Data Sheet

Description
The eTape chemical sensor is a solid state, continuous (multi-level) fluid level sensor with a Teflon
(FEP) jacket that is rated for use in chemical, petroleum and food safe applications. The eTape
sensor is manufactured using printed electronic technologies which employ additive direct
printing processes to produce functional circuits.
Theory of Operation
The eTape sensor's envelope is compressed by hydrostatic pressure of the fluid in which it is
immersed resulting in a change in resistance which corresponds to the distance from the top of
the sensor to the fluid surface. The eTape sensor provides a resistive output that is inversely
proportional to the level of the liquid: the lower the liquid level, the higher the output resistance;
the higher the liquid level, the lower the output resistance.
