Description：

Bently Nevada 21000-00-00-15-226-03-02 Proximity Probe Housing Assembly is a robust proximity probe housing assembly that provides secure installation and reliable environmental protection for proximity probe systems used in industrial rotating machinery monitoring.

The physical configuration of this specific part number delivers an extra-long 22.6-inch (574 mm) probe penetration sleeve depth, a 1.5-inch (38 mm) standoff adapter, and a 3/4-14 NPT tapered pipe mounting thread for casing installation, complete with dedicated sealed conduit and cable gland fittings. Because the sleeve length exceeds 12 inches (304 mm), an additional sleeve support is strictly required to reduce the vibration associated with unsupported long sleeve lengths.

Frequently asked questions

Q1: What is the minimum standoff adapter length of the 21000-00-00-15-226-03-02 housing assembly?

A: The 21000-00-00-15-226-03-02 housing assembly is supplied with a 1.5-inch (38 mm) standoff adapter, which provides the minimum mounting length required for proper probe installation.

Q2: What does the 21000-00-00-15-226-03-02 Probe Penetration code "226" indicate?

A: Code 226 specifies a 22.6-inch probe penetration length, allowing the proximity probe to extend deep into the machine housing for accurate shaft vibration and position measurements.

Q3: What mounting thread is provided on this 21000-00-00-15-226-03-02 housing assembly?

A: The mounting thread is 3/4-14 NPT, a widely used tapered pipe thread standard suitable for industrial machinery and vibration monitoring applications.

Q4: Is the 3/4-14 NPT mounting thread compatible with standard industrial installations?

A: Yes. The 3/4-14 NPT thread is a standard industrial connection that provides secure mounting and reliable sealing in many machinery housing applications.

Product Applications
