Ring-21 Compact Liquid Level Switch

Ring-21 is an economical compact tuning fork liquid level switch with maximum reliability and safety. It is also based on the principle that vibrating frequency changes when tines are immersed into measured medium. It is designed with a lightweight compact structure with the fork body 38 mm long, total length is 160.5mm and maximum diameter 31.5mm. Particularly it is a better choice for small containers or tanks within confined space. The measurable density is as low as 0.7g/cm³.

Same as Ring-11, Ring-21 Compact Liquid Level Switch is based on fork resonant principle. When fork body which vibrates in harmonic resonance immerses into the measured liquid, vibrating frequency of tuning fork will greatly decrease, so does the output of piezoelectric detection device. An integrated circuit is designed to analyze signal from piezoelectric device and output a switching signal.

●　Compact and portable, with overall length 160.5mm, maximum diameter 31.5mm and the fork body only 38mm long.

●　Particularly suitable for pipelines and other applications within constricted space.

●　With CE certificates. Economical, practical and high cost-effective ratio.

●　Highly reliable because of detecting changed of vibrating frequency of the fork.

●　Simple setup, free of maintenance

●　Applications that expecting low cost, in non-explosive environment and within constricted space.

●　Pipelines in pump protection system.

●　Level measurement and control with process temperature not exceeding 150 ℃.
