areas
The inductive Sensor-Cable-Connecting System Memosens, which consists of:
• IECEx / ATEX approved sensors with Memosens technology
• measuring cable CYK10-G**a, a = 1, 2
• measuring cable CYK10-I**a, a = 1, 2
is approved for measuring application in explosive atmospheres according to
a) IECEx Type Approval BVS 11. 0052 X
b) EC Type Approval BVS 04 ATEX E 121 X with supplements.
