Functional Description

8270-360 is a 2301 Speed Sensor Module developed by Woodward. The module control and monitoring of speed-related parameters in various industrial applications. It seamlessly integrates with the application program to process inputs from MPU (Motion Pickup Unit) and proximity probes, providing essential speed information to the application software.

Features

• One of the notable features of the Analog Combo module is its ability to offer derivative output if required by the application. This additional output can be valuable for certain control strategies and fine-tuning of speed-dependent processes.
• The module also incorporates a configurable filter for the speed sensor inputs, allowing the application software to select a filter time constant of either 8 milliseconds or 16 milliseconds. In most applications, the 8-millisecond filter time constant should suffice, providing quick and accurate speed readings. However, for very slow speed applications, the 16-millisecond filter time constant may be necessary to ensure precision in speed detection.
• The speed range setting on the module determines the maximum speed that it can reliably detect. Additionally, the control output of the software is designed to detect a minimum speed of one fiftieth of the selected speed range. This feature is crucial in identifying potential issues, such as failed speed sensors, which could lead to inaccurate readings and, in extreme cases, overspeed conditions at very low speeds. By detecting slow updates at low speeds, the module aids in preventing potentially hazardous situations.
• Moreover, the monitor output of the GAP block provides a continuous readout down to 0.5 Hz, irrespective of the speed range. This ensures that even extremely low-speed conditions are accurately monitored, enhancing the safety and efficiency of the application.
• The versatility of the Analog Combo module allows an application to employ any combination of accepted MPU and proximity probes, tailoring the speed sensing capabilities to the specific requirements of the system. Additionally, different speed ranges can be utilized as needed, accommodating a wide range of applications with varying speed requirements.

Frequently Asked Questions

What is 8270-360?
It is a 2301 Speed Sensor Module developed by Woodward.

How is the speed sensor input filtered, and can the filter time constant be adjusted?
The module incorporates a configurable filter for the speed sensor inputs. The application software can choose between two filter time constants: 8 milliseconds and 16 milliseconds. The 8-millisecond filter is suitable for most applications, providing quick and accurate speed readings, while the 16-millisecond filter is ideal for very slow speed applications, ensuring precise speed detection.

What role does the speed range setting play in speed detection?
The speed range setting determines the maximum speed that the module can reliably detect. Additionally, the control output of the software is designed to detect a minimum speed of one fiftieth of the selected speed range. This crucial feature helps identify potential issues, such as failed speed sensors, which could lead to inaccurate readings and, in extreme cases, overspeed conditions at very low speeds. By detecting slow updates at low speeds, the module aids in preventing potentially hazardous situations.
