inductance sensor
A sensor that measures the change in induction to detect material presence or absence is called a L/C-type type induced capacitance relay. This technology is based on the fact that when a coil inductance change phase, with nearby magnetic material. Inductance sensors are used to detect metallic objects, measure the material thickness and sense the position of parts in machinery. Inductance sensor: Technological features include non-contact measurement, high accuracy and working under harsh environments. Such sensors are immensely popular in many industries such as automotive, aerospace and manufacturing for applications like detecting the presence of parts, counting or liquid level sensing.
