The Bently Nevada 330878-90-00 is part of the high-performance 3300 XL series. This 50 mm Proximitor Sensor measures vibration and position in rotating machinery without contact. Its thin housing fits both high-density DIN-rail installations and traditional panel mount setups.
Moreover, the sensor offers excellent RFI/EMI immunity. Therefore, nearby high-frequency radio signals cannot disrupt the transducer system. The 3300 XL Proximitor Sensor also uses SpringLoc terminal strips. These strips need no special tools, so field wiring becomes faster and more reliable.
The Bently Nevada 330878-90-00 accepts one noncontacting 3300 XL 50 mm probe plus an 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, you can request calibration to other target materials.
The 330878-90-00 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 allow reliable use in harsh industrial environments like turbines and compressors.
This Proximitor Sensor includes a 9.0 metres (29.5 feet) system length with panel mount option.
SpringLoc terminal strips simplify wiring. Consequently, you save installation time and reduce errors.
Furthermore, the slim profile supports dense DIN-rail mounting. Alternatively, you can install it in a conventional panel configuration.
For best results, always match the target material to the calibration. Use the recommended extension cable to maintain proper capacitance.
The 330878-90-00 carries the "00" option, meaning no agency approvals.
Even without formal approvals, it still provides strong RFI/EMI immunity. It also meets internal Bently Nevada quality standards.
If you need CE or other approvals, choose a different approval option code like "05".

1. Can I use the 330878-90-00 with a different target material?
Yes. The factory can recalibrate this 3300 XL Proximitor Sensor to other materials. Contact your supplier to arrange special calibration.
2. What voltage supply does this sensor need with barriers?
With barriers, you must supply between -23 Vdc and -26 Vdc. Operating above -23.5 Vdc may reduce the linear measurement range.
3. Does the 330878-90-00 have CE or other approvals?
No. The "00" option means no agency approvals. However, the sensor still has strong RFI immunity. Choose a different approval code if certifications are required.
4. How do I mount this sensor in a tight cabinet?
Thanks to its thin A380 aluminum housing, you can mount it on high-density DIN rails. SpringLoc strips also make wiring easy in confined spaces.
5. What is the total system length of this model?
The Bently Nevada 330878-90-00 has a fixed 9.0 metres (29.5 feet) system length. Use the correct extension cable to keep 69.9 pF/m capacitance for accurate readings.
