Installation Guide

Follow these steps to install the Bently Nevada 24701-16-05-00-073-04-02 correctly. First, mount the housing using the 3/4-14 NPT thread option directly to your machine. Second, install the single 3/4-14 NPT plug into the unused conduit port. Third, run the probe cable through the remaining conduit port to your monitoring system. Fourth, verify the probe penetration reaches exactly 7.3 inches to the target. Fifth, screw the dome cover onto the housing body after checking the probe gap. Finally, tighten all connections to prevent moisture entry.

Frequently Asked Questions (FAQ)

Q1: How is the Bently Nevada 24701-16-05-00-073-04-02 different from the -03 fitting option?
A: This -04 option includes only one 3/4-14 NPT plug. The -03 option adds a reducer and a cable seal grip with three grommets. Choose -04 for simple conduit connections without cable sealing needs.

Q2: Can I add a standoff adapter to this housing later?
A: Yes, you can add a standoff adapter separately. This model uses -00 which means no standoff adapter is pre-installed. You will need to order the adapter as a spare part and modify the mounting thread accordingly.

Q3: What is the probe penetration depth for the Bently Nevada 24701-16-05-00-073-04-02?
A: The probe penetration is exactly 7.3 inches (073 suffix code). This shallow depth works well for machines with limited internal clearance. The total (C)+(D) dimension still reaches 13.5 inches maximum.

Q4: Does this housing protect the probe serial number from visibility?
A: Yes. The probe part number and serial number remain not visible after full assembly. This feature prevents unauthorized reading of probe identification during normal operation.

Q5: What materials resist wear in this probe housing assembly?
A: The body uses 303 stainless steel for machinability and strength. The sleeve uses 304 stainless steel for better weldability and corrosion resistance. Both materials provide long service life in industrial environments.
