This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C.

The eTape Liquid Level Sensor is a solid-state sensor with a resistive output that varies with the level of the fluid. It does away with clunky mechanical floats, and easily interfaces with electronic control systems. The eTape sensor's envelope is compressed by the hydrostatic pressure of the fluid in which it is immersed.

 A magnet on the inside of a cylinder, or on the other side of a motion device will guide the built-in magnetics of the MagnetoPot for position output as a voltage divider. As opposed to a Reed Switch, which gives simply “open” or “close” signals, the MagnetoPot gives the full linear travel as a magnetic sensor.
