Cirrus vibration level switches are best suitable for level sensing of free flowing powders, solid granules or liquids. Its working principle involve sensing of level of media vide vibration technique. The switch consists of a pair of stainless steel tuning forks which upholds vibration creating & sensing element inside it. The electronic circuitry inside switch housing gives an impulse to these vibration sensors causing them to vibrate on a particular resonance frequency which is equal to the resonance frequency of tuning forks. This vibrating frequency causes tuning forks to vibrate free inside the tank when forks are not covered with any media. Once the media such as Solid or liquid, covers the tuning forks, it causes damping of vibrations. This sudden vibration amplitude damping effect of vibrating forks is sensed by an equal circuitry which in turns gives an output electronic signal which in turn actuates a relay. Again when media inside tank un-covers tuning forks, vibration of forks regains its high frequency thus causing de-actuation of relay. Due to its constant vibration of forks these switches inherit self cleaning action and are applicable for both solids and liquids. These switches are best used in feed hoppers, storage bins in various granules & powder handling industries.

Other customized versions are available in long fork lengths, Solid rod probe construction & flexible cable hanging versions for larger tank depths and top mountings


Application:
Free flowing solids, powders, granules, plastic granules, cereals, rice, sugar, sand, fine ores, liquids, medium dense liquids, juices, oil etc.
