ꄴ前一个： IPS压力传感器 - 工程机械/H2，CNG和LPG应用/重型设备液压压力应用

ꄲ后一个：氢气（H2）压力传感器 - LPS，MPS，HPS - 用于氢气系统和储罐

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。
