Leakage sensors are designed to detect liquids in containments, pump sumps, etc.

A leak below the liquid level in a tank will be  detected. They give no indication about the tightness of the secondary containment.


Liquids with a flash-point above > 55°C
e.g. heating oil, Diesel, engine oil

Different sensors available:


Capacitive sensor KS

min. liquid level: < 5 mm


Capacitive sensor KVS

min. liquid level: < 1 mm

Conductivity sensor LS

min. liquid level: < 3 mm

Floating switch

min. liquid level: ca. 3 cm
