Probe Housing 21000-16-10-15-070-03-02 - Bently Nevada

Product Overview

The Bently Nevada 21000-16-10-15-070-03-02 is a robust, explosion-proof proximity probe housing designed for mid-range penetration applications. This assembly serves as a critical interface for 8mm eddy current sensors, providing reliable vibration and position monitoring for industrial pumps and compressors. Featuring a 1.5-inch standoff adapter and a 7-inch penetration depth, it allows for high-precision measurement in hazardous environments while facilitating probe maintenance without machine downtime.

Technical Specifications

Installation & Maintenance

1. Adapter Mounting: Secure the 1.5-inch standoff to the machine case to ensure proper alignment and mechanical clearance for the 7-inch penetration depth.

2. Gap Voltage Setting: Connect the probe to a 3300 XL Proximitor and adjust the gap until the output voltage reaches -10.0 Vdc. This represents the optimal center-point for measurement accuracy.

3. Conduit Sealing: Use the provided 3/4-14 NPT fittings and grommets to ensure an explosion-proof seal, protecting the internal connections from moisture and gas ingress.

Engineering Advantages

The Bently Nevada 21000 series is globally recognized for its resilience in chemical plants and water treatment facilities. The 304 stainless steel sleeve components resist corrosion from process gases, while the housing assembly effectively dampens external noise. This configuration is optimized for mid-sized machinery where standard probes cannot reach the shaft or where additional external standoff is required for casing clearance.

Technical FAQs

Q1: What is the benefit of the 1.5-inch standoff?
A1: The standoff allows for the use of shorter probes or provides necessary clearance for insulation and external machine components while maintaining the 7-inch penetration depth.

Q2: Can this assembly monitor radial vibration and axial thrust?
A2: Yes, when paired with the appropriate 3300 XL Proximitor, this 8mm probe housing is ideal for both radial vibration and axial position measurements.

Q3: Is the internal probe replaceable?
A3: Absolutely. The design of the 21000-16-10-15-070-03-02 allows the internal probe to be removed for inspection or replacement without dismounting the entire housing from the machine.
