Capacitance level switches

YAL/YAE series

New products that have revolutionized the concept of conventional capacitance level switches

Ideal for detecting liquids, slurries, corrosive liquids, powder, and granulated materials. Capacitance level switches that can be used in harsh environments.
(YAL is Non-explosion proof type. YAE is Explosion proof type.)
* YAE (explosion-proof types) obtained ExiaⅡCT6. t also complies with the international standard IEC explosion-proof standard (IECEx certification). It also complies with China explosion protection, South Korea explosion protection and Taiwan explosion protection.
*YAE series obtained NK ship class standard certification.
*YAL series (when the power supply is 24VDC used in the integrated sensor) has obtained the CE marking.

It can also detect interfaces and foam, in addition to liquid levels.
Various models are offered, including super high temperature types, compact and flat types, and pipe line types. Click here to see their features.

Features, keys

High sensitivity, high performance, and compact
Employment of the latest technology allows the products to provide high function and compactness. A variety of functions are included for detecting liquids, powder, and granulated materials in production fields.
Provides stable detection even in harsh environments
Can be used in harsh conditions such as high and low temperatures and high pressures, vacuum, vibration, and static electricity. Detect (integrated the sensor and in the case of 24VDC using),accurately in spite of strong adhesion and material attachment.
lower power consumption eco-design
The power needed to drive the sensor has been decreased and it contributes to decreased costs and an improved ecology. This ecology design reduces costs 50% when compared with conventional models.
Various functions and free-range power supply are provided (DC power supply is also available)
Equipped with various functions including free-range power supply (20 to 250VAC/DC), a delay function, and a fail-safe function.
Obtained the CE marking
YAL series (when the power supply is 24VDC used in the integrated sensor) has obtained the CE marking.
* Please specify if you are looking for a CE compliant product.
Complies with various certification (YAE series)
・Acquired domestic explosion-proof (intrinsically safe explosion-proof) Exia II CT6.
・Complies with the international standard IEC Explosion Proof (IECEx) *. It is also complies with China Explosion Proof (GB certification and CCCEx certification) *, South Korea Explosion Proof (KOSHA) and Taiwan Explosion Proof (TS).

Usages, use examples

Can detect almost all materials including liquids, powders, and granulated materials.

Detects powders and granulated materials (resin powder, resin pellets, cement, foundry sand, wheat flour, iron oxide powder)
Detects liquids (water, oil, kerosene, gasoline, alcohol, paint, slurry, adhesive agents, chocolate, etc.)
Detects viscous, high conductive, and adhesive substances (sludge, excrement, seawater, soy sauce, caustic soda, carbon, etc.)
Detects foam, detects liquid level not counting foam
Detects the interface between oil and water
For areas that require an explosion proof device (explosion proof certification obtained in Japan, and China. Contact us as for the Korean explosion-proof approval information)
