21000-11-05-00-085-03-02
External Proximity Probe Housing Assembly
The Bently Nevada 21000 family provides an external housing arrangement for proximity-probe installations on rotating machinery. The assembly combines a protective metal housing, threaded conduit access, a probe sleeve, sealing elements and a reverse-mounted proximity probe arrangement. This configuration is associated with the 21000 aluminum housing family and is intended for installations where the probe must be positioned through a machine case while maintaining practical access for installation, adjustment and maintenance. |
CONFIGURATION
|
| Designed around the practical demands of externally mounted proximity measurement. | Aluminum housing · 304 stainless steel sleeve |
|
External Probe Protection
The housing places the proximity probe inside a dedicated metal enclosure, helping protect the sensing assembly while providing a defined path through the machine case. Threaded Conduit Access
Threaded ports accommodate conduit and sealing arrangements. The selected fitting configuration provides a practical route for cable protection and enclosure sealing. |
Installation Flexibility
The 21000 design supports different probe penetration and standoff arrangements within the product family. This allows the housing configuration to be matched to the geometry of the machine casing. Long-sleeve consideration
When the combined probe penetration exceeds 300 mm (12 in), additional sleeve support is required to reduce the possibility of resonance in an unsupported long sleeve. |

Mechanical & Environmental Characteristics
|
Installation Considerations
|
|
21000
Aluminum external proximity probe housing assembly with selectable probe, cable, standoff, penetration, fitting and mounting configurations. |
24701
Stainless-steel housing family using the same general external probe-housing concept for installations requiring a stainless housing body. |
164818
Compact proximity probe housing arrangement intended for applications where installation space is more restricted. |
31000 / 32000
Newer housing families offer more flexible mounting options and improved environmental resistance where an explosion-proof housing is not required. |
|
04 / FIELD USE
Application Logic
The 21000 housing concept is intended for machinery locations where a proximity probe must be installed externally through the machine casing. Its mechanical arrangement helps maintain the probe position while providing a protected path for the probe cable. It is particularly suited to condition-monitoring installations associated with rotating machinery where shaft displacement, radial vibration or axial position measurements are part of the protection strategy. |
|
|
Unexpected Measurement Drift
Check probe positioning, penetration, gap condition and mechanical integrity when the monitoring signal changes unexpectedly. |
Cable or Seal Damage
Inspect the cable route, seal grip and conduit interface when the installation shows signs of physical deterioration or moisture ingress. |
Mechanical Resonance Risk
Long unsupported sleeves can introduce vibration. When total C + D penetration exceeds 300 mm, additional sleeve support is required. |
|
PURCHASING SUPPORT
Make the Replacement Match the Machine
For a quotation, please provide the exact part number together with the installation requirements. This is especially important for 21000 assemblies because the configuration code determines probe arrangement, cable length, standoff, penetration, fittings and mounting interface. |

Can 21000-11-05-00-085-03-02 be treated as a direct mechanical replacement for another 21000 assembly?
Not automatically. The complete configuration should be matched, particularly probe selection, cable length, penetration, fittings and mounting thread. A housing with a different D or F configuration may require changes to the machine installation. |
Why does the 085 configuration of 21000-11-05-00-085-03-02 matter during replacement?
The 085 designation specifies an 8.5-inch probe penetration configuration. Changing penetration can alter the probe's physical relationship with the machine casing and target, so the installed geometry must be checked before substitution. |
|
What installation issue should be considered with the 21000-11-05-00-085-03-02 sleeve length?
If the combined standoff and penetration dimension exceeds 300 mm (12 inches), the sleeve requires additional support to reduce resonance caused by an unsupported long sleeve. |
How should 21000-11-05-00-085-03-02 be matched with the field cable arrangement?
The 05 field represents a 0.5 m probe cable length, while the 03 fitting configuration includes a plug, a 3/4-14 to 1/2-14 NPT reducer and a cable seal grip. The physical cable route should therefore be checked before ordering. |
|
What makes the 21000-11-05-00-085-03-02 suitable for critical machinery monitoring installations?
Its purpose is not to perform the monitoring calculation itself; it provides the mechanical environment for an externally mounted proximity probe. The aluminum housing and stainless-steel sleeve establish a protected, repeatable mounting arrangement for proximity measurement hardware used around rotating machinery. |

The 3500/22M 138607-01 Transient Data Interface (TDI) is the interface between the 3500 monitoring system and compatible software (System 1 Condition Monitoring and Diagnostic software and 3500 System Configuration software). The TDI combines the function of a 3500/20 Rack Interface Module (RIM) with the data collection capability of a communication processor such as TDXnet.
3500/22M is a Transient Data Interface Module manufactured and designed by Bently Nevada as part of the 3500 Series used for monitoring seismic activity.

The 3500/33 16-Channel Relay Module is a full-height module that provides 16 relay outputs. You can place any number of 16-channel relay modules in any of the slots to the right of the Transient Data Interface (TDI) Module. Each output of the 3500/33 16-Channel Relay Module can be independently programmed to perform voting logic.
The 3500/60 & 61 modules provide six channels of temperature monitoring and accept both Resistance Temperature Detector (RTD) and Thermocouple (TC) temperature inputs. The modules condition these inputs and compare them against user-programmable alarm setpoints. The 3500/60 and 3500/61 provide identical functionality except that the 3500/61 provides recorder outputs for each of its six channels while the 3500/60 does not.

The 3500/72M Recip Rod Position Monitor meets API 618 requirements for reciprocating compressors. It measures: l Rod position l Rod drop l Hyper-compressor The four-channel 3500/72M Recip Rod Position Monitor accepts input from proximity transducers, conditions the signal to provide dynamic and static position measurements, and compares the conditioned signals with userprogrammable alarms. Each channel, depending on how you configure it, typically conditions its input signal to generate various parameters called measured values.
The 3500/62 Process Variable Monitor is a 6-channel monitor for processing machine critical parameters that merit continuous monitoring, such as pressures, flows, temperatures, and levels. The monitor accepts +4 to +20 mA current inputs or any proportional voltage inputs between -10 Vdc and +10 Vdc. It conditions these signals and compares the conditioned signals to user-programmable alarm setpoints.
