The Bently Nevada 24701-28-10-00-140-04-01 accepts a 3300 XL 8mm proximity probe. The reverse mount design secures the probe from inside the housing. The maximum assembled length reaches 29.2 inches for deep installations.

Assembly Components and Structure

The 24701-28-10-00-140-04-01 consists of several key parts working together. A dome cover screws into the main body of the housing securely. Threaded ports allow conduit connections for electrical wiring. A probe sleeve of optional length holds the probe in position.

O-rings provide environmental sealing between mating surfaces. A reverse mount proximity probe sits inside the sleeve assembly. Thread seal material prevents leakage through the connection points. Optional conduit fittings can be added if needed for your installation.

The housing protects the probe from mechanical damage and contamination. The 303 stainless steel body resists corrosion in most industrial environments. The 304 stainless steel sleeve adds extra durability at the probe tip. This assembly simplifies installation by combining all necessary components.

Installation Guide for the 24701-28-10-00-140-04-01

Follow these steps to install the Bently Nevada 24701-28-10-00-140-04-01 correctly.

1. Drill and tap the mounting hole to match the housing threads.

2. Clean all mounting surfaces thoroughly before installation.

3. Insert the housing assembly into the prepared mounting hole.

4. Tighten the housing to the recommended torque value.

5. Connect the conduit to the threaded port on the housing.

6. Pull the probe cable through the conduit carefully.

7. Connect the probe cable to the proximitor or monitoring system.

8. Adjust the probe penetration to the 14 inch specified depth.

9. Secure the dome cover onto the housing body tightly.

10. Verify the air gap setting using a proximity probe test fixture.

Do not exceed the maximum (C)+(D) dimension of 29.2 inches. The visible probe marking helps confirm correct insertion depth. Use thread sealant on all NPT connections to prevent leakage. Protect the probe tip from damage during cable pulling operations.
