The Bently Nevada 190501-04-00-04 is a premium Velocity Transducer engineered for accurate seismic velocity monitoring on critical rotating equipment. This model offers a stable 3.94 mV/mm/s sensitivity and an extensive frequency response range. Consequently, it serves as an ideal solution for predictive maintenance and vibration analysis programs. Its robust 316L stainless steel construction ensures outstanding durability in harsh industrial settings.
The sensor's exceptional electrical performance distinguishes it from conventional transducers. For instance, the Bently Nevada 190501-04-00-04 delivers a standard sensitivity of 3.94 mV/mm/s (100 mV/in/s) with a precise ±5% tolerance. Its frequency response spans from 3.0 Hz to 900 Hz (180 to 54,000 cpm) at ±1.0 dB. Moreover, it extends to a broader range from 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) at ±3.0 dB. Additionally, the output bias voltage maintains a consistent 10.1 Vdc ± 1.0 Vdc.
Furthermore, the device exhibits minimal transverse response, measuring less than 5% of the axial sensitivity. Therefore, this guarantees highly accurate measurement data. The amplitude linearity reaches an impressive ±2% up to 63.5 mm/s pk. Meanwhile, the mounted resonant frequency achieves a minimum of 9 kHz, which effectively prevents interference from machine structural resonances. The dynamic output impedance typically remains below 400 Ω.
Built for extreme environments, this model features a case manufactured entirely from 316L stainless steel. Its connector is a 2-pin 316L stainless steel MIL-C-5015 type, strategically positioned on the top for convenient access. The Bently Nevada 190501-04-00-04 operates reliably across severe temperature ranges, from -40°C to +85°C. Similarly, you can store it safely between -40°C and +100°C. It withstands a maximum shock limit of 5000 g pk. Furthermore, it functions effectively in 100% condensing humidity conditions, provided the unit remains non-submerged.
Moreover, the internal electronics are isolated from the case, which effectively eliminates ground loop complications. The mounting torque specification requires 4.5 N-m ± 0.6 N-m. You can install the sensor in any orientation. Consequently, this offers exceptional flexibility for diverse mounting scenarios. Its magnetic field susceptibility remains impressively low at <0.0068 mm/s/gauss.
This model features a versatile mounting hardware configuration: an M6x1 stud with a 3/8-in 24 adapter. This design accommodates different thread requirements across various machinery platforms. For connectivity, the device utilizes a standard MIL-C-5015 connection interface. The cable length can extend up to 305 metres (1,000 ft.) without any signal degradation. This represents a significant advantage for remote monitoring installations. The polarity is straightforward: Pin A goes positive relative to Pin B when velocity moves from base to top.
For hazardous area applications, the 190501-04-00-04 carries comprehensive safety approvals. Specifically, its agency approval option (04) includes CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1). Therefore, it meets the most rigorous international safety standards for explosive atmospheres. For intrinsically safe installations, it complies with Ex ia IIC T4 requirements. Additionally, you must install it per drawing 167536 to ensure proper compliance.
This device also complies with FCC Part 15 regulations, the EMC Directive 2014/30/EU, and the RoHS Directive 2011/65/EU. Thus, it confirms full adherence to global regulatory requirements.
