The Bently Nevada 190501-12-00-CN is a high-performance velocity transducer for permanent vibration monitoring on rotating machinery. This Velomitor CT model features a top-exit MIL-C-5015 connector and an M8x1 stud mounting plate. It delivers reliable data for predictive maintenance and machine protection systems.
The 190501-12-00-CN offers precise electrical characteristics for accurate vibration measurement. Its sensitivity reaches 3.94 mV/mm/s (100 mV/in/s) ±5% . The frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, with an extended range of 1.5 Hz to 1.0 kHz at ±3.0 dB.
Additionally, this sensor features a typical output bias voltage of 10.1 Vdc ± 1.0 Vdc on Pin A relative to Pin B. Its dynamic output impedance stays below 400 Ω. The amplitude linearity remains within ±2% up to 63.5 mm/s peak. Furthermore, the mounted resonant frequency reaches 9 kHz minimum when stud mounted.
This transducer operates reliably under extreme conditions. The operating temperature range spans from -40°C to +85°C, while storage allows up to +100°C. It withstands a maximum shock limit of 5000 g peak. The case uses 316L stainless steel, ensuring corrosion resistance in harsh environments.
Moreover, the Bently Nevada 190501-12-00-CN is fully sealed against humidity, handling 100% condensing conditions without submersion. Its magnetic field susceptibility is extremely low at <0.0068 mm/s/gauss. The internal electronics are isolated from the case, which simplifies grounding and reduces noise.
Proper installation ensures optimal performance. The mounting surface requires a 33 mm diameter flat area. The total height is 82 mm, and the weight is under 297 g. Use the supplied M8x1 stud plate for attachment. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf) .
The polarity is clearly defined: Pin A goes positive with respect to Pin B when velocity directs from base to top. You can mount this sensor at any angle without affecting its response. For cable runs, it supports up to 305 metres (1,000 ft.) of cable (part number 02173006) without signal degradation.
This specific variant, 190501-12-00-CN, includes country-specific approvals for the Chinese market. It meets the intrinsic safety requirements with Ex ia IIC T4 rating for Class I, Division 1, Groups A, B, C, and D. It also carries CSA/NRTL/C certification for hazardous locations.
Additionally, it supports non-incendive operation with Ex nL IIC T4 for Class I, Division 2 areas. The temperature class is T4, rated for ambient temperatures from -40°C to +100°C. Always install per drawing 167536 to maintain safety compliance.
The Bently Nevada 190501 delivers consistent data even under challenging conditions. Its transverse response is less than 5% of the axial sensitivity, minimizing cross-axis errors. Base strain sensitivity is rated at 0.43 mm/s/μstrain, ensuring measurements reflect true machine vibration.
The broadband noise floor is only 0.229 mm/s peak, which does not interfere with critical vibration data. Furthermore, temperature sensitivity varies only -8% to +5% typical across the full operating range. This stability makes the 190501-12-00-CN a trusted choice for continuous monitoring.
Each unit is carefully packaged to prevent damage during transit. The package includes one Bently Nevada 190501-12-00-CN velocity transducer with the M8x1 stud plate pre-installed. It also contains the necessary mounting hardware and a quick-start guide.

1. What is the primary application for the Bently Nevada 190501-12-00-CN?
This transducer is mainly used for measuring absolute vibration velocity on compressors, turbines, pumps, and fans in critical industrial processes.
2. What is the difference between this model and the 190501-07-00-01?
The 190501-12-00-CN uses an M8x1 stud plate instead of a 3/8-24 thread, making it suitable for metric mounting systems.
3. Can I use this sensor in a hazardous area?
Yes, the 190501-12-00-CN carries Ex ia IIC T4 certification for Class I, Division 1, and Zone 0/1 environments with proper installation per drawing 167536.
4. What cable length is supported without signal loss?
You can run up to 305 metres (1,000 feet) of cable (Bently Nevada part number 02173006) without any degradation in signal quality.
5. How do I properly ground this velocity transducer?
The internal electronics are isolated from the case. You should reference Pin B to your instrumentation ground, following your system's grounding scheme.
