Environmental and approval information that must be checked against the complete ordering code and installation area.
The complete 3300 XL 50 mm system is designed for harsh steam turbine differential expansion environments. The official datasheet specifies probe continuous operation up to 200 degrees C and intermittent exposure up to 250 degrees C. System performance limits depend on the temperatures of the probe, extension cable and Proximitor Sensor. European CE compliance is stated for the product family; the exact approval option for this X0-00 MOD unit is subject to verification.
Practical checks for matching system length, mounting style, target and field installation requirements.
Confirm the complete 330878-AA-BB ordering code before selection. Official options define 5 m or 9 m system length, panel or 35 mm DIN-rail mounting, and no-approval or multiple-approval versions. The combined probe and extension-cable length must equal the Proximitor Sensor total system length. Target material, target diameter, mounting geometry, barriers and field wiring can affect performance.
