Omron E32-L25T DATASHEET

Fluid level sensor (fiber pipe type)

E32-L25T

For installation of thin pipe (thick­ness of 10 mm) that can be used
even in combustible atmospheres

● Easy post-installation on unit or pipe using band.

● Affordable pricing makes a big contribution to cost

reduction when upgrading equipment.

● Thin pipe of thickness = 10 mm. Contact mounting is
possible to enable detection of level differences to a
minimum of 4 mm.

● Can also be used in combustible atmospheres.*

* Plastic is used in the lens, unit case, and fiber coating. Avoid contact

with solvents as these will cause corrosion and deterioration (cloud­ing).

• When securing with the band, take care that the fiber is not de­formed.

• If an opaque pipe is used, this may result into incorrect opera­tion.

• Water drops, air bubbles, or clouding in the pipe may cause in­correct operation.

• If the background exerts an effect, use the anti-reflection
sheet (accessory) (see the diagram below). The anti-reflec­tion sheet also serves to prevent shifting due to fiber unit vi­bration.

Binding band

• Do not expose the fiber unit to undo forces such as pulling
or compression (no more than 0.1 Nm).

• The bending radius of the fiber unit should be no less than the
allowed bending radius (both rated and performance).
