Product Overview

21000-28-05-15-039-03-02 is a configured Bently Nevada 21000 aluminum proximity probe housing assembly for externally mounting a proximity probe.

The complete assembly combines the aluminum housing and 304 stainless steel sleeve with a reverse-mount 3300 XL 8 mm probe. This order code specifies a 0.5 m probe cable, a 1.5 in standoff adapter, a 3.9 in probe penetration, E03 fitting hardware and a 3/4-14 NPT mounting thread.

The housing construction protects and supports the probe while its conduit ports and selected fittings provide the intended external cable entry arrangement.

Configuration

A - Probe with connector	28: 3300 XL 8 mm probe with selectable hazardous-area approvals
B - Probe cable length	05: 0.5 m (20 in)
C - Standoff adapter	15: 1.5 in (38 mm)

E - Fittings	03: NPT plug, NPT reducer and cable seal grip with grommets
F - Mounting thread	02: 3/4-14 NPT

Construction

Housing Aluminum body with a screw-in dome cover and threaded conduit ports.	Sleeve 304 stainless steel sleeve, 12.7 mm (0.50 in) diameter, configured by C and D dimensions.
Probe Reverse-mount 3300 XL 8 mm proximity probe with 0.5 m cable.	Sealing and entry O-rings, thread seal and E03 conduit-entry fitting hardware.

Installation

01 - Mounting interface
Use the specified 3/4-14 NPT mounting thread and the 1.5 in standoff adapter.

02 - Probe position
Set the 3.9 in probe penetration for the machine installation. The official adjustment range for option D is 13 mm (+/- 0.5 in).

03 - Cable and sleeve
Keep the probe lead longer than the sleeve and route the 0.5 m probe cable through the housing and selected cable seal grip.

04 - Support rule
Where C plus D exceeds 300 mm (12 in), the official datasheet requires sleeve support near the probe. This configured C plus D is 137 mm (5.4 in).

Environment

Probe temperature range	Operating and storage: -51 to +177 degrees C (-60 to +351 degrees F)
Probe approval selection	Option 28 specifies a 3300 XL 8 mm probe with selectable hazardous-area approvals
Housing designation	21000 aluminum housing
Explosion-proof note	Only CA versions of the housing are rated explosion-proof by CSA when ordered with the approved fitting options
Conduit entry	E03 fitting set with plug, reducer and cable seal grip
Reference standard	21000 and 24701 housings are described by the manufacturer as compliant with API 670 for externally mounted proximity probe housings

FAQ

Q1. How can a buyer verify the exact quoted model?

Match the complete code 21000-28-05-15-039-03-02 on the quotation, nameplate and package. Each suffix matters: 28 identifies the 3300 XL 8 mm probe, 05 the 0.5 m cable, 15 the 1.5 in standoff, 039 the 3.9 in penetration, 03 the fitting set and 02 the 3/4-14 NPT mounting thread.

Q2. How can New, Used or Refurbished condition be distinguished?

Request current photographs of the complete housing, dome cover, stainless steel sleeve, probe cable, connector, fittings and labels. A new unit should show no installation marks on the 3/4-14 NPT thread, no machine residue on the sleeve and no replacement or repair labeling.

Q3. How should supplier legitimacy and reliability be checked?

Verify the supplier legal entity, business address, payment beneficiary and traceable sales contact. Ask for a written offer that states Bently Nevada, the complete model 21000-28-05-15-039-03-02, condition, quantity and the exact order-code configuration.

Q4. Which specifications must an engineer confirm before purchase?

Confirm the 3300 XL 8 mm probe system, 0.5 m cable, 1.5 in standoff, 3.9 in penetration, 5.4 in combined C plus D dimension, E03 conduit fitting arrangement and 3/4-14 NPT mounting thread against the machine installation.

Q5. What physical evidence should be requested before payment?

Ask for date-marked photos of the full assembly, the complete part-number label, probe and connector, 12.7 mm stainless steel sleeve, E03 fittings and the 3/4-14 NPT mounting thread, plus a packing-list preview identifying 21000-28-05-15-039-03-02.

Q6. Can a similar 21000 suffix or another housing replace this model?

Not automatically. Changing any suffix can change probe type, cable length, standoff, penetration, fittings or mounting thread. A substitute should be accepted only after the engineer verifies every selected dimension and interface against 21000-28-05-15-039-03-02.
