The Bently Nevada 330878-X1-00 belongs to the proven 3300 XL series. This 50 mm Proximitor Sensor measures vibration and position without contact. Its thin design specifically supports high-density DIN-rail mounting.
Additionally, the sensor provides excellent RFI/EMI immunity. This feature prevents nearby high-frequency radio signals from affecting transducer readings. SpringLoc terminal strips require no special tools. Therefore, field wiring becomes faster and more robust.
The 330878-X1-00 comes in two DIN mount options:
X1 = 51 : 5.0 metres (16.4 feet) system length, DIN rail mount
X1 = 91 : 9.0 metres (29.5 feet) system length, DIN rail mount
Both configurations use the same electrical specifications. Choose the cable length that best fits your machine layout.
The Bently Nevada 330878-X1-00 accepts one noncontacting 3300 XL 50 mm probe and extension cable.
Power requirement ranges from -17.5 Vdc to -26 Vdc without barriers at 12 mA maximum consumption. With barriers, use -23 Vdc to -26 Vdc.
Operation at a voltage more positive than -23.5 Vdc may reduce the linear range.
Output resistance is 50 Ω.
Extension cable capacitance measures 69.9 pF/m (21.3 pF/ft) typical.
Factory calibration is set to AISI 4140 steel. However, calibration to other target materials is available upon request.
The 330878-X1-00 uses A380 aluminum for its Proximitor Sensor housing.
Operating temperature ranges from -51°C to +100°C (-60°F to +212°F).
Storage temperature ranges from -51°C to +105°C (-60°F to +221°F).
These wide limits make the sensor suitable for harsh environments like turbines, compressors, and large rotating machinery.
Unlike panel mount versions, this model is optimized for DIN-rail installation. The slim Proximitor Sensor housing fits easily into crowded cabinets. Consequently, you can mount multiple sensors side by side without spacing issues.
SpringLoc terminal strips simplify electrical connections. Furthermore, no special tools are needed for wiring. This saves significant installation time in large systems.
The 330878-X1-00 carries the "00" approval option, meaning no agency certifications.
Nevertheless, it still provides strong RFI/EMI immunity. Internal Bently Nevada quality standards remain fully applied.
If you require CE or other formal approvals, select a different approval option code such as "05".

1. What is the difference between 330878-X1-00 and panel mount versions?
The 330878-X1-00 uses DIN rail mount instead of panel mount. Otherwise, electrical specifications and performance are identical.
2. Can I change the cable length after purchase?
No. The system length is fixed at either 5.0 or 9.0 metres. Use the specified extension cable to maintain 69.9 pF/m capacitance.
3. Does this sensor work without agency approvals?
Yes. The "00" option means no formal certifications like CE. However, the sensor still meets Bently Nevada's internal quality and RFI immunity standards.
4. What voltage supply does the 330878-X1-00 need with barriers?
With barriers, supply between -23 Vdc and -26 Vdc. Operating above -23.5 Vdc may reduce the linear measurement range.
5. How do I mount this sensor in a dense cabinet?
Thanks to its thin A380 aluminum housing and DIN rail design, you can mount multiple units side by side. SpringLoc strips make wiring easy even in tight spaces.
