Vibrating Fork Level Switch for Powder

Product Description

SMARTsaa offer most Compact and miniature Vibrating Fork Level Switches with corrosion resistant stainless steel enclosure for free flowing powders and granules. Due to its compact structure it can be used in small hoppers and chutes. Wetted parts are of high polished, non corrosive SS 316 hence suitable for food grade and pharmaceutical application. Find application in food, packaging, Cement, steel & power generation industries for monitoring level of ash, cement & plastic granules. This switch can be used for overfill detection, lower level of material in hopper.

Application

Level detection of cement in hopper

Powder level detection in tanks

Plastic granule level detection in storage hoppers 

Level detection in ash and cement unloading chutes

Salient Features:

Stainless steel housing with DIN connector, degree of protection IP67

Easy to install even at points difficult to access due to compact design

Rugged stainless steel housing (316L)

OPERATING PRINCIPLE:

Vibrating Fork Level switch contain Piezo-electric crystal in the probe, which causes the fork to vibrate. It detects the presence or absence of material and actuates a solid state O/P. 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 O/P to change state. When fork is free from material relay reverts to its normal condition
