BENTLY 86517-01-01-01-02 Sensor Product Information

1、 Product Overview

BENTLY 86517-01-01-01-02 is an accelerometer interface module produced by Bently Nevada. This module is mainly used in the fields of industrial monitoring, vibration analysis, and machine condition evaluation, and is an important component of the rotating machinery condition monitoring system.

2、 Core functions

Signal interface and conversion: As a bridge between the accelerometer and the monitoring system, this module is responsible for receiving the raw signals output by the accelerometer and performing necessary conversions (such as analog-to-digital conversion) to ensure that the signals can be accurately recognized by subsequent systems (such as PLC, DCS).

Signal amplification and processing: The module has a built-in amplification circuit that can adjust the gain of weak acceleration signals, while eliminating noise interference through filtering algorithms to improve signal quality. In addition, some models also support integration operations, converting acceleration signals into velocity or displacement data to meet different monitoring needs.

Compatibility and Scalability: Designed to be compatible with multiple types of accelerometers (such as piezoelectric and MEMS), and support seamless integration with Bently 3300 series vibration monitoring devices. The modular structure allows users to expand the number of channels or functional modules according to their actual needs.

3、 Technical specifications

Input voltage: 110V-380V

Current: 1A-30A

Power: 5W-130W

Sensitivity of accelerometer: The accelerometer used with the 86517 interface module must have a sensitivity of 50 picocoulombs/gram or 100 picocoulombs/gram and necessary connectors.

Cable capacitance: The total pole to pole capacitance of the accelerometer plus the distributed cable capacitance should not exceed 8300 picofarads.

Low noise characteristics: Extension cables must have special low noise characteristics and be able to resist high temperatures and corrosive environments. Low noise structure is a conductive treatment applied to the surfaces between the central conductor and the medium, as well as between the medium and the internal shield, to minimize the generation of charges between the surfaces during cable movement or vibration.

4、 Usage scenarios

Rotating machinery monitoring: widely used for vibration monitoring of high-speed rotating equipment such as steam turbines, gas turbines, compressors, etc. By analyzing acceleration data in real time, potential faults such as rotor imbalance and shaft misalignment can be detected in advance.

Structural health monitoring: In large structures such as bridges and buildings, modules can be connected to accelerometers for long-term monitoring of vibration response, evaluating the safety of the structure under dynamic loads such as wind and earthquake.

Industrial process control: Integrated with PLC and DCS systems, providing equipment status feedback for process industries such as chemical and metallurgical industries, achieving preventive maintenance based on vibration parameters, and reducing unplanned downtime.

5、 Size and weight
