Product Overview

The Bently Nevada 24701-16-10-00-083-03-02 is a complete proximity probe housing assembly. This unit protects a 3300 XL 8mm probe inside a rugged metal enclosure. The assembly works for permanent machine monitoring installations. Engineers use this model for turbines, compressors, and large rotating equipment. The 24701-16-10-00-083-03-02 simplifies installation by combining all required parts. You receive a pre-assembled housing with the probe installed.

Technical Specifications

Materials & Construction

The housing body uses 303 stainless steel for excellent corrosion resistance. The probe sleeve uses 304 stainless steel for added durability. A dome cover screws directly into the housing body. Threaded ports allow easy conduit connections. The assembly includes multiple O-rings for a tight seal. A thread seal prevents leakage at connection points.

Probe & Cable Details

This assembly contains a 3300 XL 8mm probe with connector. The probe cable length is 1.0 metre (39 inches). The cable is permanently attached to the probe. A connector sits at the cable end for easy monitor hookup. This model uses no standoff adapter (option -00). The probe penetration (C dimension) is 8.3 inches (083).

Dimensional Limits

The total visible probe length (C + D) with visible serial number reaches 17.0 inches (43.18 mm). The maximum total (C + D) dimension is 29.2 inches (74.2 mm). These dimensions help you verify proper probe position. Always measure your target distance before final mounting.

Fittings & Mounting

The fittings option (03) supplies a complete set of connection parts. You receive one 3/4-14 NPT plug. You also get one 3/4-14 to 1/2-14 NPT reducer. The package includes one cable seal grip with three interchangeable grommets. These grommets fit cable sizes:

• 1/8 to 3/16 inches

• 1/4 to 5/16 inches

• 5/16 to 3/8 inches

The mounting thread option (02) is 3/4-14 NPT. This thread is required when no standoff adapter is selected. It matches standard industrial conduit fittings.

Weight & Physical Data

The typical weight is 1.8 kg (4.1 lb) without fittings. With all fittings included, the weight stays near this value. The compact design fits tight machine spaces. The stainless steel body resists impact and vibration.

Installation Guide

Follow these steps to install the Bently Nevada 24701-16-10-00-083-03-02 correctly. First, select a mounting location near your target shaft. Ensure the probe tip clears the shaft by 1.27 mm (50 mils). Second, thread the housing into the machine case using the 3/4-14 NPT threads. Apply thread sealant to prevent leakage.

Third, adjust the probe penetration to the 8.3 inch setting. Verify the probe tip gap with a micrometer. Fourth, connect the conduit to one threaded port. Use the supplied reducer if your conduit is 1/2-14 NPT. Install the cable seal grip on the conduit end. Select the correct grommet for your cable diameter.

Fifth, route the probe cable through the seal grip. Tighten the grip to secure the cable. Connect the probe connector to your extension cable or monitor. Sixth, screw the dome cover onto the housing body. Hand-tighten only. Do not overtighten the dome cover.

Frequently Asked Questions (FAQ)

1. What is the maximum probe penetration of the 24701-16-10-00-083-03-02?
The maximum penetration (C+D) is 29.2 inches (74.2 mm). The visible probe length with serial number is 17.0 inches maximum. Do not extend beyond this limit.

2. Can I use the Bently Nevada 24701-16-10-00-083-03-02 with a 3300 XL monitor?
Yes, the 24701-16-10-00-083-03-02 contains a 3300 XL 8mm probe. This probe matches 3300 XL proximitor and monitor systems perfectly. The 1.0m cable works within the total 305m field wiring limit.

3. What conduit sizes fit the 24701-16-10-00-083-03-02 housing ports?
The ports accept 3/4-14 NPT directly. Use the included reducer for 1/2-14 NPT connections. The cable seal grip accepts cables from 1/8 inch to 3/8 inch diameter.

4. Does this housing resist harsh industrial environments?
Yes, the 303 and 304 stainless steel construction provides excellent corrosion resistance. The O-rings and thread seal prevent moisture ingress. This assembly works in dirty or wet machine areas.

5. How do I replace the probe inside the 24701-16-10-00-083-03-02?
First, remove the dome cover. Disconnect the probe cable from your system. Unscrew the probe sleeve locknut. Slide the old probe out. Insert the new 3300 XL 8mm probe. Retighten the locknut to 39.3 N·m. Reconnect the cable and replace the dome cover.
