Multiple point (1 to 4 points) liquid level detection is possible with one unit. High temperature specification, also correspond to explosion-proof specifications.

Multi-point (1-4 points) detectable SUS made small float-type level switch

  • Small float switch without terminal box.
  • Multiple point (1 to 4 points) liquid level detection is possible.
    ■ Combined with the relay barrier also supports intrinsically safe explosion protection.

By the vertical mounting and horizontal mounting, you can choose two types of the following

  • YF-GS □ S type 🙁 vertical mounting) liquid level detection can be up to a maximum of 4 points

other, special specification, also corresponds to the high-pressure specifications, offers, such as explosion-proof.

1. by the vertical mounting and horizontal mounting, you can choose two types of following
vertical mounting type: up to 4-point liquid level detection possible ⇒ YF-GS □ S type
Horizontal mounting type: liquid level detection can be up to 2 points ⇒ YF- GS □ L type

2. It is durability and reliability
temperature, humidity, not affected by the gas, and the like.

3. You can select the material and structure in the nature or conditions of use of the corresponding measurement liquid
oil-free processing, electrolytic polishing, buff finish (# 400), such as bonding (between the float stem connection)

4. nature in combination with the relay barrier Corresponds to safety explosion-proof structure
