-
Dynamic Output Impedance: <400 Ω typical.
-
Mounted Resonant Frequency: 9 kHz minimum (stud mounted).
These specifications ensure accurate velocity readings across a wide frequency range, essential for early fault detection in bearings, gears, and rotating shafts.
Industry Applications
The 190501-12-99-02 is ideal for vibration monitoring in:
- Pumps and motors
- Compressors and turbines
- Generators and gearboxes
Its intrinsic safety approvals (ATEX/IECEx/CSA) allow installation in hazardous areas, making it a versatile choice for oil & gas, chemical, and power generation facilities.
Installation & Setup Guidance
Proper mounting is critical for accurate readings. The transducer uses a 3/8-24 plate stud (M8x1) and accepts any orientation. Apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). Ensure the mounting surface is clean and flat. The unit comes with a 32-foot cable; for longer runs, up to 305 meters (1,000 ft) of cable (part number 02173006) can be used without signal degradation.
Maintenance & Reliability
With a robust 316L stainless steel case and sealed electronics, the 190501-12-99-02 requires minimal maintenance. Its operating temperature range of -40°C to +85°C and shock limit of 5000 g pk ensure reliable performance in demanding conditions. Periodic inspection of the cable and mounting integrity is recommended to maintain measurement accuracy.
Compatibility & Integration
This transducer integrates seamlessly with Bently Nevada vibration monitoring systems and other industrial automation modules. The 2-pin 316L stainless steel MIL-C5015 connector ensures secure connections. Its output bias voltage and impedance are compatible with standard data acquisition systems.
