Liquid Level Switch
Multi-Point Output Type

Liquid Level Switch

Multi-Point Output Type CLS Series

Detect liquid level at 4 points with slim electrodes.
A single amplifier detects the liquid level of four positions!

Slim type
Attached with sapce-saving is possible due to the slim 2.0 mm thickness of the sensor part.
Flexible
Mountable even on curved surfaces (Φ30 to flat surface)
Without touching
The electrode is mounted from the outside of the pipe/tank and the detection is made without touching the liquid, so there is no risk of contaminating the liquid or corroding the electrode.
4CH Multi-head　
A single amplifier can be used to connect four electrodes. Since each head is separate, it can be used regardless of the position of the electrodes.
Compatible with non-transparent vessels
Capable of detecting even if the pipe/tank is non-transparent. (Only non-metallic containers can be detected.)
