Option 90 (9.0 m system length, panel mount) and Option 00 (no required approvals) specify this 3300 XL 25 mm Proximitor Sensor configuration — 330850-90-00.
This sensor processes eddy-current signals from a 3300 XL 25 mm proximity probe and extension cable to measure large-target shaft displacement, differential expansion, or thrust position. It operates with a nominal scale factor of 0.787 V/mm (20 mV/mil) over a 12.7 mm (500 mils) linear range. This specific 9.0 m panel-mount sensor configuration is intended for installations where the total combined probe and extension cable length equals 9.0 meters. The unit features built-in SpringLoc terminal strips for field wiring connections, providing RFI/EMI shielding without specialized tools.
