The Siemens SIRIUS 3UG3207-2A is a two-pole wire electrode probe designed for level monitoring, 500 mm long with Teflon insulation. It is part of the SIRIUS product family, which covers industrial control and monitoring components for panel builders and OEMs.
What the design means for fit
The 500 mm probe length with Teflon insulation suits conductive liquid level detection in tanks or vessels where the electrode must withstand corrosive or high-temperature media. Teflon (PTFE) provides chemical resistance and electrical insulation, so the probe can be immersed without risk of shorting to the vessel wall or degrading in aggressive fluids. The two-pole design means it functions as a simple conductivity sensor — when the liquid bridges the two wires, the circuit closes; when the level drops below the probe tip, the circuit opens. No moving parts, no calibration.
Compliance note
The part carries a substance prohibitance date of 05/01/2012, which aligns with RoHS compliance deadlines for the EU market. No UL or CSA listing is stated.
