Compare two 1.0 metre 7200 Series standard-mount proximity probes and select the case length that matches the installed machine geometry.
Product Description
Standard-Mount Probes for a Matched 7200 System
Bently Nevada 21504-000-020-10-02 and 21504-000-032-10-02 are standard-mount proximity probes from the 7200 Series 5 mm/8 mm Proximity Transducer System. The system is a noncontacting, gap-to-voltage arrangement used to measure static and dynamic distance between the probe tip and a conductive target.
Each probe operates with a compatible extension cable and 7200 Series Proximitor Sensor. This complete measurement chain supports machinery vibration and position monitoring while keeping the sensing element clear of the moving shaft.
Both configurations use the same unthreaded length, total length and connector option. The decisive selection point is the overall case length required by the installed mounting geometry.

Measurement Uses
Typical 7200 Proximity-System Applications
Measures dynamic shaft movement relative to the probe mounting position.
Tracks static rotor or shaft position against a suitable conductive target.
Supplies a displacement signal to a compatible monitoring and protection system.
Supports vibration and position trending on rotating and reciprocating machinery.
Lifecycle & Replacement
Treat Migration as a Complete Transducer-System Change
LEGACY 7200 SERIES
21504 Standard-Mount Probes
The current Bently Nevada proximity-sensor portfolio centers on newer transducer families. The manufacturer publications reviewed for these complete 21504 numbers do not state a model-specific discontinuation date, last-time-buy date or support-end date.
Replacement engineering checks
Mechanical fitThread, case length, unthreaded length, probe-tip position and connector clearance.
Electrical chainProbe, extension cable, Proximitor Sensor and total electrical length.
Signal compatibilityScale factor, output curve, target material and monitor configuration.
Site requirementsHazardous-area approvals, barriers, grounding and environmental conditions.
3300 XL 5 mm/8 mm is the newer migration family, but neither model above should be replaced by changing only the probe. A conversion can require the matching extension cable and Proximitor Sensor, mechanical verification, monitor review and commissioning checks.

Buyer Questions
Frequently Asked Questions
What separates 21504-000-020-10-02 from 21504-000-032-10-02?
Overall case length is the ordering difference: 2.0 inches for 21504-000-020-10-02 and 3.2 inches for 21504-000-032-10-02. Both have 0.0-inch unthreaded length, 1.0 m total length and a miniature male coaxial connector.
Which system components work with these 21504 probes?
Each probe operates as part of a matched 7200 Series 5 mm/8 mm transducer system with the appropriate extension cable and Proximitor Sensor.
How should a buyer choose between the two case lengths?
Match the installed probe part number and verify available mounting depth, thread engagement, probe-tip position, connector clearance and cable routing before ordering.
When were these two 21504 configurations discontinued?
The manufacturer publications reviewed for this page do not state a model-specific discontinuation date, last-time-buy date or support-end date for either complete part number.
Can a 3300 XL probe replace either 21504 model directly?
A one-for-one replacement should not be assumed. Migration requires verification of the complete probe, extension cable and Proximitor Sensor chain together with mechanical fit, electrical length, monitor configuration, target material and approvals.
