2 to 100 Hz at 4g (increased vibration stress)
Shock resistance as per KTA 3505 (section 5.8.4 Shock test)
CE conformity
Electromagnetic compatibility in accordance with all the relevant requirements of the
IEC/EN 61326 series and NAMUR Recommendation EMC (NE21). For details, refer to the
Declaration of Conformity. All tests were passed both with and without ongoing digital
HART® communication. To ensure interference-free HART® communication with EMC
influence, a shielded cable must be used, with the shield connected to ground on both
sides.
Maximum measured error <1% of measuring range.
