The Bently Nevada 190501-19-00-CN is a high-performance Velomitor CT velocity transducer for permanent vibration monitoring. This sensor provides a DC-coupled output proportional to the casing vibration velocity. Therefore, it serves as an ideal choice for steam, gas, and compressor turbines. Moreover, this particular variant includes a specialized mounting adapter for flexible installation.
This model offers 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 within ±1.0 dB. Furthermore, the amplitude linearity remains within ±2% up to 63.5 mm/s peak. Additionally, the output bias voltage is fixed at 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B. Consequently, the dynamic output impedance stays below 400Ω. Meanwhile, the broadband output is rated at 0.229 mm/s peak, which ensures a low noise floor.
Constructed from 316L stainless steel, the 190501-19-00-CN excels in harsh industrial environments. For instance, it operates flawlessly between -40°C and +85°C. Moreover, it withstands a shock limit of 5000 g pk. Besides that, the internal electronics are isolated from the case to prevent ground loops. Its base strain sensitivity is a minimal 0.43 mm/s/μstrain. In addition, this transducer features a transverse response below 5% of the axial sensitivity. As a result, it minimizes measurement errors effectively. Meanwhile, the magnetic field susceptibility remains below 0.0068 mm/s/gauss.
The unit uses a 2-pin 316L stainless steel MIL-C-5015 top connector for a secure interface. Specifically, the 190501-19-00-CN with Mounting Hardware Option '19' includes an adapter for 3/8-in 24 to 1/4-in 18 NPT threads. This adapter simplifies installation in various piping configurations. The recommended mounting torque is 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in–lbf). Moreover, you can mount it in any orientation without performance loss. Furthermore, the maximum cable length reaches 305 metres (1,000 feet) with no signal degradation. The Country Specific approval option 'CN' meets local regulatory requirements for the Chinese market.
