Product Overview
When machinery vibration threatens uptime, the Bently Nevada 190501-02-00-01 Velomitor CT Velocity Transducer provides reliable, continuous monitoring. This industrial-grade sensor converts mechanical velocity into a proportional electrical signal, enabling early detection of bearing wear, imbalance, and misalignment. Designed for harsh environments, it offers intrinsic safety approvals and robust stainless steel construction.
Technical Specifications Breakdown
The 190501-02-00-01 delivers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate vibration measurement across a frequency response of 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, extending to 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB. Its output bias voltage is 10.1 Vdc ± 1.0 Vdc, with a dynamic output impedance of less than 400 Ω typical. The transducer operates from -40°C to +85°C and withstands shock up to 5000 g pk. Housed in a 316L stainless steel case, it weighs less than 297 g and measures 82 mm in height with a 33 mm diameter mounting surface.
Industry Applications
In petrochemical plants, the 190501-02-00-01 monitors critical pumps and compressors in Class I, Division 1 hazardous areas. Its intrinsic safety certification (Ex ia IIC T4) allows direct installation in Zone 0/1 environments without additional barriers. For power generation turbines, the transducer's 9 kHz minimum mounted resonant frequency ensures accurate readings even under high-frequency vibrations. The unit's 305-meter maximum cable length (using part number 02173006) enables remote monitoring without signal degradation.
Installation & Setup Guidance
Mount the 190501-02-00-01 using the included 3/8-24 to 1/2-20 stud option. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The transducer can be oriented at any angle, with polarity defined as Pin A going positive relative to Pin B when velocity moves from base to top. Use the MIL-C-5015 connection interface for secure, weatherproof connections. Always follow drawing 167536 for intrinsic safety installations.
Maintenance & Reliability
With no moving parts and internal electronics isolated from the case, the 190501-02-00-01 requires minimal maintenance. Its 316L stainless steel construction resists corrosion in condensing humidity environments. The transducer's temperature sensitivity varies only -8% to +5% across the full operating range, ensuring stable performance. Periodic visual inspection of the cable and connector is recommended to maintain signal integrity.
Selection Guide & Purchasing Advice
Before ordering the 190501-02-00-01, verify your required agency approval option. This unit includes CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1) certifications. Confirm the mounting hardware option (02 stud) and connection interface (00 MIL-C-5015) match your installation.
