Description

The Bently Nevada 330172-00-20-90-01-05 is a 3300 5mm proximity probe from the 3300 series eddy current transducer system, manufactured by Bently Nevada (a Baker Hughes company). It features a 1/4-28 UNF-2A mounting thread and is equipped with stainless steel armor for mechanical protection of the probe cable.

This probe is the armored variant (330172) of the 3300 5mm proximity probe series, distinguished from the non-armored version (330171) by the inclusion of flexible AISI 302 or 304 stainless steel cable armor with an FEP outer jacket. The armor provides enhanced protection against abrasion, crushing, and other mechanical damage in harsh industrial environments.

The Bently Nevada 330172-00-20-90-01-05 is a 3300 Series 5 mm proximity probe designed for non-contact measurement of shaft vibration, position, and displacement in rotating machinery. This model features a 1/4-28 UNF threaded probe body with stainless-steel armor protection for enhanced mechanical durability in demanding industrial environments. The probe is commonly used in machinery condition monitoring and protection systems installed on turbines, compressors, pumps, motors, and generators.

The armored cable construction provides additional resistance against abrasion, vibration, mechanical damage, and harsh operating conditions. As part of the 3300 5 mm Transducer System, the probe works with compatible extension cables and Proximitor sensors to deliver accurate shaft motion measurements for predictive maintenance and machine protection applications.

The 330172-00-20-90-01-05 Bently Nevada 3300 5mm Probe, 1/4-28 UNFthread, with armor may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.
When combined with a 3300 XL Proximitor Sensor and 3300 XL extension cable, the system provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface. The system linear range is 2 mm (80 mils), with an incremental scale factor of 7.87 V/mm (200 mV/mil) and a recommended gap setting of 1.27 mm (50 mils). The frequency response extends from DC to 10 kHz (+0, -3 dB) with up to 305 metres (1,000 feet) of field wiring.
 
The probe operates over a temperature range of -35 °C to +177 °C (-31 °F to +351 °F). The temperature stability ensures that the incremental scale factor remains within ±10% of the nominal value across the full operating temperature range. The extension cable is rated from -51 °C to +177 °C (-60 °F to +351 °F).

Seat the O-Ring: Place the companion elastomer O-ring directly over the top 2-pin MIL-C-5015 connector on the transducer head.
Position the Adapter Seal: Lower the internal adapter seal over the O-ring.
Secure the Internal Threads: Tighten the adapter seal using the factory-applied thread-locker to a target range of 3.4 to 5.6 N⋅m (30 to 50 in⋅lbf). Apply a thin layer of silicon grease to the external threads of the adapter seal to facilitate smooth alignment.

Technical notes

The probe has zero unthreaded length (0.0 in) and an overall case length of 2.0 inches (50.8 mm), making it suitable for installations where the probe threads directly into a mounting location without an extended unthreaded section. The total cable length is 9.0 metres (29.5 feet), with a length tolerance of +20% and -0%. The armor length is 300 mm (11.8 in) shorter than the total cable length, leaving a non-armored portion at the connector end.

FAQs

  • What is the standard GAP voltage for this probe?

    +
    The probe gap is measured as a negative DC voltage. For standard Bently Nevada 3300 Proximity Transducer Systems, the ideal commissioning gap voltage is typically set to -10 VDC. This corresponds to a physical distance of 1.27 mm (50 mils) from the probe tip to the conductive target..
  • Why is my sensor showing a high gap voltage?

    +
    If your gap voltage is reading between -13 VDC and -14 VDC, it usually means the sensor is too far from the target. If it reads 0 VDC to -2 VDC, it might mean the machine was damaged, the probe has contacted the shaft, or there is an electrical fault (like a broken wire).
  • What target material must be used?

    +
    To achieve accurate vibration measurements, the system is calibrated by the factory for standard AISI 4140 steel. Using this probe on non-conductive surfaces, or different metals without factory-requested custom calibration, will result in erroneous readings.
  • What is the 330172-00-20-90-01-05 ?

    +
    The Bently Nevada 330172-00-20-90-01-05 is a 3300 5 mm Armored Proximity Probe designed for non-contact vibration and position measurements on rotating machinery.
