Float type level switches

YF-RS

Float type level sensor made of SUS that can detect multiple points

Other types than standard reed switches are also available to match the specific use conditions.

• 

Model with a small float (YF-RS□S), and explosion proof versions are available. Changes can be made in the specifications (coupling method, material, L shape, surface processing, resistant to high pressure, etc.).

Features, keys

1. Multi-point detection
   One unit can detect liquid levels at a maximum of 7 points.
   
2. The unit is durable, highly reliable, and is not affected by temperature, humidity, or gases
   The unit is very reliable and durable thanks in part to the use of the highly reliable reed switch.
   
3. The unit is intrinsically safe and explosion-proof due to the combination of the reed switch and relay isolator.
   
4. The following two types can be selected for normal and small floats
   Normal float type: Can measure liquid levels maximum of 7 points ⇒ YF-RS
   Horizontal installation type: Can measure liquid levels maximum of 4 points ⇒ YF-RS□S

Usages, use examples

• Detect levels of water, oil, and various liquid chemical agents
• Control liquid levels at multiple points
  Ex.: Can be used with various applications, including controlling pumps, setting upper and lower limit alarms, and contributing to decreasing users’ total costs.

Standard specifications

Connection

*1: The Ln dimension means a length from the set position to the bottom of the screw.
*2: The L dimension means the total length from the bottom of the screw.
*3: Setting distance dimensions refers to the minimum dimension when two stoppers are used.
*4: The L-Ln dimension refers to the difference between the final setting position (Ln) and total length.
Note: The values for *3 and *4 are true when the specific gravity of the liquid is 1.0.
