This is connected to a sensor that picks up changes in pressure and translates them into electrical signals.

和管道相连的是一个传感器，用来捕获压力改变并将其转换为电信号。

Simply magnetise a spot or, more usefully, many spots, and the spots' status can be detected by measuring the changes they induce in the electrical resistance of a tiny sensor placed nearby.

其方法很简单, 只要对一个点或多个点进行磁化以发挥更大的功效, 然后在其附近放置一个微小的传感器就能检测到它们在电阻下的变化从而得知各点的状态.

Electrical cables plugged in the wrong way would switch the "polarity" of a sensor, causing it to confuse left and right.

如果电缆放置错误将改变传感器的“极性(polarity)”，其后果是混淆了左和右。
