The Bently Nevada 200350 / 200355 Accelerometers are general purpose, case-mounted seismic transducers designed for use with Trendmaster Pro Constant Current Direct Input Card 149811-02 and the Seismic Direct Input Card 164746-01. The 200350 and 200355 Accelerometers are contained within a hermetically sealed, stainless steel case. The design provides an extremely rugged transducer, well suited for harsh industrial environments. Each transducer's top mounted, 2-pin connector (MIL-C-5015) allows for easy installation and removal of the interconnecting signal cable. A 1/4-28 threaded hole on the bottom of the casing accommodates multiple mounting options.

The Bently Nevada
200350/200355 Accelerometers are general-purpose, case-mounted seismic transducers. They are primarily designed to work with the Trendmaster Pro constant current direct input card 149811-02 and the seismic direct input card 164746-01
24.
- Sturdy Construction: Housed in a hermetically sealed stainless steel case, they are extremely rugged and well-suited for harsh industrial environments, ensuring reliable operation even in adverse conditions24.
- Easy Installation and Removal: Each transducer is equipped with a top-mounted 2-pin connector (Mil-C-5015), which enables convenient installation and removal of the interconnecting signal cable. Additionally, a 1/4-28 threaded hole at the bottom of the casing offers multiple mounting options24.
- Wide Measuring Range: They have a measuring range of ±50 g, making them capable of detecting a wide range of accelerations24.
- High Sensitivity: The 200350 model has a sensitivity of 100 mV/g ±20% (1.2 mV/g ±20%), while the 200355 model offers a higher precision with a sensitivity of 100 mV/g ±5% (1.2 mV/g ±5%)2.
- Broad Frequency Response: The 200350 has a frequency range of 30 to 600,000 cpm (0.5 to 10,000 Hz), and the 200355 can cover 12 to 600,000 cpm (0.2 to 10,000 Hz), accommodating various vibration frequencies in different industrial applications2.
- Wide Operating Temperature Range: They can operate within the temperature range of -65 to 250 °F (-54 to 121 °C), demonstrating excellent thermal stability24.
These accelerometers contain a piezoelectric sensing device. When subjected to vibration, the piezoelectric disc generates charge due to the acceleration force from the housing mass. The charge is then electronically converted into a differential voltage signal that is proportional to the acceleration parallel to the sensor's sensitive axis34.
The Bently Nevada 200350/200355 Accelerometers are widely used in the monitoring of large and medium-sized rotating machinery such as steam turbines, hydroturbines, blowers, compressors, and gearboxes. They play a vital role in power, petroleum, chemical, and metallurgical industries, contributing to the online measurement and protection of machinery by accurately measuring the vibration of the machinery's casing13.
In conclusion, the Bently Nevada 200350/200355 Accelerometers are reliable and accurate measurement tools. Their advanced features and robust design make them an ideal choice for industrial vibration monitoring, helping to ensure the safe and efficient operation of industrial machinery.
