Differing from this, the following measuring error is present for thin interfaces
(only for electronic version "K" interface measurement):
L00-FMP4xIxx-05-00-00-en-001
Resolution • Digital: 1 mm
• Analog: 0.03 % of the measuring range
Reaction time The reaction time depends on the configuration.
Shortest time:
• 2-wire electronics: 1 s
• 4-wire electronics: 0.7 s
Influence of ambient
temperature
The measurements are carried out in accordance with EN 61298-3:
• Digital output (HART, PROFIBUS PA, FOUNDATION Fieldbus):
– Average T
K
: 0.6 mm/10 K, max. ±3.5 mm over the entire temperature range -40 °C to +80 °C.
2-wire:
