133396-01 | Bently Nevada | Overspeed Detection I/O Module

The 133396-01 Overspeed Detection I/O Module of Bently Nevada is part of the 3500/53 electronic overspeed detection system and is used in the 3500 series mechanical detection system. The following is its related introduction:

Function and application:

Signal reception and processing: Receive rotational speed pulse input signals from proximity sensors (such as eddy current sensors) or magnetoelectric sensors, with a signal range of +10.0V to -24.0V. It can process signals applicable to various sensors such as Bentley 3300 8mm eddy current sensor and 3300 16mm high-temperature eddy current sensor (HTPS).

Overspeed protection: Continuously compare the current machine speed with the alarm setting point in the configuration. When the speed exceeds the set value, drive an alarm to achieve machine protection, providing important machine speed information for operation personnel and maintenance personnel.

Voting system support: It can be combined with other modules to form a 2-in-2 or 3-in-2 voting system to enhance the reliability of overspeed protection and is suitable for occasions with extremely high safety requirements.

Application fields: The 3500 system is used for continuous monitoring of rotating and reciprocating machinery in various industries, such as large motors, compressors, steam turbines and other equipment in the petroleum, chemical, power and other industries. It is particularly suitable for automatic shutdown mechanical protection applications that require extremely high reliability and availability.

The relevant system requirements: The overspeed detection system requires 3,500 racks to be equipped with multiple power supplies to ensure stable power supply under all circumstances and guarantee the reliability and continuity of the overspeed detection function.
