Float type level switches

YFD series
YFD series
Float type level sensor made of SUS that is pressure resistant and explosion-proof

Can measure liquid levels stably in an explosive atmosphere. One switch can measure liquid level at multiple points (a maximum of 7 points).

  • For liquid

Products that conform to the pressure-resistant explosion-proof standard (ExdⅡBT4).

 

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. Safe design that endures harsh tank conditions
    Can be used in various conditions including water-proof housings (protection class IP65), detection section can withstand a pressure of 1 MPa.

  4. Conforms to the pressure resistance and explosion-proof standard (ExdⅡBT4)

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.

*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..
