A.1.2 Environment
Vibration resistance
No effect when tested per the requirements of IEC60770-1
(1999): High Vibration Level - field or pipeline (10-60 Hz
0.21 mm displacement peak amplitude / 60-2000 Hz 3g).
Electromagnetic compatibility
Meets CE 61326:2012 and NE21:2012 if installed in
metallic vessels or still pipes.
For optimal single lead probe performance in
non-metallic tanks, the probe must be mounted with a
metal flange, or screwed in to a metal sheet (d > 14
in./350 mm) if a threaded version is used. See
in non-metallic tanks and open-air applications" on
page 19 for more information.
