330850-91-00 specifies a 3300 XL 25 mm Proximitor Sensor configured with a 9.0 m system length and DIN rail mounting, intended for installations requiring no hazardous area certifications.
This sensor forms an integral part of the 3300 XL 25 mm Proximity Transducer System, which is designed for non-contact, large-target eddy-current displacement measurements, specifically for steam turbine differential expansion (DE) and casing expansion. By processing the high-frequency RF signal from a 330851 proximity probe and 330854 extension cable, the Proximitor sensor provides a scaled analog output of 0.787 V/mm (20 mV/mil). Compared to panel-mount or alternative 5.0 m configurations, this 9.0 m DIN-mount version offers extended system reach and convenient standard DIN rail installation inside local instrument enclosures.

For optimal installation of the 330850 DIN-mount Proximitor sensor, ensure it is secure on a standard 35 mm DIN rail. Secure the field wiring terminals (0.2 to 1.5 mm2 or 16 to 24 AWG) using a shielded triad cable with a maximum length of 305 metres (1000 feet) to the monitoring system. Keep the coaxial connectors between the extension cable and the probe finger-tight, or torque to a maximum of 0.565 N-m (5 in-lb). The Proximitor must be housed in a clean, dry enclosure providing at least IP54 protection to prevent exposure to moisture and contamination.
This device complies with the European CE mark requirements.
