Endress+Hauser Micropilot FMR56 - Vibration Resistance; Electromagnetic Compatibility (Emc)

Micropilot FMR56, FMR57
50 Endress+Hauser
Altitude according to
IEC61010-1 Ed.3
• Generally up to 2 000 m (6 600 ft) above MSL.
• Above 2 000 m (6 600 ft) if the following conditions are met:
• Ordering feature 020 "Power supply; Output" = A, B, C, E or G (2-wire versions)
• Supply voltage U < 35 V
• Supply voltage of overvoltage category 1
Degree of protection
• When housing is closed, tested according to:
• IP68, NEMA6P (24 h at 1.83 m under water)
• For plastic housing with see-through lid (display): IP68 (24 h at 1.00 m under water)
This restriction applies if the following options have been selected simultaneously in the product
structure: 030 ("Display/operation") = C ("SD02") or E ("SD03"); 040 ("Housing") = A ("GT19").
• IP66, NEMA4X
• With housing open: IP20, NEMA1
• Display module: IP22, NEMA2
Degree of protection IP68 NEMA6P only applies for M12 PROFIBUS PA plugs if the
PROFIBUS cable is plugged in and is also rated IP68 NEMA6P.

Cleaning the antenna
The antenna may become contaminated depending on the application. Emission and reception of
microwaves can thus be hindered. The level of contamination leading to this error depends on the
medium and on the reflectivity, which is mainly determined by the dielectric constant ε
r
.
If the medium tends to cause contamination and buildup, cleaning on a regular basis is
recommended, e.g. using a purge air connection in the case of FMR57. Care must be taken to ensure
the antenna is not damaged in the process of mechanical or hose-down cleaning. Material
compatibility must be taken into account if cleaning agents are used! The maximum permissible
flange temperatures should not be exceeded.
Electromagnetic
compatibility (EMC)
Electromagnetic compatibility in accordance with all of the relevant requirements outlined in the
EN 61326 series and NAMUR Recommendation EMC (NE 21). For details, refer to the Declaration of
Conformity.

A normal device cable suffices if only the analog signal should be used. Use a shielded cable for
digital communication (HART/ PA/ FF).
Always use a shielded cable for the electronic version "2-wire, 4-20 mA HART + 4-20 mA analog".
Maximum measured error during EMC testing: < 0.5 % of the span. By way of derogation, for
devices with a plastic housing and see-through lid (integrated display SD02 or SD03) the measured
error can be up to 2 % of the span in the event of strong electromagnetic radiation in the 1 to 2 GHz
frequency range.
