Solid-state eTape sensors make it easier to monitor the height of fluids — liquid or a fine powder — in a container. Placed vertically in a container, eTape senses the hydrostatic pressure applied by the fluid to the portion of the sensor that is submerged.
eTape sensors output a value in a continuous range corresponding to the fluid level along the entire length of the sensor, ideal where a single-point fluid level detection is not enough. The slim, low-profile sensor has no moving parts and fits unobtrusively where there may not be enough room for mechanical float devices.
eTape Liquid Level Sensors produce a variable resistance output. If your application is more suited to monitoring a voltage output, you may want to use the sensor with the optional eTape 0-5VDC Linear Resistance to Voltage Module.
- Rated for use with non-corrosive, non-edible fluids
