柴油機微粒過濾器（DPF）中的壓差傳感器模塊
數學壓差傳感器（MDPT）是專門為測量柴油機微粒過濾器（DPF）中的壓差而開發的。MDPT由兩個堅固的獨立壓力傳感器組成，可測量過濾器上游和下游的壓力。借助微控制器，借助獲得專利的數學方法確定壓力差。此設置可以額外輸出系統壓力。MDPT憑借其創新理念，即使在不利的工作條件下，也可以在整個生命周期內提供準確而穩定的測量數據。具有正確配置的壓力連接的設計可確保安裝防凍。專為多功能車行業而開發，同時也適用于各種工業要求滿足EMC/ESD等規范場合的應用。 產品應用 Fields of application Exhaust aftertreatment· Monitoring of diesel particulate filters· Enhanced emissions monitoring (OBD)· Protection of the motor against overpressure 產品特性及參數 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) 產品規格書下載汽車應用發動機管理；尾氣排放重型設備應用發動機管理；尾氣排放鐵路應用發動機管理；排氣系統海洋應用發動機管理電子產品應用工業工業應用儀器儀表信號檢測壓力；排放處理壓力特性低壓
