Bently Nevada 21000-28-10-00-217-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-28-10-00-217-04-02 are listed below for quick reference:

Application Versatility in Rotating Machinery

The 21.7-inch probe penetration allows deep insertion into machine casings, while the 3/4-14 NPT thread ensures a secure, leak-proof seal. The CSA Type 4 enclosure rating means it withstands water splashes and dust ingress, making it suitable for outdoor or washdown areas.

Installation and Setup Guidance

When installing the 21000-28-10-00-217-04-02, ensure the mounting surface is clean and flat. Apply anti-seize compound to the 3/4-14 NPT threads to prevent galling in stainless steel. Tighten the fitting to the manufacturer's recommended torque, but avoid over-tightening which could distort the sleeve. The probe cable length of 1.0 m (39 inches) should be routed away from high-voltage lines and sharp edges.

Maintenance and Reliability

Periodically inspect the housing for signs of corrosion or physical damage, especially in chemically aggressive environments. Verify that the probe tip is clean and free of debris. The 304 stainless steel sleeve provides resistance to oxidation and mild acids, but regular visual checks ensure early detection of any issues.

Robust Construction for Demanding Environments

The Bently Nevada 21000-28-10-00-217-04-02 proximity probe housing assembly is engineered to protect critical vibration monitoring sensors in the harshest industrial settings. Its aluminum body with a 304 stainless steel sleeve provides corrosion resistance and mechanical strength, ensuring long-term reliability in applications such as turbines, compressors, and pumps.

Selection Guide and Purchasing Advice

When selecting this assembly, confirm that the probe penetration and thread type match your machine's requirements. The -04 fitting option includes one 3/4-14 NPT plug only; if additional fittings are needed, order separately. For availability and lifecycle status, please verify with AutoDCSTech before ordering.
