Levelflex M FMP40 with HART/4...20 mA Technical data
Hauser 75
Influence of ambient
temperature The measurements are carried out in accordance with EN 61298-3:
• Digital output:
– Average T
K
: 0.6 mm/10 K, max. ±3.5 mm over the entire temperature range -40 °C to +80 °C
2-wire:
• Current output (additional error, in relation to the span of 16 mA):
– Zero point (4 mA)
Average T
K
: 0.032 %/10 K, max. 0.35 % over the entire temperature range -40 °C to +80 °C
– Span (20 mA)
Average T
K
: 0.05 %/10 K, max. 0.5 % over the entire temperature range -40 °C to +80 °C
10.1.4 Operating conditions: environment
Ambient temperature range Ambient temperature at the electronics: -40 °C to +80 °C
The function of the LCD display is restricted at T
A
<-20 °C and T
A
>+60 °C.
A weather protection cover should be used for outdoor operation if the device is exposed to direct
sunlight.
Ambient temperature limits If temperatures above 80 °C are present at the process connection, the permitted ambient
temperature is reduced according to the following diagram (temperature derating):
L00-FMP41xxx-05-00-00-en-001
Storage temperature -40 °C to +80 °C
Climate class DIN EN 60068-2-38 (test Z/AD)
