    • A fluid detection system comprises a liquid sensor, an air pump and an atmospheric pressure sensor encased within an air and water permeable casing defining an enclosed air space. The pressure sensor acquires pressure samples within the casing, the air pump expelling additional gas into the casing. In response to determining a flood-status or a non-flood-status state of the fluid detection system and comparing the samples, a failure of the fluid detection system or an immersion of the fluid detection system in fluid is determined. In some embodiments, failure is determined if a second sample is greater than a first sample in a non-flooded state, and in others immersion is determined if a second sample is greater than a first sample value and the determined state is flooded. In some examples, gas is expelled across a liquid detection surface and a third sample value is acquired.
    • 流体检测系统包括液体传感器,空气泵和大气压力传感器,其被封装在限定封闭空气空间的空气和水可渗透外壳内。 压力传感器获取壳体内的压力样本,空气泵将额外的气体排出到壳体中。 响应于确定流体检测系统的洪水状态或非洪水状态状态并比较样本,确定流体检测系统的故障或流体检测系统浸没在流体中。 在一些实施例中,如果第二样本大于非淹没状态的第一样本,则确定故障,而在另一个实施例中,如果第二样本大于第一样本值并且确定的状态被淹没,则确定浸没。 在一些实例中,气体通过液体检测表面排出,获得第三样本值。
