Frequently Asked Questions (FAQ)

1. What is the minimum operating frequency of the 9200-01-20-10-00?

The Bently Nevada 9200-01-20-10-00 has a minimum operating frequency of 4.5 Hz (270 cpm) with a 0 ±2.5 degree mounting angle.

2. What makes the M10x1 stud different from the 1/4-20 UNC stud?

The M10x1 metric stud on the 9200-01-20-10-00 meets European and Asian mounting standards. The 1/4-20 UNC follows North American standards.

3. Can I extend the 20 ft cable if I need more length?

Yes, you can extend the 9200-01-20-10-00 cable using shielded twisted pair wire. Keep total resistance below 50 ohms for accurate readings.

4. What termination load does this sensor require?

You need a 10 kΩ load between Terminal A and Terminal B for proper sensitivity calibration.

5. Which machines work best with this 4.5 Hz transducer?

This Bently Nevada 9200-01-20-10-00 suits low-speed machines like cooling tower fans, wind turbines, and large slow-speed pumps running above 270 rpm.

Application Scenarios

The Bently Nevada 9200-01-20-10-00 excels in low-speed rotating machinery monitoring. Power plants use it on cooling tower fans and induced draft fans. Wind turbine operators install these sensors on main shaft bearings. The 4.5 Hz minimum frequency captures low speed vibration signals effectively. This feature suits machines running between 270 and 600 rpm. The M10x1 metric stud matches European equipment standards. The 20 ft cable reaches junction boxes without extension cables. Hydroelectric plants monitor turbine guide bearings with this transducer.

Metric Mounting Advantages

The M10x1 metric stud on the 9200-01-20-10-00 offers specific benefits for international users. This mounting thread matches standard metric drilling practices. You can install the transducer without thread adapters. The M10x1 stud provides strong mechanical attachment to the machine casing. This mounting option simplifies spare part management for European and Asian facilities. The circular base distributes mounting force evenly across the surface.

Low Frequency Response Characteristics

The 4.5 Hz minimum operating frequency of the 9200-01-20-10-00 provides advantages for slow machines. This transducer captures vibration signals down to 270 cpm. Low speed machinery often produces vibration at these frequencies. The sensor maintains sensitivity at near-DC conditions. This characteristic enables monitoring of cooling towers and large fans. For machines running below 600 rpm, this transducer delivers complete data. The 0 ±2.5 degree mounting angle requires near-vertical orientation.

Environmental Robustness & Compliance

This 9200-01-20-10-00 transducer withstands dusty industrial environments. The anodized aluminum case resists corrosion from moisture and mild chemicals. Neoprene gaskets prevent dust and water ingress. Relative humidity up to 95% noncondensing does not affect operation. The integral 20 ft cable maintains signal integrity in wet conditions. The sensitivity temperature coefficient of 0.2%/°C ensures stable readings across the full -29°C to +121°C range. This model carries no hazardous area approvals, making it suitable for general purpose use only.

Compatibility Information

The Bently Nevada 9200-01-20-10-00 works with most Bently Nevada monitoring systems. Use it with 1900/65A, 3500, and 2300 series monitors. The 20 mV/mm/s output matches standard velocity input cards. The 10 kΩ termination load requirement matches Bently Nevada barrier and monitor inputs. The 20 ft cable connects directly to junction boxes. For legacy systems, verify the input impedance before connecting. This transducer also works with third party monitors that accept 20 mV/mm/s velocity inputs with 10 kΩ loading.

Cable Length Selection Guide

Choose the 9200-01-20-10-00 when you need a 20 ft pre-attached cable. This length suits most local junction box installations. Select the 20 ft option for mounting distances between 15 and 25 feet from the monitor. For longer runs, extend the cable using proper shielded wire. For shorter runs, coil excess cable neatly. The 50 ft cable option works for remote monitor locations. The side mount or terminal block options work with user-supplied cables.

Conclusion

The Bently Nevada 9200-01-20-10-00 delivers accurate casing velocity measurements for low-speed machine monitoring. Its 4.5 Hz minimum frequency captures slow speed vibration signals effectively.
