That coil is embedded in the sensing element, a semiconductor made of a metal like tin oxide.
12.
Unlike the vane meter's paddle sensing element, the hot wire responds directly to air density.
13.
Technically, the absorbent material is the sensing element, converting the amount of gas to a strain.
14.
The main difference in working principle between these two cases is the way they apply forces to the sensing elements.
15.
The pressure-sensing element of a pressure switch may be arranged to respond to the difference of two pressures.
16.
The output signal is proportional to the angular rate due to internal integration that occurs inside of the sensing element.
17.
The sensing elements are in close proximity and in good mutual thermal contact, to avoid differential signals caused by temperature differences.
18.
Since only one sensing element contacts the powder, bridging between two probe elements is eliminated and media build-up is minimized.
19.
The actual number of light-sensing elements depends on the sensor technology used and the relative influences of the marketing and engineering departments.
20.
When this happens the electrolyte flows through the sensing element, which is rigidly fixed inside the channel, and the motion is detected.
