The F073 is a versatile level indicator with continuous level monitoring feature. It offers the ability to set one low level and one high level alarm value. If desired, an ignore function can be set up to allow for an incorrect level for a certain period of time. The configuration of the Span, off-set and number of decimals is done through software functions, without any sensitive DIP-switches or trimmers. The display shows the actual level, height or percentage, alarm values, alarm messages and status. On-screen engineering units are easily configured from a comprehensive selection.
Advantages
Robust IP66, IP67 (NEMA Type4X) field enclosure. It is so rugged, you can even stand on it!
