P V OUJO H) P MF TN N N N 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. P N N N N % \ .
