Liquid Leak / Liquid Detection Fiber

It corresponds to various liquid events, from the contact (wetted) type to the pipe mounting type, and up to leak detection.

Features
Applications

Detecting liquid level in a tank

Leak detection for use in semiconductor device manufacturing

For detecting the upper limit of liquid surface level, sensor that receives beam when “liquid is absent” is recommended.

The sensor will turn OFF during abnormal conditions (excess fluid, fiber disconnection, etc.)!
Liquid absent: Beam received (Output ON)
Liquid present / fiber is cutoff: Beam not received (Output OFF)

FD-FA93
Strong against air bubbles
Applicable pipe: Transparent pipe, Outer diameter ø8 mm ø0.315 in or more
(When used with the tying bands: o8 to ø80 mm ø0.315 to ø3.150 in)

FD-F41
Standard type

FD-F4

For 1 mm 0.039 in thick pipes manufactured by PFA

For detecting the lower limit of liquid surface level, sensor that receives beam when “liquid is present” is recommended.

The sensor will turn OFF during abnormal conditions (insufficient liquid, fiber disconnection, etc.) !
Liquid present: Beam received (Output ON)
Liquid absent / fiber is cutoff: Beam not received (Output OFF)

FT-F93
Thru-beam

Full-protection type [FD-HF40Y / FD-F41Y (Liquid level sensing)]

Small diameter type(ø4 mm ø0.157 in)
Bends easily with its small bending radius, protective tube is cuttable and extendable

* The range of 50 mm 1.969 in from the fiber tip cannot be cut. Also, fiber length can be extended using MS-FX-02Y (optional).

Full-protection type [FD-F71 (Liquid level sensing)]
SEMI S2 compliant

Detect chemical leaks in semiconductor and LCD manufacturing processes.

Compact, space-saving
Side-mountable fiber head as slim as 10 mm 0.394 in is good to use in confined spaces.
Ideal for use with chemicals and volatile materials
This fiber type sensor is safer to use with volatile materials (SEMI S2 compliant). The fluorine resin fiber head makes it ideal for use with chemicals.

* The range of 50 mm 1.969 in from the fiber tip cannot be cut. Also, fiber length can be extended using MS-FX-02Y (optional).
