The Bently Nevada 190501-12-00-01 is a premier Velocity Transducer engineered for precise seismic velocity measurements on rotating and reciprocating machinery. This model offers a stable 3.94 mV/mm/s sensitivity and a broad frequency response. Consequently, it suits a wide range of condition monitoring applications. Its robust design ensures long-term reliability.
The core of this sensor lies in its exceptional electrical performance. For instance, the Bently Nevada 190501-12-00-01 delivers a standard sensitivity of 3.94 mV/mm/s (100 mV/in/s) with a ±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 from 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) at ±3.0 dB. Additionally, its output bias voltage is a stable 10.1 Vdc ± 1.0 Vdc.
Furthermore, the device exhibits minimal transverse response, less than 5% of the axial sensitivity. Therefore, it ensures accurate readings. The amplitude linearity is excellent at ±2% up to 63.5 mm/s pk. Meanwhile, the mounted resonant frequency is a minimum of 9 kHz, which is critical for avoiding interference from machine structural resonances. The dynamic output impedance is typically less than 400 Ω.
Constructed for resilience, this model features a case made from 316L stainless steel. Its connector is a 2-pin 316L stainless steel MIL-C-5015 type, located on top. The Bently Nevada 190501-12-00-01 operates reliably in extreme temperatures, from -40°C to +85°C. Similarly, you can store it between -40°C and +100°C. It can withstand a shock limit of 5000 g pk. Furthermore, it operates in 100% condensing humidity conditions.
Moreover, the unit's internal electronics are isolated from the case, which helps to prevent ground loops. The mounting torque specification is precise at 4.5 N-m ± 0.6 N-m. You can mount the sensor in any orientation. Consequently, this provides flexibility during installation. Its magnetic field susceptibility is low, at <0.0068 mm/s/gauss.
Mounting is simplified with the plate stud option (3/8-in 24 to M8x1). For connectivity, the device uses a MIL-C-5015 connection interface. The cable length can extend up to 305 metres (1,000 ft.) without signal degradation. This is a significant advantage for remote monitoring setups. The polarity is clearly defined: Pin A goes positive with respect to Pin B when velocity is from base to top.
For hazardous areas, the 190501-12-00-01 comes with crucial approvals. Specifically, its agency approval option (01) includes CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1). Therefore, it meets rigorous safety standards. For intrinsically safe applications, it complies with Ex ia IIC T4 standards. Additionally, you can install it per drawing 167536.
This device also complies with FCC Part 15, the EMC Directive 2014/30/EU, and the RoHS Directive 2011/65/EU. Thus, it confirms its adherence to international regulatory standards.
