Bently Nevada 32000-00-00-04-470-01-02 Proximity Probe Housing
Description
Overview
The Bently Nevada 32000-00-00-04-470-01-02 is a metric proximity probe housing assembly from the Bently Nevada 31000/32000 family. These housings are recommended when a proximity probe has to be mounted through the machine case, most often for radial vibration or Keyphasor measurements. The housing gives external access to the probe and its extension cable, so the gap can be adjusted or the probe replaced without dismantling the machine.
Under the metric ordering code 32000-AA-BB-CC-DDD-EE-FF, this part number breaks down as follows:
- 00: no probe included
- 00: no probe cable included
- 04: 40 mm standoff adapter
- 470: 470 mm probe penetration
- 01: one M25 fitting and two plugs
- 02: 3/4-14 NPT mounting thread
The probe is ordered separately. The 3/4-14 NPT mounting thread is required when a standoff adapter is ordered.
Key Features
- Glass-reinforced PPS thermoplastic housing with conductive fibres for electrostatic dissipation
- AISI 304 stainless steel sleeve and retaining chain, with AISI 303 stainless steel outer sleeve and exterior screws
- CSA-certified Type 4X rating and IP66 rating
- External access for probe gapping and replacement without machine disassembly
- Seals differential pressure between the probe tip and the housing body when used with a 3300 XL 8 mm probe
- Housing impact strength certified by BASEEFA
Technical Specifications
| Parameter | Value |
|---|---|
| Part number | 32000-00-00-04-470-01-02 |
| Family | Bently Nevada 31000/32000 proximity probe housing (32000 = metric) |

| Probe penetration | 470 mm (option 470) |
| Fittings | One M25 fitting, two plugs (option 01) |
| Mounting thread | 3/4-14 NPT (option 02) |
| Temperature range | -51 to +105 deg C |
| Protection rating | Type 4X (CSA), IP66 |
| Housing material | Glass-reinforced PPS with conductive fibres |
| O-ring material | Neoprene |
| Recommended torque (retaining nut) | 29.4 N m (260 in lb) |
| Weight | 1.2 kg typical |
| Housing body size | 91.4 mm wide × 144.8 mm high × 76.2 mm deep |
| Probe sleeve | 12.7 mm diameter stainless steel |
| Sleeve adjustment range | ±13 mm (±0.5 in) |
| Unsupported length limit | Standoff + penetration above 305 mm needs extra sleeve support |
| Longest standoff + penetration by probe cable length | 394 mm for 0.5 m probe; 760 mm for 1.0 m probe |
| Probe seal / housing seal | Viton O-ring inside probe case; Neoprene O-ring between sleeve and housing |
| API compliance | API 670 for externally mounted probe housings |
The datasheet requires additional sleeve support near the probe when the standoff adapter length plus the probe penetration exceeds 305 mm, to prevent resonance. With 40 mm plus 470 mm, this configuration is above that limit. The housing is sealed against hose-directed water but is not designed to resist internal or external pressure.
Applications
- Radial vibration and Keyphasor probe mounting on steam and gas turbines, compressors and pumps
- Installations where the probe must pass through the machine casing to reach the shaft
- Replacement of damaged or corroded housings on rotating equipment in refineries, gas plants and power stations
Bently Nevada 32000 Ordering Code and Options
The metric housing is coded 32000-AA-BB-CC-DDD-EE-FF. In 32000-00-00-04-470-01-02, A = 00 means no probe is supplied and B = 00 means no probe cable. C = 04 is a 40 mm standoff adapter, the shortest offered; adapters run to 200 mm in 10 mm steps. D = 470 is a 470 mm probe penetration, within the 25 to 760 mm range ordered in 1 mm steps. E = 01 is one M25 fitting with two plugs, and F = 02 is a 3/4-14 NPT mounting thread, which is mandatory whenever a standoff adapter is ordered.
Standoff plus penetration here is 510 mm. That is beyond the 394 mm limit for a 0.5 m probe lead, so a probe with a 1.0 m lead (limit 760 mm) has to be used. It is also above 305 mm, where Bently Nevada requires additional sleeve support near the probe to avoid resonance; the listed accessory is probe support / oil seal 37948-01.
Probe choices the housing can be ordered with are 3300 XL 8 mm, 3300 XL NSv and 3300 XL 11 mm.
Bently Nevada 32000 Installation Notes
The datasheet sequence is: fit the outer sleeve into the machine case, insert the probe sleeve and set the gap, disconnect the probe cable and place the housing over the outer sleeve, slide the retainer under the retaining nut and tighten it, reconnect the cable and connector protector, then fit the cover and tighten the captive screws. All four holes in the housing base accept a sleeve, conduit fitting or cable gland; unused holes are closed with the supplied plugs. The housing gives mechanical and weather protection only and is not explosion-proof.
Why Seven Star LLC
Seven Star LLC supplies Bently Nevada transducer hardware to rotating equipment teams across Oman and the GCC. A housing cannot be shimmed to fit a different casing. Before quoting, we therefore check the complete part number, standoff length, probe penetration and mounting thread against your machine drawing or the existing housing.

About brand
Since 1961 Bently Nevada, of Minden, Nevada, USA, has been closely tied to two things: the eddy current proximity probe and the rack-based machinery protection system. The 3500 rack is found on turbines and compressors in most large process plants.
Seven Star LLC is an independent supplier of Bently Nevada 3500 monitor modules, interface and communication modules, proximity probes, accelerometers and velocity transducers for operators in Oman and the GCC, with every item matched to the full part number.
Bently Nevada 3500 modules and transducers
The listed 3500 modules include the 3500/20 Rack Interface Module, the 3500/50M Tachometer, the 3500/61 Temperature and 3500/62 Process Variable monitors, the 3500/64M Dynamic Pressure monitor, the 3500/44M for aeroderivative gas turbines and the 3500/46M Hydro monitor. Reciprocating compressor monitoring is covered by the 3500/70M, 3500/72M and 3500/77M. The 3500/92 Communication Gateway and 3500/94M display link the rack to the control system. Transducers include the 3300 XL proximity probe system, the 330400 accelerometer and the 190501 Velomitor CT velocity transducer. The manufacturer's newer platform, Orbit 60, is offered as the modernization path for 3500 racks, and System 1 software handles diagnostics.
Where Bently Nevada vibration monitoring is used
Steam and gas turbines, generators, centrifugal and reciprocating compressors, large pumps, hydro units and cooling tower fans in oil and gas, power generation, petrochemical and mining plants are the usual machines. Measurements include radial vibration, thrust position, speed, phase, differential expansion, bearing temperature, rod position and cylinder pressure.
Ordering Bently Nevada parts: what we need
Send the complete part number with every option field, for example 330103-00-05-10-01-00 for a probe or the 3500 module number with its option dashes, plus the matching I/O module number. For probe systems state probe series, system length and the hazardous area approval. A photo of the label avoids transcription errors, and for rack modules the firmware revision is useful.
