The 3300 XL sensor shares the older Proximitor four-hole footprint when the correct mounting base is used. Because option 52 supplies no mounting hardware, the existing base, isolation and fasteners form part of the outage preparation.

A compatible 5.0 m probe can connect directly to this 5.0 m Proximitor Sensor. The exact probe family and connector arrangement still need to match the installed 3300 XL 8 mm channel.

It should not be reused unchanged. This 3300 XL 8 mm sensor has a 2.0 mm nominal linear range and a 7.87 V/mm nominal scale factor, so the monitor setup and completed 5.0 m chain need to match the XL8 system.

The proposed 320 m run exceeds the published 305 m maximum between the Proximitor Sensor and monitor. Longer field wiring can introduce high-frequency rolloff, so the layout needs a shorter run within 305 m using the recommended three-conductor shielded triad and 16–24 AWG conductors.

The sensor’s maximum current consumption is 12 mA, so a 10 mA circuit does not provide the published capacity. The barrier and supply need a current rating that covers 12 mA while keeping sensor voltage within −23 to −26 Vdc.

The 3300 XL Proximitor Sensor is designed with high radio-frequency immunity and is documented for use in fiberglass housings without adverse effects from nearby radio signals. Its CE-related RFI/EMI performance does not require special shielded conduit or a metal housing solely for that reason; other site protection requirements remain separate.
