F173 Safe Area / Intrinsically Safe Level Monitor
Brand: Precision Digital Corporation
The F173 is a versatile level indicator featuring linearization and continuous level monitoring.
In addition to the average Span, fifteen linearization points can be entered to compensate for the tank shape.
The unit will interpolate between these points to increase accuracy. This linearization affects all displayed information as well as the alarm and analog outputs.
With the level monitoring feature, two low and two high level alarm values can be set. If desired, an ignore function can be set up to allow for an incorrect level for a certain period of time. Up to five outputs are available to transmit alarm conditions and actual level.
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.
