Introduction
When machinery vibration threatens uptime in hazardous areas, the Bently Nevada 190501-10-00-02 Velomitor CT Velocity Transducer delivers reliable, accurate measurements. This sensor is engineered for continuous monitoring in demanding industrial applications, from rotating equipment to structural health.
Technical Specifications Breakdown
The 190501-10-00-02 provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring 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, covering critical vibration bands. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, with a dynamic output impedance of <400 Ω typical. A mounted resonant frequency of 9 kHz minimum (stud mounted, except quick disconnect) guarantees stability.
Industry Applications
In petrochemical plants, the 190501-10-00-02 monitors pumps and compressors in Class I, Division 1 areas, thanks to its ATEX/IECEx/CSA (Class I, Zone 0/1) certification. For power generation, it tracks turbine vibration with ±2% amplitude linearity up to 63.5 mm/s pk. The stainless steel case and 100% condensing humidity tolerance make it suitable for offshore platforms.
Installation & Setup Guidance
Mount the transducer using the provided M6x1 stud with 3/8-24 adapter, applying a torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The MIL-C-5015 connector ensures a secure connection. Any orientation is acceptable, but ensure the mounting surface is clean and flat (33 mm diameter). Maximum cable length is 305 metres (1,000 ft.) with part number 02173006 without signal degradation.
Maintenance & Reliability
The internal electronics are isolated from the case, reducing ground loop issues. With a shock limit of 5000 g pk and operating temperature range of -40°C to +85°C (-40°F to +185°F), this transducer withstands severe conditions. Periodic inspection of the connector and cable integrity is recommended. The broad temperature sensitivity of -8% to +5% typical ensures consistent performance across the range.
Compatibility & Integration
The 190501-10-00-02 integrates with Bently Nevada vibration monitoring systems and data acquisition platforms. Its 2-pin MIL-C-5015 connector simplifies wiring: Pin A goes positive with respect to Pin B when velocity is from base to top. The transducer is intrinsically safe Ex ia IIC T4 per drawing 167536, suitable for Class I, Div 1, Groups A, B, C, D.
Selection Guide & Purchasing Advice
Before ordering, verify agency approval option 02 (CSA/NRTL/C, ATEX/IECEx/CSA) matches your zone requirements. The 190501-10-00-02 weighs 0.297 kg and has a height of 82 mm (3.2 in).
