TheeTap 12'' solid stateliquid level sensor. It has a resistive output whose value changes depending on the liquid level. The resistance range foran empty container is 2250 Ωand for afullcontainerit is400 Ω. The sensor can be combined with electronic control systems. The length of its active part is320.7 mm, and the total dimension is 358 mm.
The value on the resistive output is inversely proportional to the height of the liquid.
The cover of the eTap sensor compresses under the hydrostatic pressure of the fluid in which it is immersed. This causes a change in resistance, which corresponds to the distance between the top of the sensor and the fluid level. The value on the resistive output is inversely proportional to the height of the fluid - the lower the fluid level, the more the resistance increases; the higher the level, the resistance output decreases..
