DIN EN 60068-2-38 (test Z/AD)

Degree of protection

Up to 2 000 m (6 600 ft) above MSL.

Can be expanded to 3 or HAW569.

000 m (9 800 ft) above MSL by application of an overvoltage protection, e.g. HAW562

• With closed housing tested according to:

– IP68, NEMA6P (24 h at 1.83 m under water surface)

– For plastic housing with transparent cover (display module): IP68 (24 h at 1.00 m under water surface)

4)

– IP66, NEMA4X

• With open housing: IP20, NEMA1 (also ingress protection of the display)

Degree of protection IP68 NEMA6P applies for M12 PROFIBUS PA plugs only when the PROFIBUS cable is plugged in and is also rated IP68 NEMA6P.

Vibration resistance

Cleaning the probe

DIN EN 60068-2-64 / IEC 68-2-64: 20 to 2 000 Hz, 1 (m/s 2 ) 2 /Hz

Depending on the application, contamination 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.

Severe, uneven buildup, adhesion e.g. through crystallization, can lead to incorrect measurement. In this case, we recommend that you use a non-contact measuring principle, or check the probe regularly for soiling.

Electromagnetic compatibility

(EMC)

Electromagnetic compatibility to EN 61326 and NAMUR Recommendation EMC (NE21). Details are provided in the Declaration of Conformity

5)

. A standard installation cable is sufficient if only the analog signal is used.

Use a shielded cable when working with a superimposed communications signal (HART).

Maximum measured error: < 0.5 % of the span.

When installing the probes in metal and concrete tanks and when using a coax probe:

• Interference emission to EN 61326 - x series, electrical equipment Class B.

• Interference immunity to EN 61326 - x series, requirements for industrial areas and NAMUR

Recommendation NE 21 (EMC)

The measured value can be affected by strong electromagnetic fields when installing rod and rope probes without a shielding/metallic wall, e.g. in plastic and wooden silos.

• Interference emission to EN 61326 - x series, electrical equipment Class A.

• Interference Immunity: the measured value can be affected by strong electromagnetic fields.

Process temperature range

Materials in contact with process

This range may be reduced by the selected process connection. The pressure rating (PN) specified on the flanges refers to a reference temperature of 20 °C, for ASME flanges 100 °F. Pay attention to pressuretemperature dependencies.

Please refer to the following standards for the pressure values permitted for higher temperatures:

• EN 1092-1: 2001 Tab. 18

With regard to their temperature stability properties, the materials 1.4435 and 1.4404 are grouped under 13E0 in EN 1092-1 Tab. 18. The chemical composition of the two materials can be identical.

• ASME B 16.5a - 1998 Tab. 2-2.2 F316
