Level sensors can be divided into two categories: continuous level sensors and limit switches. Continuous level measuring can be executed with different measuring techniques such as hydrostatic measuring, ultrasound or with a capacitative sensor. The resulting output ranges between 0-10V or 4..20mA standard message and some sensors also give digital HART reading.
Dinel level sensors have a three year warranty.
Level sensors are used for example in water purification plants and also in the fuel tanks of reserve power stations.
