The latest of the level sensor of intrinsically safe explosion-proof type that inherited the rich features of YAL.

Of conventional electrostatic capacitance type level switch

  • Ideal for detection of liquid slurry, corrosive liquid, granules and interface-foam.
    High temperature, you can use low-temperature, high pressure, even in harsh environments such as vacuum.
    Or attached, such as, to solve the problems, such as a float or electrode type.
  • For most of the measured object, also it was solved drawback of conventional electrostatic capacitance type.
    ■ intrinsically safe explosion protection, acquires the ExiaⅡCT6 of international standards consistent.
    ■ China explosion-proof (NEPSI), also supports the Korean explosion-proof (KOSHA).
  • The sensor section, corrosive liquid correspondence of “tubing type”, the longest 10m correspondence of “wire-type”, “pipeline” of pipe, such as a possible change of the electrode length of “adjustable type” offers a variety of specifications you.

1. powerful adheres cancellation and will detect and
conductive liquid of adhesion and chocolate, such as sludge, also attached, such as ready-mixed concrete OK.
It corresponds to the strong adhesion of the powder particles of adhesion and adhesive.

2. ultra-high temperature, also corresponds to the harsh conditions, such as extremely low temperature
high temperature, high pressure, low temperature, vacuum, vibration, also supports the difficult environment of use, such as anti-static electricity.
To 300 ℃ or more of the ultra-high temperature and -200 ℃ cryogenic correspond.

3. free power of AC / DC, the sequencer output is also available
in a wide range of free power of AC / DC20 ~ 250V, it can be used in countries around the world.
Contact output, of course, also supports such as a variety of non-contact output.

4. rippling and also corresponding to the fail-safe at the time of failure
is also equipped with delay function, also supports waving or chattering.
Fail-safe function for the event of a failure are also a standard feature.

Unit configuration

Unit configuration will be used in connection with “sensor portion” and “barrier part”.
The sensor section, there is a “separation-type” of the amplifier by location and “integrated” built-in amplifier.
