Probe for monitoring liquid

摘要

A probe for monitoring a liquid level has a one-piece insulation sheath extended within the probe casing and positioned far beyond the end of a contact pressure spring that is removed from the liquid. This contact pressure spring has an associated spring abutment formed by either a sleeve or a cap surrounding the insulation sheath. In the probe casing, lengthy sections of insulation are present such that functional interferences are avoided. The probe casing has large-dimensioned ventilation apertures for preventing moisture films.
