Bently Nevada 190501-10-00-CN Velocity Transducer

Bently Nevada 190501-10-00-CN Velomitor CT Velocity Transducer

Product Introduction

The Bently Nevada 190501-10-00-CN provides accurate vibration velocity measurements for rotating machinery. You can install this sensor on turbines, compressors, fans, and pumps. It comes with a plate stud mount using an M6x1 to M6x1 thread and a 3/8-24 adapter. Additionally, the device uses a MIL-C-5015 connection interface for secure signal transmission. The internal electronics isolate from the stainless steel case to prevent ground loop interference.

Key Electrical Specifications

Sensitivity reaches 3.94 mV/mm/s (100 mV/in/s) with a ±5% accuracy.
The frequency response spans 3.0 Hz to 900 Hz at ±1.0 dB.
Moreover, you get 1.5 Hz to 1.0 kHz at ±3.0 dB for broader applications.
Output bias voltage measures 10.1 Vdc ± 1.0 Vdc on Pin A relative to Pin B.
Dynamic output impedance stays below 400 Ω under normal conditions.
Broadband noise is only 0.229 mm/s pk, ensuring clean signals.

For amplitude linearity, the Bently Nevada 190501-10-00-CN achieves ±2% up to 63.5 mm/s pk.
Mounted resonant frequency reaches 9 kHz minimum when stud mounted.
Base strain sensitivity equals 0.43 mm/s/μstrain.
You can extend cable length up to 305 meters using part number 02173006 without any signal loss.
Temperature sensitivity changes only -8% to +5% across the full operating range.
Transverse response stays below 5% of the axial sensitivity.

Environmental and Mechanical Limits

Operating temperature ranges from -40°C to +85°C.
Storage temperature goes from -40°C to +100°C.
Shock tolerance reaches 5000 g pk maximum for tough industrial conditions.
Humidity limit allows 100% condensing environments as long as you do not submerge the unit.
Magnetic field susceptibility stays below 0.0068 mm/s/gauss at 50 gauss, 50-60Hz.

Weight is under 297 grams (10.5 oz).
Mounting surface diameter measures 33 mm (1.3 in).
Total height equals 82 mm (3.2 in).
Case material uses 316L stainless steel for excellent corrosion resistance.
Connector type is a 2-pin 316L stainless steel MIL-C-5015 mounted on the top.

Installation and Mounting Guidelines

Mounting torque requires 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in–lbf).
The Bently Nevada 190501-10-00-CN works in any orientation without performance degradation.
Polarity definition: Pin A goes positive with respect to Pin B when velocity moves from the base toward the top.
Mounting hardware includes a plate stud M6x1 to M6x1 with a 3/8-24 adapter.
Therefore, installation is quick and straightforward on most machinery casings.

Frequently Asked Questions (FAQ)

1. What makes the 190501-10-00-CN different from other Bently Nevada velocity transducers?
This CN version carries country-specific approval for the Chinese market. Otherwise, it shares the same 100 mV/in/s sensitivity and stainless steel construction as other 190501 models.

2. Can I use this sensor in a hazardous area without extra protection?
The standard 190501 platform supports intrinsic safety approvals (Ex ia IIC T4). Please verify that your specific CN version includes those certifications by checking the product label or contacting us.

3. How do I connect the Bently Nevada 190501-10-00-CN to my monitoring system?
Use the MIL-C-5015 2-pin connector. Pin A is the positive signal output, and Pin B is the reference. The bias voltage sits at 10.1 Vdc between these two pins.

4. What happens if I exceed the recommended cable length of 305 meters?
Signal degradation and noise interference may occur beyond 305 meters. Therefore, always use the specified cable (part number 02173006) to maintain full performance.

5. Does mounting orientation affect the output polarity?
No. The sensor works at any angle. However, the polarity rule remains fixed: Pin A goes positive when velocity travels from the mounting base toward the top of the transducer.
