Industry Applications
This Bently Nevada 330301-000-011-20-90-01-05 probe is ideal for monitoring vibration in steam turbines, gas turbines, compressors, and large motors operating in high-temperature areas. Its ability to maintain scale factor within ±30% of 3.94 V/mm over a 22°C to +350°C range makes it a reliable choice for critical rotating machinery. The ceramic tip offers excellent wear resistance, while the stainless steel armor protects the extension cable in corrosive environments.
Installation and Setup Guidance
Mount the Bently Nevada 330301-000-011-20-90-01-05 into a 3/4-16 UNF threaded hole per the manufacturer’s recommended gap. Ensure the target is at least 30.5 mm in diameter and the shaft diameter exceeds 152 mm for optimal linear range. Route the hardline and extension cable away from sharp edges and high EMI sources. The included extension cable with stainless steel armor simplifies field wiring. Verify probe DC resistance (5.82 Ω) during installation to confirm cable integrity.
Maintenance and Reliability
With a ceramic tip and AISI 316L case, the Bently Nevada 330301-000-011-20-90-01-05 requires minimal periodic inspection. Check cable armor for damage and verify electrical continuity at each preventive maintenance interval. Operating within the -34°C to +350°C range ensures long service life. The probe’s robust construction reduces unscheduled downtime, contributing to overall operational cost savings.
Selection Guide
When ordering the Bently Nevada 330301-000-011-20-90-01-05, verify the unthreaded length, case length, hardline length, and total length options match your application. The default configuration (000-011-20-90-01-05) includes a 0 in unthreaded length, 1.1 in case, 2.0 m hardline, 9.0 m total length, stainless steel armor, and multiple approvals.
