Features:
- 8 mm probe diameter with 3/8-24 UNF threads provides standard English mounting compatibility and the enhanced durability of larger tip construction.
- PPS (polyphenylene sulfide) tip material offers excellent chemical resistance to oils, solvents, and corrosive agents common in industrial environments.t
- Integral cable design with 1.0 meter length simplifies installation by eliminating the need for a separate extension cable in many applications.
The 21504-00-08-10-02 leverages the inherent durability advantages of the 8 mm platform, featuring thicker encapsulation of the probe coil in molded PPS plastic than 5 mm alternatives. This design choice significantly improves resistance to physical abuse, making the probe well-suited for machinery where accidental contact during installation or maintenance is a concern.
The 21504-00-08-10-02 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 21504-00-08-10-02 features a 1.0-meter integral cable, eliminating the need for a separate extension cable in many standard installations. This design reduces the number of connections in the monitoring path, which in turn reduces potential failure points and simplifies parts management. The cable is terminated with a gold-plated ClickLoc connector that locks securely with finger-tight torque, requiring no special tools for installation.
The 21504-00-08-10-02 Bently Nevada Proximity Probe may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Critical Machinery Monitoring: Widely used in steam turbines, large compressors, centrifugal pumps, and generators to mount probes for measuring axial vibration, axial displacement, or speed (keyphasor).
- Online Maintenance and Calibration: This housing is an essential component when internal space is limited, or when it is necessary to adjust the probe gap or replace the probe without removing the machine cover/stopping the machine.
- API 670 Compliance: Designed to comply with American Petroleum Institute (API 670) standards, suitable for critical equipment protection in the global oil, gas, and power industries.
- Physical Protection: The main housing is typically made of aluminum or stainless steel, providing excellent sealing (NEMA 4X or IP66 rating) to prevent the ingress of oil, water, dust, and corrosive chemicals.
- Hazardous Areas: Depending on the model suffix (e.g., option 02), this assembly is CSA/NRTL/C explosion-proof certified and can be safely installed in flammable and explosive environments such as Class I, Division 2, or Zone 2.
- Structural Strength: The housing can withstand the strong vibrations generated during mechanical operation, protecting the internal probes and connectors from physical damage.
- Probe Adjustment (Control): Through the adjustment mechanism on the housing, technicians can use a multimeter to monitor the preamplifier output voltage while the machine is running and precisely rotate the probe to set the DC bias voltage (typically -10 VDC) to achieve the optimal linear measurement point.
- Signal Monitoring: The probe inside the housing converts mechanical vibration or displacement into analog voltage signals and transmits them to the 3500 monitoring system via coaxial cable.
- The monitoring system continuously analyzes the signal. If the vibration exceeds the preset "Alert" or "Danger" threshold, it will automatically execute an alarm or trip protection procedure.
