概述

The newest automobiles are required to have good environmental performance and fuel-saving functionality. Powerful, fuel-saving, low-emissions diesel engines have particulate filters and oxidation catalysts for purifying NOx and soot in their exhaust systems. In order to maintain the performance of these systems, exhaust gas pressure is monitored by differential pressure sensors. The Stimulus Test Cell HA7300 is a test cell which provides an environment for high-speed, highly accurate temperature and pressure test of differential pressure sensors, utilizing Advantest's unique temperature control unit with simultaneous temperature control for 8 devices, as well as a newly developed 2Port pressure controller and pressure application nozzle.
