Description
The LPD450F allows you to display
process variables in any required unit of
measurement.
The display is loop powered by the 420mA current loop with no external supply
required.
The 20mm display characters make the
process values easily visible at a distance
even in direct sunlight.
Traffolyte Labels are available as an option
for both engineering units and tag numbers.
As an option, the unit can be supplied with
a pipe mounting bracket suitable for both
horizontal and vertical pipes.
