Description
Product overview
The core component of the Bently Nevada 3500 family of monitoring systems, the Bently Nevada 3500/22M 138607-01 is a professional dual-channel vibration monitoring module designed specifically for the protection of industrial machinery. The module can simultaneously process vibration signals of two independent channels, support input of speed or acceleration sensors, and is suitable for real-time condition monitoring of key rotating equipment such as steam turbines, compressors, and pump sets. The Bently Nevada 3500/22M 138607-01 features a modular design with a 24-bit ADC converter and dynamic signal processing technology to accurately measure mechanical vibrations in the frequency range 0.5Hz to 10kHz. Its API 670-compliant alarm logic enables four levels of alarm output (warning, danger, ultra-danger, failsafe) to provide reliable predictive maintenance support for industrial equipment.

Main features and advantages
The Bently Nevada 3500/22M 138607-01 is designed with military-grade components and has excellent electromagnetic interference resistance (according to IEC 61000-4) for stable operation in strong electromagnetic environments. Its patented SIL2 certified security architecture ensures reliable transmission of critical alarm signals. The built-in self-diagnosis function of the module can monitor the open/short circuit of the sensor and the abnormal temperature of the module in real time.
Core advantages include:
Dual channel independent processing architecture to avoid signal crosstalk
Configurable filter Settings (high-pass/Low-pass/bandpass)
Support ISO 10816 vibration standard automatic assessment
Waveform capture and spectrum analysis function
The module is hot-swappable and supports online maintenance
Application field
The Bently Nevada 3500/22M 138607-01 is widely used for centrifugal compressor monitoring in the oil and gas industry, steam turbine protection systems in power plants, and vibration control of high-line rolling mills in the metallurgical industry. On offshore RIGS, the module is used for condition monitoring of main propulsion turbines; In chemical plants, it is used to monitor the mechanical health of large reactor agitators. Its corrosion resistant coating design is particularly suitable for high salt spray environments in offshore platforms and coastal power plants.
