24701-00-00-00-290-03-02 is a Bently Nevada 24701 stainless-steel probe housing ordered without a probe, probe cable or standoff adapter. It includes a 29.0-inch probe-penetration sleeve, the E03 plug/reducer/cable-seal package and a 3/4-14 NPT mounting thread.

The 24701 uses a 303 stainless-steel body and 304 stainless-steel sleeve. Because the sleeve is longer than 12 inches, the installation requires additional support near the eventual probe location to control resonance.

• Provides a corrosion-resistant external enclosure and sleeve for a separately selected reverse-mount probe.
• Offers a cable-seal transition through the reducer and supplied grommet sizes.
• Allows the probe and cable to be chosen independently for the exact measurement loop.
• Supports API 670 externally mounted housing practice.
• Provides CSA Type 4 enclosure protection when the complete assembly is installed as documented.

• Select the reverse-mount probe family, cable length, connector and approvals separately.
• Engineer sleeve support near the target before installing the 29-inch assembly.
• Choose the cable-seal grommet that matches the actual cable diameter and verify strain relief.
• Confirm the 3/4-14 NPT machine port and external cover/service clearance.
• Gap and test the completed transducer loop only after all separately ordered parts are installed.

• External probe mounting where stainless-steel housing construction is required.
• Long-reach turbine or compressor measurement points with engineered sleeve support.
• Retrofit assemblies where the probe and cable are supplied or retained separately.
