BENTLY 3500/42M-01-00 4-channel monitor

The BENTLY 3500/42M-01-00 is a 4-channel monitor manufactured by Bently Nevada, primarily designed for vibration and position measurement. Below is its detailed information:

1. Product Overview

The 3500/42M-01-00 can receive signals from eddy current sensors and seismic sensors. Each channel can be programmed using the 3500 frame configuration software, and it is capable of performing measurement functions including radial vibration, axial displacement, differential expansion, eccentricity, REBAM (Rotor Eccentricity and Bearing Condition Monitoring), acceleration, velocity, and shaft absolute vibration.

2. Technical Parameters

Input Signals: Accepts signals from 1 to 4 displacement, velocity, or acceleration sensors.
Input Impedance: 10 kΩ for standard I/O (displacement and acceleration inputs).
Power Consumption: Typical power draw is 7.7 watts.
Sensitivity:
- Radial vibration: 3.94 mV/µm (100 mV/mil) or 7.87 mV/µm (200 mV/mil);
- Axial displacement: 3.94 mV/µm (100 mV/mil) or 7.87 mV/µm (200 mV/mil);
- Eccentricity: 3.94 mV/µm (100 mV/mil) or 7.87 mV/µm (200 mV/mil), etc.
Outputs:
- Front-panel LED indicators for OK, TX/RX, and Bypass status;
- Sensor buffered output impedance: 550 Ω;
- Shaft absolute vibration buffered output impedance: 300 Ω.

3. Product Features

Versatile Functions: Capable of measuring multiple vibration and position parameters. Channels are programmed in pairs, allowing it to perform up to two functions simultaneously, meeting diverse monitoring requirements.
High Precision: Measurement accuracy is generally within ±0.33% of full scale, with a maximum deviation of ±1%, enabling accurate monitoring of equipment operating conditions.
High Reliability: Complies with the American Petroleum Institute (API) 670 standard. All modules and power supplies (when redundant power supplies are used) can be hot-swapped in the frame (inserted or removed while energized), featuring high integration and fault tolerance.
