柴油机微粒过滤器（DPF）中的压差传感器模块
数学压差传感器（MDPT）是专门为测量柴油机微粒过滤器（DPF）中的压差而开发的。MDPT由两个坚固的独立压力传感器组成，可测量过滤器上游和下游的压力。借助微控制器，借助获得专利的数学方法确定压力差。此设置可以额外输出系统压力。MDPT凭借其创新理念，即使在不利的工作条件下，也可以在整个生命周期内提供准确而稳定的测量数据。具有正确配置的压力连接的设计可确保安装防冻。专为多功能车行业而开发，同时也适用于各种工业要求满足EMC/ESD等规范场合的应用。 产品应用 Fields of application Exhaust aftertreatment· Monitoring of diesel particulate filters· Enhanced emissions monitoring (OBD)· Protection of the motor against overpressure 产品特性及参数 Key featuresBenefitsMeasurement via two independent pressure sensor modules· High degree of accuracy due to mathematically calculated and corrected output values· Measurement and output of the differential and system pressure possibleUse of materials resistant to exhaust emissions· Excellent media compatibility· Resistant to corrosion and hydrolysisApplication-specific evaluation electronics· Automobile-tested EMC/ESD durability· Enhanced diagnostic and protective functions Pressure ranges Differential pressure200…800 mbarSystem pressuremax. 10 x differential pressureOverpressure1.5 x system pressureBursting pressure2.5 x system pressureAccuracyTotal error 4) ± 0.2% FS (25…80°C) Environmental conditions Operating temperaturerange -40…125°CMedia compatibilityExhaust, compressed air, diesel fuel, motor oilESD (DIN EN 61000-4-2)8 kV (severity level 4)EMC (ISO 11452)200 V/m (Stripline)150 mA (BCI) 产品规格书下载汽车应用发动机管理；尾气排放重型设备应用发动机管理；尾气排放铁路应用发动机管理；排气系统海洋应用发动机管理电子产品应用工业工业应用仪器仪表信号检测压力；排放处理压力特性低压
