Bently Nevada 133396-01 3500/53/54 Overspeed Detection I/O Module

Bently Nevada 133396-01 is an overspeed detection I/O module in the 3500 series. It belongs to the 3500/53 electronic overspeed detection system and is mainly used for overspeed protection of mechanical equipment. The following is a detailed introduction:

Functional characteristics:

Overspeed detection: It is used to continuously monitor the speed of rotating and reciprocating machinery. It is a highly reliable and fast-responding redundant tachometer system. It can monitor the speed of mechanical equipment in real time and send out an alarm signal when the speed exceeds the preset threshold. It realizes overspeed protection function and meets the overspeed protection requirements of American Petroleum Institute (API) standards 670 and 612.

Signal processing: Each module can receive a single sensor signal from a proximity probe sensor or magnetic pickup. The input signal voltage range is + 10.0V to - 24.0V. Signals outside this range will be limited by the module internally.

Technical parameters:

Input impedance: 20kΩ.

Power consumption: typically 8.0W.

Sensor compatibility: Supports multiple types of sensors such as Bently Nevada 3300 8 mm eddy current sensor, 3300 16 mm high temperature eddy current sensor (HTPS).

Alarm settings: The set point is set through software configuration and can usually be adjusted between 0 and 100% of the full scale.

Output: Provides multiple output options such as proportional output value, recorder output and relay output.

Working environment: The operating temperature range is - 30°C to + 65°C, which is suitable for harsh industrial environments.

Appearance and installation: Generally adopts standard installation method, can be installed in the 3500 series frame, easy to integrate and maintain the system, and weighs about 0.45kg.

System composition and application: It can form a 2-out-of-2 or 3-out-of-2 (recommended) voting system with other modules. As part of the 3500 machine management and protection system, it provides high-reliability overspeed protection for mechanical equipment. It is widely used in automatic shutdown mechanical protection applications that require extremely high reliability and availability, such as rotating mechanical equipment in the petroleum, chemical, electric power and other industries.
