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 uid
The standard termination is a PVC single wire with
a cross section of 0.25 mm2 and a length of 500
mm. The cable can be modied on request.
APPLICATIONS
Liquid container monitoring in household
appliances, automotive applications, test and
measurement, and control technology.
