The SEA 1811-BSS 1811 VSM 422 Tank Sender Level is a versatile and advanced level sensor designed for use in marine applications. This level sensor is part of the Vespera Marine VSM (Variable Specific Measurement) series, which offers high accuracy and reliability for monitoring the fuel level in marine tanks.
The 1811-BSS model is specifically designed for use with diesel and water/alcohol glycol coolant tanks. It features a robust, marine-grade stainless steel construction that is resistant to corrosion and the harsh environmental conditions typically found at sea. The sensor's housing is made from 316L stainless steel, ensuring a long service life and maintaining the integrity of the sensor even in the most demanding marine environments.
The sensor utilizes a capacitive measurement principle, which provides accurate and continuous level measurements. The advanced design of the sensor allows for level measurement even in tanks with complex geometries or non-uniform surfaces. The sensor can be easily installed in tanks with internal diameters ranging from 0.25 to 2.5 meters (10 to 100 inches).
The SEA 1811-BSS 1811 VSM 422 Tank Sender Level is designed to be interfaced with the Vespera VMS (Vessel Monitoring System) or other marine monitoring systems. It can be connected to the system via NMEA 2000 or J1939 protocols, enabling easy integration into existing monitoring and control systems. This sensor also features a built-in self-diagnostic function, which allows for quick identification of any issues and ensures reliable operation.
The sensor's compact design and rugged construction make it an ideal choice for marine applications where accurate and reliable level measurement is essential. Its ability to interface with various marine monitoring systems and its robust design make it a valuable addition to any marine vessel's onboard equipment. With its high accuracy, reliability, and easy installation, the SEA 1811-BSS 1811 VSM 422 Tank Sender Level is an excellent investment for ensuring the efficient and safe operation of marine tanks.
