WATER WATER LEVEL
Liquid
Various line up for detecting
liquid. You can choose depends
on application.
Liquid level: pipe mount type
You can mount on the pipe, 8~80mm Dia.
NF-DF07 has 18 fiber cores for 8.75mm width to detect liquid level stably.

Liquid level: contact type
It prevents accumulation of liquid at tip of the
sensor head by small protrusion at the tip.
3 types of joint are available;

You can procure ferrule for joint above; NF-DA57
Leakage type
It detects liquid leakage on the surface of flat pan.
When liquid leaked, the light defuses
at the leakage and doesn’t get to
receiver.
The light reflects at the detecting
face and the light comes into
receiver.
