Degree of protection • Aluminum die-cast or stainless steel housing: IP67, NEMA 4X
• Stainless steel housing for hygienic applications (T17 housing): IP66/IP68 (1.83 m H
2
O for 24 h),
NEMA 4X, NEMA 6P
Shock and vibration resistance 3g / 2 to 150 Hz as per IEC 60 068-2-6
Note!
Care should be taken when using L-form brackets (see wall/pipe 2" brackets in Section ’Accessories’) since this
can cause resonance. Caution: vibrations at the transmitter must not exceed the specified values.
Electromagnetic compatibility
(EMC)
CE Electromagnetic Compatibility Compliance
EMC meets all relevant requirements listed under EN 61326 Series and NAMUR NE21. Details as per
declaration of conformity.
This recommendation is a uniform and practical way of determining whether the devices used in laboratories
and process control are immune to interference with an objective to increase its functional safety.
