High resistance point level detection of conductive liquids steam boilers and aggressive media. The 11961Z is a highly resistant probe for applications with aggressive medium thanks to corrosion-resistant materials for rod and insulation. It can be used in steam boilers thanks to ceramic insulation resistant to steam and hot water. Lean selection.

The water level system is employed to monitor and/or regulate one or more operating parameters of the boiler, such as water levels within the boiler. In response to the boiler system testing of low-water cut-off, auxiliary low-water cut-off, and pressure vessel float operation and functionality, the software builds histories and other data compilations.

When the level of water in the boiler drops below a predetermined level, the liquid level sensor deactivates the system in a conventional manner. In the embodiments illustrated, such predetermined low water level is in one instance, the position of the lower end of the pipe (FIG. 2), and in another instance the position of the free lower terminal end of the electrode sensor (FIG. 1).
