The BENTLY NEVADA 21504-000-008-10-02 is configured as an 8 mm standard mount probe with a 3/8-24 UNF threaded body. The ordering code specifies 0.0-inch unthreaded length, 0.8-inch overall case length, a 1.0-meter integral cable, and a miniature male coaxial connector. This compact configuration is suitable for installations where limited mounting space is available.
The BENTLY NEVADA 21504-000-008-10-02 provides a calibrated 80 mil (2.0 mm) linear measurement range beginning approximately 10 mils (0.25 mm) from the probe face. When installed with a compatible 7200 Series Proximitor Sensor, the transducer system delivers accurate non-contact measurements for shaft vibration, shaft position, thrust position, and rotor eccentricity.
The BENTLY NEVADA 21504-000-008-10-02 operates from a supply voltage of -17.5 to -26 VDC with a maximum current consumption of 12 mA. The probe utilizes eddy current sensing technology, eliminating physical contact with rotating components and providing reliable long-term performance in demanding industrial environments.

Features:
- Frequency Response: 0 Hz (DC) to 10 kHz
- Noncontacting
- Gap-to-Voltage Transducer Systems
- Measures Static and Dynamic Distances
The Bently Nevada 7200 5mm / 8mm Series Proximity Transducer Systems are noncontacting, gap-to-voltage transducer systems that measure static as well as dynamic distances between the probe tip and the observed target. The general application in any requirement for an accurate, noncontacting displacement measurement. However, the most common use is for shaft position and vibration measurements on rotating and reciprocation machinery. They are designed for use with virtually any machine type including gas and steam turbines, compressors, pumps, centrifuges, electric motors and generators. The system offer 80 mils (2mm) of linear measuring range and are compatible with API 670 requirements.
The 21504-000-008-10-02 Bently Nevada 5 mm and 8mm Standard Mount Probe may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 21504-000-008-10-02 probe features a frequency response of 0 to 10 kHz (0 to 600,000 cpm), making it suitable for radial vibration, axial thrust position, shaft average radial position, vibration amplitude and phase angle, and eccentricity measurements. Environmental limits for the 21504-000-008-10-02 probe and extension cable range from –30°F to +350°F (–34°C to +177°C), with the Proximitor rated from –60°F to +212°F (–51°C to +100°C). For 8 mm probes like the 21504-000-008-10-02, operation is not affected by direct contact with air, water, lube oil, ammonium hydroxide, sulfuric acid (10%), MEK, or DMF.
The 21504-000-008-10-02 is compatible with 3300 and 9000 Monitoring Systems, and the full 7200 transducer system is CSA, BASEEFA, and FM certified for use in specific hazardous locations. The complete system—consisting of the 21504-000-008-10-02 probe with integral coaxial cable, an extension cable, and a Proximitor—is designed to achieve a system length of either five or nine metres from probe tip to Proximitor. With its robust PPS construction, wide temperature range, and chemical resistance, the 21504-000-008-10-02 is a reliable and durable solution for critical machinery condition monitoring applications.

Thread Engagement: Screw the 8mm standard mount probe into the machine mounting hole, making sure to engage at least 5 full threads safely.
Target Distance: Set the initial mechanical gap using a multitester or voltmeter to achieve the correct initial gap voltage (typically -10 VDC nominal output for a standard 7200 series system).
Torque Control: Tighten the locknut carefully to standard pipe or straight-thread torque limits to prevent shifting during high machine vibration.
Environmental Protection: Route the probe body through a proper seal grip or housing assembly to block oil, moisture, and dust ingress
