WOODWARD 5466-5001

الوصف

The WOODWARD 5466-5001 is a specialized Speed Sensor Module used in Woodward’s industrial control systems, particularly for the MicroNet Digital Control series (including MicroNet Plus).

What makes this module distinct is its focus on Eddy Probe (Proximity Probe) inputs. Unlike MPU (Magnetic Pick-Up) sensors which detect ferrous discontinuities, Eddy Probes measure the proximity of a metallic surface and are excellent for sensing very low speeds, even down to 1 Hz, and for providing more detailed information about shaft position and vibration.

2. Product Overview:

The WOODWARD 5466-5001 is a 4-channel Speed Sensor Module designed for use with Woodward’s MicroNet Digital Control Series (including MicroNet Plus and often compatible with MicroNet TMR systems). Its primary function is to receive and process speed signals specifically from Eddy Probe (also known as proximity probe or eddy current probe) transducers. This module is particularly adept at measuring very low speeds (down to 1 Hz) and provides crucial speed data for control, protection, and alarming of rotating machinery.

• Product Type: Speed Sensor Module
• Manufacturer: Woodward
• Series: MicroNet Digital Control (MicroNet Plus, MicroNet TMR)
• Channels: 4 channels
• Input Type: Eddy Probe (Proximity Probe)
• Function: Measures and processes rotational speed, and often position/phase, for control and protection.

3. Detailed Product Description:

For precise control and robust protection of critical rotating machinery, understanding both high and very low speeds is essential. The WOODWARD 5466-5001 excels in this area, leveraging Eddy Probe technology to provide highly accurate and versatile speed measurement within Woodward’s advanced control systems.

The 5466-5001 is a 4-channel Speed Sensor Module that slots directly into a MicroNet Plus or MicroNet TMR chassis. Unlike MPU (Magnetic Pick-Up) sensors that generate a signal from passing teeth, Eddy Probes measure changes in an electromagnetic field as a conductive surface (like a shaft) passes by. This allows them to:

• Sense extremely low speeds: Down to 1 Hz, making them ideal for monitoring machines during startup, shutdown, or very slow rotation, or for detecting a “zero speed” condition.
• Provide precise shaft position/phase information: Which can be vital for dynamic balancing, vibration analysis (when combined with other modules), and precise timing.

Each of the module’s four channels independently processes the Eddy Probe input, converting the raw signals into usable speed data for the main CPU. This data is then used by the control system for functions such as:

• Accurate Speed Control: Even at very low RPMs.
• Overspeed Protection: Essential for safety, triggering shutdowns or alarms if speeds exceed safe limits.
• Start-up and Shutdown Sequencing: Monitoring and controlling speeds during critical transitions.
• Reference for Vibration Monitoring: Providing a phase reference for other modules that monitor shaft vibration.

A key feature of the 5466-5001, similar to other modern Woodward speed modules, is that there are no potentiometers or adjustments required. This means the module does not need calibration when installed or replaced, simplifying maintenance and minimizing potential for human error. It can be used in both redundant and simplex systems, offering flexibility to suit various application requirements. For backward compatibility with older systems, it may sometimes need to be paired with a specific item like 5464-834.

Key Features and Benefits:

• 4 Independent Channels: Allows for monitoring of multiple speed/position points on a single machine, providing redundancy or comprehensive data.
• Eddy Probe Input Specific: Optimized for reliable and accurate measurement from proximity probes.
• Excellent Low-Speed Sensing: Capable of detecting speeds as low as 1 Hz, critical for startup, shutdown, and zero-speed detection.
• No Calibration/Adjustment Required: Simplifies installation, maintenance, and replacement, reducing downtime and human error.
• High Accuracy: Delivers precise speed and potentially phase measurements.
• Robust Signal Processing: Includes features like noise filtering to ensure stable readings in challenging industrial environments.
• Broad Compatibility: Compatible with both MicroNet Plus and MicroNet TMR control systems.
• Industry Compliant: Meets standards such as ATEX, CSA, and CE (EMC), ensuring suitability for regulated environments.

Typical Applications:

The WOODWARD 5466-5001 is essential in any application requiring precise speed measurement, especially at low speeds, and sometimes for shaft position or vibration reference, for control and protection of rotating machinery.

• Gas and Steam Turbines: Measuring rotor speed from zero to operational RPM, for precise control during start-up, acceleration, and shutdown, as well as providing overspeed protection and phase reference for vibration monitoring.
• Compressors: Monitoring shaft speed, particularly at low speeds during sequencing, and for surge protection.
• Generators: Measuring generator RPM for synchronization, load sharing, and protection across the full speed range.
• Process Pumps and Motors: Applications where precise speed control, especially at very low speeds, or zero-speed detection is critical.
