  • Radial Vibration Monitoring: Mounted on the bearing housing, it measures the dynamic displacement of the shaft relative to the bearing, used to identify imbalance, misalignment, or oil film instability.
  • Axial Displacement Protection: Monitors the thrust position of the rotor to prevent collisions between the rotor and stators (such as impeller and casing).
  • Phase Reference (Keyphasor®): Measures shaft speed and provides a phase reference point for Bode plot and polar coordinate analysis.
  • Extreme Temperature: The probe and cable operate within a temperature range of -51°C to +177°C (-60°F to +351°F).
  • Pressure and Sealing: The probe head and housing are sealed to withstand pressure differentials up to 7 bar (100 psi).
  • Chemical Resistance: Utilizing a polyphenylene sulfide (PPS) tip and stainless steel housing, it resists corrosion from most industrial lubricants, solvents, and process chemicals.
  • System Composition: Requires connection to a 3300 XL extension cable and a 3300 XL proximitor. The proximitor converts displacement changes into a stable analog voltage signal (standard sensitivity 7.87 V/mm or 200 mV/mil).
  • Monitoring Rack: Signal input to a Bently Nevada 3500 or 2300 series monitoring system.
  • Protection Functions: The monitoring system automatically compares the collected data with preset Alert and Danger limits. If a threshold is exceeded, the system outputs a control command (shutdown interlock) via relay to prevent major equipment damage.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What space-saving advantage does the 21000-16-10-00-120-04-02 offer compared to standard housings?
The absence of a standoff adapter reduces overall assembly length, making it ideal for installations with limited clearance between machinery casing and surrounding equipment.
How does the 21000-16-10-00-120-04-02 maintain hazardous area compliance with only one NPT plug?
The single 3/4-14 NPT plug provides proper sealing for the cable entry point, maintaining the CSA explosion-proof integrity while simplifying installation with fewer components.
What types of machinery benefit most from the 2.0 inch probe penetration of this housing?
Centrifugal compressors, steam turbines, and pumps with thinner casing walls benefit from the 2.0 inch penetration, providing adequate probe depth without excess protrusion into the measurement area.
Why choose the 21000-16-10-00-120-04-02 over stainless steel alternatives for offshore applications?
The aluminum construction offers weight savings for top-side installations while maintaining CSA Type 4 corrosion resistance, though stainless steel is recommended for submerged or highly corrosive environments.
