Prosonic M FMU42 HART Technical data
Hauser 47
Accuracy impacted: high vapor pressures or outgassing from media, e.g.:
• Ethanol
• Acetone
• Ammonia
Please contact the sales organization if the accuracy is affected.
14.5 Environment
14.5.1 Ambient temperature range
–40 to +80 °C (–40 to +176 °F)
The functionality of the LCD display is limited at Tu < –20 °C (–4 °F) and Tu >
60 °C (140 °F)
If operating outdoors in strong sunlight, use a weather protection cover. Can be
ordered as an accessory.
14.5.2 Storage temperature
–40 to +80 °C (–40 to +176 °F)
14.5.3 Climate class
• DIN EN 60068-2-38 (Test Z/AD)
• DIN/IEC 68 T2-30Db
14.5.4 Degree of protection
When housing is closed, tested according to
• IP68, NEMA 6P (24 h at 1.83 m (6 ft) under water)
• IP66, NEMA 4X
When housing is open, tested according to
IP20, NEMA 1 (also degree of protection of the display)
14.5.5 Vibration resistance
DIN EN 60068-2-64/IEC 68-2-64: 20 to 2 000 Hz, 1 (m/s 2 ) 2 /Hz; 3 x 100 min
14.5.6 Electromagnetic compatibility
Electromagnetic compatibility in accordance with all of the relevant requirements outlined
in EN 61326 series and NAMUR Recommendation EMC (NE 21)
More information is provided in the Declaration of Conformity.
• Superimposed communication signal (HART): use a shielded cable
• Analog signal: use a standard installation cable
14.6 Process
14.6.1 Process temperature range
–40 to +80 °C (–40 to +176 °F)
The temperature sensor integrated in the sensor corrects the temperature-dependent
sound time-of-flight.
