Operating conditions: Environment
Ambient temperature range
Ambient temperature for electronics: -40 °C to +80 °C
The functionality of the LCD display may be limited for temperatures 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 the temperature (T
2
) at the process connection is above 80 °C, the permitted ambient
temperature (T
1
) decreases as per the following diagram (temperature derating):
L00-FMP43xxx-05-00-00-en-002
Storage temperature
-20 °C to +80 °C (-4 °F to +176 °F)
Climate class
DIN EN 60068-2-38 (test Z/AD)
Degree of protection
• With closed housing tested according to
– Housing F12/T12: IP68, NEMA6P (24 h at 1.83 m under water)
– Housing F23: IP69K in combination with cable entries M20 G ½ and NPT ½
– IP66, NEMA4X
• With open housing: IP20, NEMA1 (also ingress protection of the display)
Caution!
Degree of protection IP68 NEMA6P applies for M12 PROFIBUS PA connectors only when the
PROFIBUS cable is plugged in.
Vibration resistance
DIN EN 60068-2-64 / IEC 68-2-64: 20 to 2000 Hz, 1 (m/s

Cleaning the probe
Depending on the application, soiling or buildup can accumulate on the probe. A thin, even layer
only influences measurement slightly. Thick layers can dampen the signal and then reduce the
measuring range. Heavy, uneven buildup, adhesion through crystallization, for example, can lead
to incorrect measurement. In such instances, we recommend you use a non-contact measuring
principle, or check the probe regularly for soiling.
