Wide spectrum of sensors is available in the market and commonly, they are classified based on the specific application of the sensor. Sensor used for measuring humidity is termed as humidity sensor, the one used for measurement of pressure is called pressure sensor, sensor used for measurement of displacement is called position sensor and so on though all of them may be using the similar sensing principle. In a similar fashion, the sensor used for measurement of fluid levels is called a Level Sensor.
Quite obvious from its name, Level Sensor are used to measure the level of the free-flowing substances. Such substances include liquids like water, oil, slurries, etc as well as solids in granular/powder form (solids which can flow). These substances tend to get settled in the container tanks due to gravity and maintain their level in rest state. Level Sensor measure their level against a pre-set reference.
Shanghai Yuanben Magnetoelectric Tech. Co., Ltd., established in 2001, is a professional company, engaged in the design and production of magnetic sensors As the pioneer of the magnetic switches sensor, including liquid level switches, flow switches, pressure switches, SS Level Switches, explosion-proof temperature switches, antifreeze switches, temperature transmitters, flow sensors.
