Features

• Compact form factor enables installation in applications with space constraints, such as small tanks and vessels
• G1″ process connection is compatible with full suite of hygienic process connection adapters
• M12 electrical connector allows for simple installation and start-up
• 4-20 mA output and IO-link deliver ease of integration to existing or new systems
• Configurable switch output for indication of abnormal level conditions
• Reliable level values up to the top of the tank with no dead zone – ideal for small tanks
• The sensor has been designed to withstand tank cleaning processes (CIP and SIP) as well as external washdowns (IP69K rated)
• Stainless steel housing which has minimal crevices and a drip-off seal design that is insensitive to condensation and build-up
• The 80 GHz and FMCW technology provide a more focused beam angle to avoid and optimize the handling of internal obstructions
• Fast Sweep Technology provides continuous surface tracking for greater measurement reliability and accuracy, especially in fast filling applications
• Maintenance free solution unaffected by process conditions such as density, viscosity, temperature, pressure and pH
• Unique CIP algorithm to detect cleaning procedures automatically
