The Bently Nevada 21504-000-020-10-02 / 21504-000-032-10-02 8 mm Standard Mount Probe is a high-precision non-contacting transducer designed for measuring both static and dynamic shaft movements. With a standard 3/8-24 thread, 8 mm diameter, and miniature male coaxial connector, it offers reliable installation and signal transmission in industrial machinery. The probe supports operation in environments with up to 95% non-condensing relative humidity and functions at -17.5 Vdc to -26 Vdc with a 12 mA maximum current, providing accurate data under a wide range of operating conditions.
Designed for comprehensive rotor monitoring, this probe system measures radial vibration, axial thrust position, shaft average radial position, vibration amplitude, phase angle, and eccentricity. With a frequency response from 0 Hz to 10 kHz, it is ideal for detecting bearing wear, rotor imbalance, misalignment, and rotor bow. Compatible with both 2.0 inch (020) and 3.2 inch (032) case lengths, and total length of 1.0 meter (39 inches), it integrates seamlessly into 7200 and 8 mm proximity transducer systems for machinery diagnostics and predictive maintenance.
