Meters for supervising changes in substance characteristics

YOL series

Liquid type discrimination sensor that detects interruption of liquid supply in piping and contamination of other liquids.
Optimum for detecting various substances and for controlling quality.

Determine if two types of liquid (liquid A or liquid B) are flowing in the pipe. Can be detected when nothing is flowing or when the liquid is interrupted.

• 

By measuring the difference in the "dielectric constant" of the liquid, it is possible to discriminate the flowing liquid and detect the empty state in-line. Also can be used as an interface level switch.

Features, keys

1. Canceling the adhesion of liquid
   Even if the flowing liquid adheres to the sensor part, the adhered part is canceled and false detection does not occur.
2. Supports harsh conditions such as high temperature and high pressure
   Supports difficult usage environments such as high temperature, high pressure, low temperature and vacuum.
3. Free-range power supply and can be able to sequencer output
   Wide range of AC / DC 20-250V free power supply is adopted. Not only contact output but also various non-contact outputs are supported.
4. Supports delay function and fail-safe in case of failure
   A delay function is also installed, and a fail-safe function is also installed as standard in case of failure.
5. Intrinsically safe explosion-proof
   Intrinsically safe explosion-proof products (Exia�UBT5Ga conforming to international standards) are also available.

Usages, use examples

• Oil / water discrimination switch (detects when water is mixed or interrupted)
• Can also be used as an oil leak detection sensor for oil barriers, etc.　
• In addition, discrimination of liquids with different dielectric constants (cleaning liquid and water, etc.)
