The Siemens 3UG5207-2F is a 2-pole wire electrode for level monitoring, 500 mm long with Teflon insulation — a direct-fit probe for conductive liquid level sensing in tanks, wells, or sumps where chemical resistance and dielectric strength matter.
RoHS compliance is confirmed since 30-09-24, and REACH Article 33 duty-to-inform documentation is available — covering the substance restrictions required for EU-market installations and pharmaceutical GMP validation.
What the construction means for fit
The 500 mm probe length suits medium-depth tanks (typical for coolant sumps, wastewater basins, or process vessels up to about half a metre). Teflon (PTFE) insulation provides broad chemical resistance — compatible with aggressive media such as acids, caustics, and many solvents that would degrade PVC or polypropylene probes. As a 2-pole wire electrode, it connects directly to a compatible level relay (e.g. Siemens 3UG4 series) without an intermediate converter. The wire construction allows bending into the tank entry, though the Teflon jacket should not be kinked sharply.
