Bailey BCN7421515120 3" Flanged Tank Mount Level Transmitter

The Bailey BCN7421515120 is a robust differential pressure level transmitter designed for accurate tank level measurement in industrial applications, such as chemical processing, water treatment, and oil & gas. Manufactured by Bailey Controls (now part of ABB), this model utilizes differential pressure technology to measure liquid levels by detecting pressure differences, converting them into a standard 4-20mA output signal for easy integration with control systems. Key features include a 3" flanged connection for secure tank mounting, a measurement range up to 200 inches of water column (equivalent to approximately 5 meters of water head), and a maximum working pressure of 1369 kPa (200 psi). It offers high reliability in harsh environments, with corrosion-resistant materials and explosion-proof housing suitable for hazardous areas. Advantages over similar products include its proven durability from the 1990s era design, compatibility with legacy systems, and straightforward calibration. However, as an older model, it may lack modern digital interfaces like HART protocol found in newer transmitters, potentially requiring additional converters for advanced diagnostics. Benefits include cost-effective level monitoring with minimal maintenance, while drawbacks could involve limited scalability for very high-pressure applications compared to contemporary models. Ideal for continuous level detection in storage tanks, it ensures precise control and safety in fluid management processes.
