Application Industry

External bearing-housing instrumentationSupports an externally mounted reverse-mount proximity probe with a standoff between the enclosure and machine casing.

Intrinsically safe measurement installationsApproved probes can be ordered for intrinsically safe applications; verify the complete probe and system approvals for the installation.

Shaft position measurementSupports external probe mounting for position sensing in a configured 8 mm transducer system.

Speed and phase-reference instrumentationProvides mechanical mounting and cable-entry protection for engineered speed or Keyphasor measurement points.

FAQ

Which probe and cable are selected by 21000-28-05-15-039-03-02?

The order options select an 8 mm probe with a 0.5 m cable. Confirm the probe approval marking and the matching extension cable and sensor before commissioning.

What mechanical lengths define 21000-28-05-15-039-03-02?

The standoff is 1.5 inches and the nominal penetration is 3.9 inches. Check both dimensions against the casing and target position.

How is 21000-28-05-15-039-03-02 attached to the machine?

The specified mounting thread is 3/4-14 NPT. Verify thread engagement and the selected standoff arrangement before installation.

Does 21000-28-05-15-039-03-02 automatically provide an explosion-proof installation?

No. Housing version, fittings, probe approvals and the complete installation must be assessed together. An approved probe selection alone does not establish an explosion-proof assembly.

When does 21000-28-05-15-039-03-02 need additional sleeve support?

The manufacturer requires added support near the probe when the combined standoff and penetration dimension exceeds approximately 12 inches. The specified nominal dimensions are below that threshold.
