72301-01-02-02-05-01-01

Product Overview The Bentley 72301-01-02-02-05-01-01 is a 7200 series dual-channel vibration displacement monitoring module, compatible with the same series of racks. It is equipped with an electro-vortex sensor to collect signals, monitor axial vibration and axial displacement data, and features a hierarchical alarm interlock function. It can output analog signals to upload operational information and is applied to the condition protection monitoring of rotating equipment such as steam turbines, compressors, and generator sets.

Description

Technical Specifications

Powered by the chassis backplane, with full-height card installation form

Dual-channel independent acquisition circuits, compatible with conventional types of eddy current probes

Measurement accuracy meets standards, frequency response range is suitable for equipment operation monitoring requirements

Integrated alarm relay contacts, support for analog signal transmission externally

Operating temperature 0℃ to 60℃, storage temperature -40℃ to 85℃, with dust-proof and shock-proof performance

Installation and Wiring

Insert the module into the designated slot of the chassis and lock it for fixation to ensure good contact of the internal bus

Connect the sensing cables in accordance with the channel sequence to the corresponding ports, separate the strong and weak lines for wiring

Connect the alarm control lines and output lines in a standardized manner, with firm connections without loosening of terminals

After all wiring checks confirm no errors, then power on for debugging and use

Maintenance and Care

Regularly observe the indicator lights on the panel, monitor the values to ensure smooth operation without abnormal fluctuations

Regularly tighten the wiring terminals to check for cable damage, aging, and dirt accumulation

Periodically calibrate the measurement parameters and test whether the alarm response actions are normal

Reduce the frequency of card insertion and removal to protect the interface, store idle components in a dry and ventilated place Fault diagnosis

There is no monitoring data for the channel. Check the power supply, slot contact and the continuity of the sensing lines.

The numerical fluctuations have a large deviation. Adjust the installation gap of the probe and optimize the shielding and grounding of the lines.

The alarm function is malfunctioning. Check the threshold parameters and detect the continuity of the relay contacts.

The signal transmission is abnormal. Check the wiring status and review the relevant configuration settings.
