LEVEL SENSORS
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.
Level sensors are used for example in water purification plants and also in the fuel tanks of reserve power stations.
