The 2300/25 Vibration Monitor is a cost-effective continuous vibration monitoring and protection device launched by Bently Nevada. It is specially designed for medium and low criticality mechanical equipment, and is suitable for various industries such as oil and gas, power generation, water treatment, papermaking, manufacturing, mining, and cement. Its core function is to continuously monitor equipment and issue alarms when vibration levels are too high. It can be used for various units or independent enclosures where the number of sensor points matches the number of monitor channels, and supports advanced signal processing.

2300/25 Vibration Monitor Core Functions & Features
Monitoring & Protection:
Provides continuous vibration monitoring and protection, supporting real-time measurement of critical parameters such as acceleration, velocity, and displacement. Configurable alarms are available.
Input Channels:
- Two acceleration/velocity/proximity input channels supporting synchronous sampling for advanced diagnostics.
- One dedicated speed channel compatible with proximity probes, magnetoelectric sensors, and proximity switch-type sensors.
- All three input channels support process variables.
Measurement Parameters:
Real-time provision of multiple critical measurements, including:
- Acceleration peak (Acceleration pk),
- Acceleration root mean square (Acceleration rms),
- Acceleration peak-to-rms ratio (Acceleration pk/rms),
- Velocity peak (Velocity pk),
- Velocity root mean square (Velocity rms),
- Displacement peak-to-peak (Displacement pp),
- Displacement root mean square (Displacement rms),
- Speed.
All parameters are configurable with alarms.
Measurement Groups:
Each channel includes one measurement group and two additional band-pass measurements.
