MAGNETIC ACTUATED CONTACT USING A COIL SYSTEM |
摘要 |
A potentiometric sensor, comprising: a potentiometer track; a collector track opposite the potentiometer track; a conductive magnetic cushion slider coupled to the potentiometer track and the collector track; and a sealed body housing the potentiometer track, the collector track, and the conductive magnetic cushion is disclosed. The potentiometric sensor may provide a variable output voltage indicative of a level of liquid in a container. The output voltage of the potentiometric sensor may be based on a position of a magnet, which may determine a position of the conductive magnetic cushion or a ferromagnetic spring. The magnet may be outside of the sealed body. As the sensor will be more cost effective and less space consuming, the totally sealed sensor incorporating the conductive magnetic cushion or a ferromagnetic spring may replace many applications that allow a hysteresis of less than 1 mm. Additionally, these applications may be used on rotary systems. |
