Overview Manuals Specifications Applications Protection Functions Installation and Upgrades

Features:

  • 8 mm probe diameter with 3/8-24 UNF threads and extended case length provides standard English mounting compatibility with deeper reach for thicker machine casings.
  • PPS (polyphenylene sulfide) tip material with thicker coil encapsulation offers excellent chemical resistance and superior durability against physical abuse compared to 5 mm alternatives.
  • Integral cable design with custom length configuration simplifies installation by eliminating the need for separate extension cables in many applications.
The 21504-32-56-10-02 is designed for installations where the measurement target sits deeper inside the machine casing than standard probes can reach. Its extended case length allows the probe to pass through thicker turbine casings, heavy compressor walls, or multiple insulation layers without requiring standoffs or custom mounting hardware.

The 21504-32-56-10-02 is constructed with a PPS (polyphenylene sulfide) probe tip, a material chosen for its exceptional resistance to a wide range of industrial chemicals. This makes the probe particularly suitable for applications where exposure to lubricating oils, hydraulic fluids, solvents, or corrosive agents is routine—common in process compressors, chemical plants, and offshore facilities.

The 21504-32-56-10-02 features an integral cable designed to match specific installation requirements, eliminating the need for a separate extension cable in many applications. This reduces the number of connections and potential failure points in the monitoring path, while simplifying parts management.

The 21504-32-56-10-02 Bently Nevada Mount Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Condition New Original ready stock
  • Product Family 21504-32-56-05-02,21504-32-56-15-02,21504-32-56-10-00

  • Radial Vibration Monitoring: Measures dynamic oscillations within journal bearings to determine imbalances or misalignments.
  • Axial Displacement Monitoring: Monitors the condition of thrust bearings to prevent mechanical collisions between the rotor and stator.
  • Speed ​​and Phase Measurement: Provides synchronization signals as a keyphasor sensor.
  • Typical Equipment: Steam turbines, compressors, industrial fans, pumps, generators, and centrifuges.
  • Gap Voltage Monitoring: Ensures the probe is centered in the linear range by measuring the gap voltage (typically set between -9V and -11V DC).
  • OK Circuit Diagnosis: The system automatically detects open or short circuits in the cable. If the signal is out of range (e.g., greater than -17.5Vdc or less than -2Vdc), a "Not OK" signal is triggered to prevent erroneous protection actions due to sensor failure.
  • Environmental Resistance: Possesses excellent chemical resistance, withstanding corrosion from 10% sulfuric acid and MEK solvent, and operates stably at extreme temperatures ranging from -34°C to +177°C.
  • Installation Requirements: Use 3/8-24 UNF standard threads for installation. Strictly adhere to the linear range specified in API 670 (approximately 2.0 mm / 80 mils) during installation.
  • Full Interchangeability: The 7200 series system (probe, extension cable, preamplifier) ​​is fully interchangeable; no on-site recalibration is required when replacing components.
  • 3300 XL Upgrade: While the 7200 series offers excellent performance, Bently Nevada's current flagship product is the 3300 XL series. These two series are generally interchangeable, but it is strongly recommended to avoid mixing components from different brands (i.e., the so-called "Frankenstein System") to prevent reading errors.
