Reverse Engineering / Indigenous Development of Cooling Liquid Level Sensor - T80 UD Tank

Abstract

This study presents the development of a cost-effective and reliable coolant liquid level sensor for heavy-duty automotive and industrial machinery. The paper introduces a novel sensor structure designed to address the limitations of traditional sensors, focusing on enhanced ruggedness and reliability in extreme temperatures and undulating terrains. The research emphasizes the need to replace conventional sensors with a more dependable alternative, aiming to provide accurate and consistent readings under challenging conditions. This is achieved by leveraging a magnetic float and reed switch mechanism, which eliminates the need for nontraditional level sensing methods. Real-time data acquisition is facilitated by the reed switch and magnetic float system, with experimental tests conducted on heavy-duty vehicles under various extreme conditions. Despite the availability of advanced digital sensors, magnetic float valves remain prevalent due to their reliability and ruggedness in nature.
