/ 187 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 viration y 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 Hyernate 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 AS PEMS i allows in addition to measure the CH4 concentrations Measurements with portale 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 epectations 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 AS PEMS/ AS PEMS i are compact and roust PEMS devices for otaining the emissions of vehicles during real life operation on the road. The AS PEMS measures the THC, NO/NO2 and CO/CO2 concentrations in the ehaust gas of iesel and asoline Vehicles. The AS PEMS i 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 amient conditions. The AS PEMS/ AS PEMS i is controlled via AVL M.O.V.E System Control, which stores all data and provides interfaces to access e.g. ECU/CAN us data and additional sensors.
