Product Introduction
Bently Nevada 330180-51-05 is a 3300 XL Proximitor Sensor (conditioner) for 5 mm and 8 mm eddy current proximity probes. It conditions the probe signal to produce an output voltage directly proportional to the distance between the probe tip and a conductive target, enabling measurement of static position and dynamic vibration.
The compact DIN-rail mount design with 5.0 m system length, 7.87 V/mm sensitivity, and built-in electrical isolation supports high-density installations on fluid-film bearing machines. The -05 suffix includes CSA, ATEX, and IECEx approvals, making it suitable for hazardous areas while meeting API 670 compliance.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No output voltage from sensor | Power supply absent or reversed polarity | ✅ High | Measure supply voltage at sensor terminals (-17.5 to -26 Vdc); check polarity | Restore correct power and polarity before replacing sensor |
| Output stuck at 0 V or max | Probe disconnected, damaged, or wrong gap | ✅ High | Verify probe connection; inspect probe tip for damage; measure probe-to-target gap | Reconnect/replace probe or re-set gap before replacing sensor |
| Output noisy or unstable | Loose wiring, broken extension cable, or EMI | ✅ High | Check DIN connections and extension cable continuity; verify shield grounded at one end only | Repair wiring/cable and ground shield properly |
| Output does not match expected distance | Wrong sensitivity setting or incompatible probe | ✅ Medium | Verify sensor sensitivity (7.87 V/mm matches 5/8 mm system); confirm probe is 3300/3300 XL 5 or 8 mm | Replace probe with compatible 3300 XL probe or adjust sensitivity if configurable |
| Sensor overheats or fails quickly | Power supply overvoltage or excessive current | ✅ Medium | Measure supply voltage and current; verify 24 VDC nominal, 140 mA max | Correct power supply before replacing sensor |
| Sensor case corroded or terminals damaged | Harsh environment or moisture ingress | ❌ Low | Inspect case and DIN terminals for corrosion or water damage | Replace sensor if physical damage is evident |
Contact technical support with photos of the sensor label, DIN mounting, probe wiring, extension cable, supply voltage readings, and output voltage under target gap if the fault is still unclear.
Frequently Asked Questions
Can I use 330180-51-05 as a direct replacement for an older 3300 Proximitor sensor?
Yes. The 3300 XL 5/8 mm Proximitor Sensor supports complete interchangeability with all 3300 and 3300 XL 5 mm and 8 mm probes, extension cables, and other Proximitor sensors. The -51-05 suffix adds 5.0 m system length, DIN mount, and multiple approvals.
Is this sensor hot-swappable?
This is a DIN-rail mounted conditioner, not a rack module. You can disconnect and reconnect it on a DIN rail, but you should consider whether the sensor output is live and follow your site’s electrical safety procedure when handling live circuits.
What probes does this sensor support?
It supports all 3300 and 3300 XL 5 mm and 8 mm probes, making it versatile for displacement, position, and vibration monitoring on fluid-film bearing machines.
Why is surplus stock cheaper than factory new?
Surplus parts often come from excess inventory, decommissioned systems, or channel stock. The price is lower, but you still need a clear test record and condition statement (New Original, New Surplus, or Refurbished tested).
What condition should I expect on a surplus unit?
For a credible sale listing, state whether it is New Original, New Surplus, or Refurbished (tested). Buyers in this market want the truth up front, not a vague “used” label.
Does this part fail often?
Not usually. More often, the probe, extension cable, wrong gap setting, power supply issue, or wiring/EMI causes the fault. Always verify probe connection, check probe-to-target gap, and confirm power supply before replacing the sensor.
What certifications does this sensor have?
The -05 suffix includes CSA, ATEX Zone 1, and IECEx approvals, making it suitable for hazardous areas in oil/gas, chemical, and power generation applications.
