Bently Nevada 200350 | Industrial Piezoelectric Accelerometer Vibration Sensor

The Bently Nevada 200350 is a high-performance industrial piezoelectric accelerometer belonging to the 200300 Velomitor sensor series, specially designed for high-frequency absolute vibration monitoring of rotating and reciprocating machinery. Unlike moving-coil velocity sensors (9200, 74712, 47633) limited by mechanical moving parts and narrow frequency bands, and different from the velocity-focused 200305 sensor, the 200350 adopts solid-state piezoelectric sensing technology with no internal wearable components. It excels in capturing high-frequency vibration, impact vibration and early mechanical fault signals, providing accurate acceleration measurement data for equipment condition monitoring, fault diagnosis and machinery protection systems. Fully compatible with Bently Nevada dedicated seismic monitoring cards and mainstream industrial vibration acquisition equipment, it is widely deployed for long-term stable online monitoring of fans, compressors, pumps and heavy industrial rotating equipment.

2. Standard Ordering Code & Model Differentiation

Common Full Model：200350-02-00-00

Core Model Distinction (200350 VS 200355)

Series Internal Differentiation (200350 VS 200305)

The 200305 is a velocity output sensor focusing on medium and low-frequency vibration monitoring; the 200350 is an acceleration output sensor optimized for high-frequency vibration and impact signal acquisition. Users can select according to equipment fault characteristics: velocity for overall vibration trend monitoring, acceleration for early bearing fault, gear wear and high-frequency impact fault detection.

4. Core Product Advantages

The 200350 piezoelectric accelerometer completely abandons the traditional moving-coil mechanical structure, achieving wear-free long-term operation and effectively solving the problem of performance attenuation of mechanical sensors after long-term vibration. Its ultra-wide 0.5Hz–10kHz frequency response covers almost all fault frequency bands of industrial rotating equipment, accurately capturing early subtle faults such as bearing pitting, gear wear and component looseness that are difficult to detect by conventional velocity sensors. The hermetically sealed stainless steel structure provides excellent resistance to dust, humidity and chemical corrosion, adapting to harsh industrial working environments.

With standard industrial interface and universal mounting structure, it features simple on-site installation and convenient later maintenance. Compared with high-precision 200355 sensors, the 200350 has higher cost performance while meeting general industrial monitoring accuracy requirements, making it more suitable for large-scale batch deployment of auxiliary equipment. The stable solid-state piezoelectric induction technology ensures consistent signal output without temperature drift or mechanical failure, greatly improving the reliability of equipment online condition monitoring systems.

5. Industrial Application Scenarios

The Bently Nevada 200350 accelerometer is widely used for high-frequency vibration monitoring of various industrial rotating machinery. In thermal power plants, it monitors high-frequency vibration of boiler fans, induced draft fans, primary fans and auxiliary water pumps for early fault warning. In petrochemical and natural gas industries, it is deployed on centrifugal compressors, screw compressors and process delivery pumps to capture micro-impact vibration signals of mechanical wear. It is also extensively applied in metallurgical heavy industry, building materials, water treatment and manufacturing industries, suitable for condition monitoring of all kinds of medium and high-speed rotating equipment, providing reliable data support for equipment predictive maintenance and safety protection.
