Applications
-
Steam Turbines: The Bently Nevada 330709-000-040-50-01-05 monitors shaft vibration and radial position, preventing unplanned downtime.
-
Centrifugal Compressors: With a 5.0 meter cable and wide temperature range, this probe suits high-speed rotating equipment.
-
Pumps and Generators: The probe's cross-talk limitation ensures accurate readings even in close-quarter installations.
Installation & Setup
Install the Bently Nevada 330709-000-040-50-01-05 in a tapped hole of M16x1.5 thread. Apply the recommended torque of 21.1 N·m to avoid case distortion. Ensure thread engagement does not exceed 24 mm. Use finger-tight torque for the connector, and avoid exceeding 0.565 N·m. The minimum bend radius of 25.4 mm must be maintained along the cable path to prevent stress damage.
Maintenance & Reliability
Periodically verify the probe DC resistance between center and outer conductors; the 5.0 meter probe should measure 7.2 ± 0.8 ohms. Exposure to temperatures below -34°C may degrade the pressure seal. The probe’s PPS tip and stainless steel case resist corrosion and wear, extending service life in harsh environments.
Selection Guide
When ordering, confirm the cable length (5.0 meters for use with matching Proximitor sensors), connector type (miniature coaxial ClickLoc), and approval option (05 for multiple approvals).
