Woodward LR20949 Measuring Transducer

Product Introduction

The Woodward LR20949 Measuring Transducer is a precision industrial device designed to convert analog or mechanical signals into standardized electrical outputs for monitoring, control, and feedback purposes. Engineered for high-reliability applications, this transducer provides accurate measurement of parameters such as speed, position, pressure, or torque depending on system configuration. The LR20949 is widely used in power generation, engine control, and process automation systems, where precise measurement is critical for maintaining operational stability and safety. Its robust design ensures consistent performance under harsh environmental conditions, making it suitable for industrial, marine, and energy applications.

Product Parameters

Applications

The LR20949 Measuring Transducer is designed for accurate signal conversion and measurement in industrial systems, including:

• Engine and Generator Control – monitoring speed, torque, and position for precise control and protection.

• Power Generation Plants – feeding accurate measurement signals to control systems for load balancing and monitoring.

• Industrial Automation – providing feedback signals to PLCs and SCADA systems.

• Marine and Offshore Equipment – high-reliability measurement under harsh marine environments.

• Process Control Systems – converting mechanical or analog process signals into standardized electrical outputs for centralized monitoring.

Its high accuracy and rapid response make it ideal for critical systems where precise feedback is essential to maintain operational efficiency and safety.
