Industry Applications
The Bently Nevada 9200-01-20-10-00 is a direct replacement for legacy velocity transducers in critical rotating machinery. Typical applications include:
-
Pump and Motor Vibration Monitoring: The 2.54 mm displacement range and 25 mm/s velocity capability suit centrifugal pumps and electric motors in petrochemical and water treatment plants.
-
Fan and Compressor Protection: With a robust temperature range (-29°C to +121°C), the 9200-01-20-10-00 performs reliably in HVAC or compressed air systems where dust and moisture resistance is essential.
-
Turbine Health Assessment: Upgrade older vibration sensors on steam or gas turbines. The integral 20-foot cable simplifies retrofitting without re-wiring.
Installation & Setup Guidance
Mount the Bently Nevada 9200-01-20-10-00 using the M10x1 stud on a flat, clean surface. The transducer orientation must match the calibrated angle (0 ±2.5 degrees, minimum operating frequency 4.5 Hz). Proper termination with a 10 kΩ load on pins A and B ensures accurate sensitivity. Avoid submersion unless using the integral cable option; the unit is dust and moisture resistant but not submersible. For best performance, ensure the mounting base is circular and tightened to spec.
Selection Guide & Purchasing Advice
Before purchasing the Bently Nevada 9200-01-20-10-00, verify your system's vibration monitoring requirements: the 4.5 Hz minimum frequency suits slow-speed machines. The 20-foot connector length is ideal for most installations; for longer runs, consult your system engineer. This transducer comes with a 12-month factory warranty from PLC Source PRO.
