Low coolant level detection in large tractors is needed to protect the engine from overheating. This requires a simple, reliable sensing solution with long life to handle the conditions often present with agricultural equipment.
Application Challenge:Commonly used traditional float-type level switches experience shorter life spans due to moving parts affected by vibration in a moving vehicle. Installation/orientation issues for correct product placement cause switch to operate poorly or fail to function at all. Float-type sensors used in these applications are subject to reliability and longevity concerns due to moving parts. Detecting falling coolant level requires the loss of liquid to physically move the mechanical float and close the internal reed switch. Additionally, overloading the reed switch will also result in reduced life cycle performance. Installing side mounted float switches can be challenging since precise orientation is important for accurate or even functional operation. |
Application Solution:Gems Sensors’ CAP-300 Capacitive Level Sensor The Gems CAP-300 Level Sensor utilizes solid state electronics without the need for moving parts or reed switches. This makes it more resistant to vibration and eliminates mechanical failure. The sealed IP67 design ensures there is
no fluid intrusion. Gems’ CAP-300 is factory tested and validated to stringent OHV standards to reduce customer validation period and time to market. It endures high shock and vibration testing to Mil-STD-202G, salt spray,
thermal shock, and electrostatic discharge. |
