01

Product Identity

Bently Nevada 21508-02-12-10-02 is a legacy 7200 Series 8 mm reverse-mount proximity probe. The documented configuration uses a 3/8-24 case without armor and a 1.0 m total lead.

Reverse-mount geometry affects how the probe is installed and accessed inside the machine or bracket. A correct spare must therefore match the mounting direction, thread, usable case geometry, lead and the associated 7200 extension cable and Proximitor sensor.

02

Three Decisions Before Ordering

Mounting direction

Confirm that the installed bracket calls for a reverse-mount probe and allows access for adjustment and locking.

Mechanical geometry

Match the 3/8-24 case and installed insertion arrangement rather than relying on an 8 mm family description alone.

Electrical chain

Retain the supported 7200 extension cable, Proximitor family and intended total system length.

03

Installation & Commissioning Guardrails

Before replacement

Record insertion depth, gap reference, locknut position and full labels from the probe and signal-chain components.

During installation

Protect the unarmored lead, respect the route and avoid loading the connector or cable at the mounting point.

After installation

Confirm the channel response using the plant procedure and assess a poor reading across the complete loop.

06

Maintenance Buyer Questions

Can 21508-02-12-10-02 replace a standard front-mount 8 mm probe?

Not as a general substitution. Reverse-mount geometry changes installation access and bracket fit, so the existing mounting arrangement must be compared first.

What mechanical details should be checked before installing 21508-02-12-10-02?

Confirm the 3/8-24 thread, insertion direction, usable case geometry, locknut arrangement and clearance around the unarmored lead.

Can 21508-02-12-10-02 be connected to any Bently Nevada extension cable?

No. The cable and Proximitor sensor should belong to the supported 7200 chain and preserve the intended total electrical length.

How should the unarmored lead on 21508-02-12-10-02 be routed?

Use a protected route that avoids abrasion, sharp bends, connector strain and contact with moving or hot surfaces according to the plant practice.

What should be checked if the signal changes after fitting 21508-02-12-10-02?

Review the installed gap, mechanical stability, connectors, extension cable and Proximitor sensor as a complete channel before assigning the cause.

What should a buyer provide for a 21508-02-12-10-02 quotation?

Provide the full probe label, mounting photo, insertion details, cable and Proximitor labels, quantity, delivery country and outage date.
