MEDER electronic
LS01 Series
Level Sensors with
Magnetic Floats
DESCRIPTION
Standard liquid level sensor. The sensor has to be
mounted vertically for best results.
Two versions are available:
PP
(Polypropylene) for water applications and
dilute acids
PA
(Polyamide) for use in oil, gasoline (petrol) and
brake fluid
The standard termination is a PVC single wire with
a cross section of 0.25 mm
2
and a length of 500
mm. The cable can be modified on request.
