柴油機(jī)微粒過(guò)濾器(DPF)中的壓差傳感器模塊
數(shù)學(xué)壓差傳感器(MDPT)是專(zhuān)門(mén)為測(cè)量柴油機(jī)微粒過(guò)濾器(DPF)中的壓差而開(kāi)發(fā)的。MDPT由兩個(gè)堅(jiān)固的獨(dú)立壓力傳感器組成,可測(cè)量過(guò)濾器上游和下游的壓力。借助微控制器,借助獲得專(zhuān)利的數(shù)學(xué)方法確定壓力差。此設(shè)置可以額外輸出系統(tǒng)壓力。MDPT憑借其創(chuàng)新理念,即使在不利的工作條件下,也可以在整個(gè)生命周期內(nèi)提供準(zhǔn)確而穩(wěn)定的測(cè)量數(shù)據(jù)。具有正確配置的壓力連接的設(shè)計(jì)可確保安裝防凍。專(zhuān)為多功能車(chē)行業(yè)而開(kāi)發(fā),同時(shí)也適用于各種工業(yè)要求滿(mǎn)足EMC/ESD等規(guī)范場(chǎng)合的應(yīng)用。 產(chǎn)品應(yīng)用 Fields of application Exhaust aftertreatment· Monitoring of diesel particulate filters· Enhanced emissions monitoring (OBD)· Protection of the motor against overpressure 產(chǎn)品特性及參數(shù) 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(chǎn)品規(guī)格書(shū)下載汽車(chē)應(yīng)用發(fā)動(dòng)機(jī)管理;尾氣排放重型設(shè)備應(yīng)用發(fā)動(dòng)機(jī)管理;尾氣排放鐵路應(yīng)用發(fā)動(dòng)機(jī)管理;排氣系統(tǒng)海洋應(yīng)用發(fā)動(dòng)機(jī)管理電子產(chǎn)品應(yīng)用工業(yè)工業(yè)應(yīng)用儀器儀表信號(hào)檢測(cè)壓力;排放處理壓力特性低壓
