additional sensors.
