BENTLY NEVADA 133442-01 Speed Module
Bently Nevada 133442-01- Analysis of Speed Measurement and Monitoring Module
133442-01 is a commonly used speed monitoring module in Bently Nevada systems, specifically designed for high-speed acquisition and processing of data such as speed, phase, and synchronization signals of rotating machinery. It belongs to the key detection unit in the mechanical protection system and is one of the indispensable modules to ensure the safe and smooth operation of equipment.
◆ 1. High speed speed speed acquisition capability
The module can receive pulse signals from eddy current probes, magneto electric sensors, or photoelectric sensors, and calculate the speed through an internal frequency counting circuit.
Features include:
High sampling speed
Timely response to rapidly changing rotational speeds
Suitable for both low-speed and high-speed equipment
◆ 2. Accurate phase and reference detection
In addition to rotational speed, the module can also recognize phase reference signals (Keyphasor) ® Function), used for:
Shaft vibration analysis
Phase diagnosis
Rotor dynamic balance evaluation
Trend record of unit startup/shutdown
This is very important in large rotating machinery such as turbines, compressors, etc.
◆ 3. Complete speed protection logic
Internally includes operational protection functions, such as:
Overspeed alarm
overspeed trip
Stall detection
Abnormal pulse monitoring
Ensure that the equipment responds promptly before breaking through the safety line.
