LS03

Meder Electronic
LS03 Series
Level Sensors with
Magnetic Floats
DESCRIPTION
Standard liquid level sensor. The sensor has to be
mounted horizontally for best results.
Two versions are available:
APPLICATIONS
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 cable with a
cross section of 0.14 mm2 and a length of 500 mm.
The cable can be modified on request.
• Liquid container monitoring in household
appliances, automotive applications, test and
measurement, and control technology.
