Detect the liquid level inside transparent tubes.

Strap the Fiber Unit to a tube with band.

Tube-mounting Types

Detect the liquid level by direct contact with

the liquid.

This model has excellent chemical-resistance

because the Fiber Unit is covered in fluororesin.

Liquid

•

Fiber Units for detecting liquid levels are available in two types: for tube

mounting and liquid contact.

If the incident light level is too high, perform power tuning or use the ECO mode to decrease the incident level.

The applicable range is the same whether an E3X-HD series or E3NX-FA series is used.

When using a Fiber Amplifier Unit in giga-power mode, level detection may not work depending on the tube diameter. Make sure to confirm operation with the actual tube.

The bending radius of the sensing section (except for the unbendable section) is 40 mm, and the bending radius of the fiber is 25 mm.

Features

When bubbles and the water

droplets are generated

Multilevel installation in limited space

Mounting on large diameter tubes

This is a Through-beam Model, so the incident light will differ greatly between with and without

of liquid.

It also uses an area beam, which is less prone to false detection by bubbles and droplets.

This model has no restrictions on the tube diameter, so it can be mounted on many different

tube sizes.

It also uses an area beam, which is less prone to false detection by bubbles and droplets.

This model is suitable for mounting at multilevels because of the thin type (height: 10 mm).

Designed for Safe Residual quantity detection (E32-A01 only)

The E32-A01 Fiber Unit is designed to default to the same output

as for liquid absent in the event of a failure, such as when the fiber

breaks. This makes it suitable for residual quantity detection.

If the failure goes unnoticed, this failsafe design will prevent false

detection of liquid when there is no liquid present.
