Is possible. Liquid level detection multi-point with one (1 to 7 points). High temperature specification, also corresponds to the explosion-proof.

Multi-point (1-7 points) detectable made of SUS float type level sensor

  • Up to 7 points the liquid surface can be detected with a single.
  • In addition to the standard specification, it offers a wide range of types to suit the conditions of use.
    ■ It corresponds also to the intrinsic safety in combination with the relay barrier.

By the float size and detection points, you can choose two types of the following

  • YF-RS type: Normal float: liquid level detection possible up to a maximum of 7 points

Others, corresponds to the special specifications (material, L-shaped, surface treatment, high pressure support, etc.).

1. Multi-point (multi-point) detection
is possible liquid level detection of a single multi-point (up to a maximum of 7 points).
Normal float: liquid level detection possible up to a maximum of 7 points ⇒ YF-RS type
small float: up to 4-point liquid level detection possible ⇒ YF-RS □ S type

2. have a high durability and reliability, temperature, humidity, and gas impact not subject to an equal
by the adoption of high reed switch durable, and excellent reliability and durability.

3. corresponding to the intrinsic safety explosion-proof structure in combination with the relay barrier

Contact and non-contact  contact
Measuring method  Float type
Explosion proof  No (non-explosion proof) / Intrinsically safe
The size of the tank  Medium-sized (drum size)
Mounting position  Vertical (from above)
Details measurement environment  Water supply control and or drainage control / raw material level control / wide range of liquid (the type of the liquid in the drainage tank is changed to the multi-point of the liquid level control / Bill condominiums of elevated water tank, it may change the electrical properties of the liquid also can be measured) / water and sewage water level monitoring
