Quick Detail

Description

The 21504-000-008-05-02 Standard Mount Probe is an 8 mm diameter industrial proximity sensor designed for precise position and vibration measurements in automated machinery. With an overall case length of 80 mm and a total length of 0.5 meters (20 in), it allows installation in confined spaces without affecting signal accuracy. The probe features a 3/8-24 UNF thread and Miniature male coaxial connector, enabling secure and reliable connections to Proximitor sensors. Operating with an input power of -17.5 Vdc to -26 Vdc and drawing a maximum of 12 mA, the 21504-000-008-05-02 Standard Mount Probe delivers a maximum linear range of 2.0 mm (80 mils) and an output calibrated range of 0.25 mm (10 mils) from the probe face, ensuring precise radial and axial measurement on shafts and flat targets. The probe is engineered for rapid integration into standard 3300 XL transducer systems and supports both static position and dynamic vibration monitoring in fluid-film bearing applications. Its short unthreaded tip length (0.0 mm) allows close-gap measurement in tight mounting areas, while the miniature connector simplifies field wiring.

Applications

Radial Shaft Position Measurement
The 21504-000-008-05-02 Standard Mount Probe measures radial displacement on shafts ≤ 50 mm diameter, using its 2.0 mm linear range to detect minute deviations in high-speed rotating machinery.

Axial (Thrust) Position Monitoring
With an output calibrated range of 0.25 mm, the probe provides precise axial clearance readings on fluid-film bearings, supporting predictive maintenance and machine alignment.

Dynamic Vibration Analysis
The probe captures vibrations in machinery at operational speeds while maintaining accuracy over its 0.5-meter cable length, enabling detailed vibration profiling in automated systems.

Keyphasor Signal Generation
Connected via its Miniature male coaxial connector, the probe delivers clean signals for Keyphasor timing and speed measurements, critical for process control and synchronization.

Specifications

Competitive Advantage

Compact Design for Tight Installations
The 8 mm diameter and 0.0 mm unthreaded tip allow installation in restricted spaces without reducing measurement accuracy.

High-Precision Output
The 2.0 mm linear range and 0.25 mm output calibrated range ensure precise radial and axial detection, suitable for small targets and high-speed machinery.

Low Power Consumption
Operating at -17.5 Vdc to -26 Vdc with 12 mA max, the probe minimizes power draw while maintaining signal integrity over long-term operation.

Reliable Connection
The Miniature male coaxial connector supports robust signal transmission and simplifies field wiring, reducing installation time and errors.

Integration with 3300 XL Systems
The probe’s standard configuration and 3/8-24 UNF thread allow seamless connection to existing 3300 XL transducer systems, enabling system upgrades without modifying mounts or sensors.
