Description

21504-00-08-05-02: 7200 series 8 mm standard mount proximity probe, featuring 0.0 in (Option 00) unthreaded length, 0.8 in (Option 08) case length, 0.5 m (Option 05) total cable length, and a miniature male coaxial connector (Option 02). This transducer is part of the 7200 5 mm and 8 mm proximity transducer system, which utilizes the eddy current principle to provide non-contacting displacement measurement between the probe tip and the observed machine surface. The system is designed for shaft vibration and axial position monitoring on critical rotating machinery, including gas turbines, steam turbines, compressors, and pumps. This 8 mm probe configuration is constructed of polyphenylene sulfide (PPS), a plastic capable of withstanding harsh, wet, or chemically active environments. It provides a linear measuring range of 80 mils (2 mm) with a scale factor of 200 mV/mil (7.87 V/mm). Probes are compatible with 7200 series Proximitor sensors and extension cables to complete the transducer loop.

Features

8 mm diameter tip construction
Polyphenylene sulfide (PPS) probe body for chemical resistance
Standard mount configuration with 3/8-24 threads
Option 00: 0.0 in unthreaded length
Option 08: 0.8 in case length
Option 05: 0.5 m integral cable
Option 02: Miniature male coaxial connector
