Vibrating Fork Level Switch

SMARTsaa make Vibrating Fork Level Switches find application in food , packaging , Cement, steel & power generation industries for monitoring level of free flowing products like fertilizer, food grains, coal, sand, chips, granules etc. Switch is Ideal for products that do not have heavy build-up on fork. Can sense dense materials like cement. It also senses extremely light products like styrene. Not recommended for mud, slurry, sticky material or water with high turbidity.

Vibrating Fork Level switch contain Piezo-electric crystal in the probe, which causes the fork to vibrate at a frequency of 125 Hz. It detects the presence or absence of material and actuates a relay. It gives point output, indicating high & low level alarm. It is having compact and robust design, suitable for side & top mounting. The constant vibration of the fork provides self-cleaning characteristics. The change in vibration is detected by circuit which causes the relay to change state after few seconds delay ( about 2-3 seconds). When fork is free from material relay reverts to its normal condition.

• No calibration required, simple to install.
• Performance independent of material characteristics i.e. change in conductivity, di-electric constant.
• No moving parts, hence no wares and tears.
• Weatherproof enclosure, SS 316 for food industry.
