The Bently Nevada 190501-11-00-04 Velomitor CT provides accurate velocity measurements for predictive maintenance and machine protection. This sensor converts mechanical vibration into an electrical signal proportional to velocity. Its piezoelectric design ensures stable performance across a broad temperature range. Moreover, the 190501-11-00-04 suits both safe and hazardous locations due to its intrinsic safety certifications.
You can mount this transducer in any orientation, which simplifies installation in tight spaces. Additionally, the internal electronics isolate from the case, reducing ground loop issues. The device supports cable runs up to 305 meters without signal degradation. Therefore, it is ideal for large industrial facilities.
The Bently Nevada 190501-11-00-04 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%. Its 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 (90 to 60,000 cpm) ±3.0 dB. The output bias voltage is 10.1 Vdc ± 1.0 Vdc on Pin A relative to Pin B.
Furthermore, the dynamic output impedance stays below 400 Ω typically. The broadband noise level is only 0.229 mm/s (0.009 in/s) peak. Amplitude linearity reaches ±2% up to 63.5 mm/s peak (2.5 in/s peak). The mounted resonant frequency is 9 kHz minimum when stud-mounted.
Temperature sensitivity varies from -8% to +5% typical over the operating range. Transverse response is less than 5% of the axial sensitivity. Base strain sensitivity measures 0.43 mm/s/μstrain (0.017 in/s/μstrain). Grounding is internal, with electronics isolated from the case.
This transducer operates reliably from -40°C to +85°C (-40°F to +185°F) and stores safely between -40°C and +100°C. It withstands shock up to 5000 g peak. The humidity limit is 100% condensing (non-submerged). Magnetic field susceptibility is less than 0.0068 mm/s/gauss at 50 gauss, 50-60 Hz.
The 190501-11-00-04 carries multiple certifications. For intrinsic safety, it meets Ex ia IIC T4 and AEx ia IIC T4 for Class I, Division 1, Groups A-D; Class II, Groups E-G; and Class III. Additionally, it holds Ex nL IIC T4 and AEx nA T4 for Class I, Division 2, Groups A-D. The temperature class is T4 from -40°C to +100°C ambient. Install per drawing 167536.
The unit weighs less than 297 g (10.5 oz). Its mounting surface diameter is 33 mm (1.3 in), and the overall height is 82 mm (3.2 in). The case and connector are both made of 316L stainless steel, ensuring corrosion resistance.
This version includes the plate stud option: 3/8-in 24 to 1/4-in 28. Apply mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The transducer can be mounted at any angle. Polarity: Pin A goes positive relative to Pin B when velocity moves from base to top.
You can extend cable up to 305 metres (1,000 ft.) using part number 02173006 without any signal degradation. This feature gives you flexibility for remote monitoring installations.
Follow these steps for proper installation of the 190501-11-00-04. First, prepare a clean mounting surface with a 33 mm diameter flat area. Next, screw the plate stud into the mounting hole using the specified torque. Then, connect the MIL-C-5015 interface to the mating connector. Finally, verify the polarity by checking that Pin A goes positive with respect to Pin B when velocity directs from base to top.
Remember to keep the mounting surface free from debris and burrs. For hazardous area installations, always follow drawing 167536 and local regulations. Do not submerge the transducer in liquid, although it tolerates 100% condensing humidity.
