Bently Nevada 190501-08-00-00 Velomitor CT Velocity Transducer

Product Introduction

When a critical rotating machine begins exhibiting subtle vibration changes, the Bently Nevada 190501-08-00-00 Velomitor CT Velocity Transducer delivers precise velocity readings. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB and extends to 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB. This transducer, manufactured by Bently Nevada, provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%. It is designed for continuous monitoring in harsh industrial environments.

Technical Specifications Breakdown

The 190501-08-00-00 features an output bias voltage of 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B. Its dynamic output impedance is less than 400 Ω typical. The transducer maintains amplitude linearity within ±2% to 63.5 mm/s pk (2.5 in/s pk). The mounted resonant frequency is 9 kHz minimum (stud mounted, except quick disconnect). These specifications ensure accurate and reliable vibration data for predictive maintenance programs.

Industry Applications

This velocity transducer excels in monitoring rotating equipment such as turbines, compressors, and pumps. Its wide frequency response and high sensitivity allow early detection of bearing wear, imbalance, and misalignment. The 316L stainless steel case and 100% condensing humidity tolerance make it suitable for offshore platforms, chemical plants, and power generation facilities. The internal electronics are isolated from the case, reducing electrical noise interference.

Installation & Setup Guidance

Mount the transducer using the included plate stud 3/8-in 24 to 1/2-in 20 hardware. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The mounting surface requires a 33 mm diameter (1.3 in diameter) flat area. The transducer can be installed in any orientation. Use the MIL-C-5015 connection interface for secure wiring. Maximum cable length is 305 metres (1,000 ft.) of cable (part number 02173006) with no signal degradation. Ensure proper grounding per installation drawing 167536 for intrinsically safe applications.

Maintenance & Reliability

Routine inspection of the transducer and cable connections ensures long-term reliability. The operating temperature range of -40°C to +85°C (-40°F to +185°F) and storage temperature range of -40°C to +100°C (-40°F to +212°F) allow deployment in extreme conditions. The shock limit of 5000 g pk maximum protects against sudden impacts. Verify the output bias voltage periodically to confirm sensor health.

Selection Guide & Purchasing Advice

Before ordering, verify that the agency approval option matches your site requirements. This model has agency approval option 00 (No Approvals). If intrinsically safe certification is needed, select a variant with approval options 01 through 04. Confirm the mounting hardware option (08 plate stud 3/8-in 24 to 1/2-in 20) fits your installation. BluePLC Industrial offers genuine Bently Nevada products with expert support.
