Specifications
The Bently Nevada 330878-X1-00 MOD:177889-01 is a DIN-mount Proximitor Sensor in the Bently Nevada 3300 XL 50 mm Series. It conditions the signal from a compatible 50 mm proximity probe and extension cable for long-range differential-expansion or rotor-expansion measurement on large steam-turbine generators. The Bently Nevada 330878-X1-00 MOD:177889-01 provides a 27.9 mm linear range, 394 mV/mm nominal scale factor, SpringLoc field terminals, and improved RFI/EMI immunity.

FAQ
What does the X1 portion of 330878-X1-00 indicate?
The final digit 1 identifies DIN mounting. The X character does not specify the 5 m or 9 m system-length digit, so that length must be confirmed from the installed system.
Does this Proximitor Sensor include a probe or extension cable?
No. It is one component of a 3300 XL 50 mm system and must be matched with the correct 50 mm probe and extension cable.
What measurement range does the system provide?
With compatible system components and the specified target, the official datasheet gives a 27.9 mm (1100 mil) linear range.
Can it replace a legacy 7200 50 mm system component by itself?
No. Baker Hughes states that the probe, extension cable, and Proximitor Sensor must all be replaced with 3300 XL 50 mm components during an upgrade.
Can Moore Automation help confirm compatibility before shipment?
Yes. Moore Automation can review the complete installed system length, mounting format, probe and cable part numbers, and provide available inspection photographs.
