Semtech - Model Ecostar Plus - Gaseous and Flow Measurement
From Test Cell Emissions Analyzers
The SEMTECH ECOSTAR Plus is a modular, ruggedized PEMS system for Heavy-Duty In-Use testing. The base system is comprised of a Fuel Economy Meter (FEM), a NOx Module, a Power Distribution and Control Module (PDCM), and a flow tube with heated filter (HTF). Each module is designed to function as either a stand-alone analyzer or to mate easily with the others, with interlocking handles, for a stackable system that minimizes lines and cables. An intuitive touchscreen interface can be used for system setup, basic functions, and to display live data.
Product Details
The exhaust is routed from the flow meter to the FEM where a non-dispersive infra-red analyzer measures CO and CO2. A manifold at the top of the module provides a direct connection to the NOx module, for measurement of NO and NO2 using a non-dispersive ultra-violet analyzer. A heated line draws sample directly into the FID, which uses flame ionization to measure total hydrocarbons. The system uses a power distribution and control module which is capable of servicing both gaseous and particulate measurement systems, as well as all available accessories. Several design features ensure a robust and easy-to-use system for rugged applications.
