Case Study: Robust, Reliable Liquid Level Sensors for Defense Applications

Background

In defense environments, systems must be reliable, long-lasting, and durable. They must withstand heat and vibration without faltering. Accurate fuel level readings are crucial for operational safety in combat vehicles and armored personnel carriers. These sensors can also track coolant and oil levels to warn of equipment reliability issues.

Challenge

Sourcing equipment designed specifically for defense use is challenging. These vehicles require rugged, long-lasting sensors that perform reliably under significant shock and vibration. Lesser liquid level sensors can experience reading issues due to vehicle movements in mobile applications. Capacitive solid-state sensors are preferred for their stable readings and lack of sensor dead-zones that affect other technologies such as radar and ultrasound. High-quality materials ensure these liquid sensors consistently deliver reliable performance for critical applications.
