The 21504-012-032-10-02 is a Bently Nevada 7200 series 8mm proximity probe featuring a high-performance unarmored FEP triaxial cable. Fully compatible with 18745 Proximitor Sensors, this unit works seamlessly with legacy 3300 and 9000 monitoring systems to deliver accurate non-contact shaft vibration logging and stable long-term machinery displacement measurements.

High-Resolution Measurement

 Linear Range: Offers 80 mils (2 mm) of linear measuring range for precise displacement monitoring.

Scale Factor: Provides 200 mV/mil (8 V/mm) scale factor for high-resolution output.

Frequency Response: Capable of measuring both static (position) and dynamic (vibration) distances accurately.

Material Construction: Fiberglass probe body suitable for confined space installations.

Application Versatility: Ideal for shaft position and vibration measurements on rotating machinery.

Signal Integrity: Integral 1.0-meter cable with miniature coaxial connector ensures reliable signal transmission.
