Information
- 21000-27-05-00-40-03-02 is a 21000 externally mounted housing assembly configured with a 3300 XL NSv probe with selectable hazardous-area approval option, 0.5 m (20 in) cable and 3/4-14 NPT mounting thread.
Cable 05: 0.5 m (20 in); standoff 00: No standoff adapter
Penetration 40: 4.0 in (option 40 as supplied; confirm 040 against the three-digit source format); fittings 03
Standoff option 00 specifies no standoff adapter. Penetration option 40 identifies 4.0 in (option 40 as supplied; confirm 040 against the three-digit source format). Check shaft target, bracket geometry, sleeve support and adjustment travel against the site drawing before installation.
Fitting option 03 specifies one 3/4-14 npt plug, one 3/4-14 to 1/2-14 npt reducer, and one cable seal grip with grommets; mounting option 02 is 3/4-14 NPT. Confirm the offered hardware and site enclosure/approval requirements rather than relying on a family name.

Apter Power field guide - PDF, 3 pages. 21000 probe selection, D40 label check, fitting package and handover.
Installation context: Use the externally mounted housing only with an approved shaft target, machine-case mounting and matched Bently Nevada probe measurement chain.
-
Shaft vibration probe mounting
Mount the specified probe at the approved shaft target and match the monitor input to the installed measurement chain. -
Axial position interface
Check penetration and shaft travel against the mechanical drawing before setting the reference gap. -
Accessible maintenance
Use the external housing to inspect or replace a probe while following site isolation and sealing procedures. -
Configured replacement
Compare all six code groups, site fittings and supplied components with the removed assembly.
The base housing number alone does not fix probe family, cable length, penetration or fittings.
The supplied D field uses 40. The original source presents DDD as a three-digit field; check the physical label before accepting 040 as equivalent.
Record the 0.5 m (20 in) probe cable and verify the companion Proximitor Sensor configuration.
Option 03 specifies one 3/4-14 npt plug, one 3/4-14 to 1/2-14 npt reducer, and one cable seal grip with grommets; compare actual supplied hardware.
Mounting option 02 is 3/4-14 NPT; check machine-case threads and sealing.
After controlled installation, document target gap, cable route and monitor response.
