The Sperry Speed Log 2863 AA Preamplifier is a critical component in the Sperry Marine speed log system, amplifying signals from the speed measurement sensors to provide accurate and real-time speed readings. The preamplifier ensures that weak signals from the transducer are boosted, enabling the speed log to deliver precise speed data, even in challenging environmental conditions. This component plays an essential role in maintaining the accuracy and reliability of the speed log system, which is crucial for effective vessel navigation.
