Safety instructions
6.6.1 IECEx
The approved digital sensors with Memosens technology may be connected via the following measuring
cable
1. CYK10
2. or a structurally identical and in hardware and function identical and Memosens measuring cable
only to the IECEx approved intrinsic safe sensor output circuits of Transmitter Liquiline M CM42 or
alternatively to an IECEx certified, intrinsic safe Memosens sensor output providing the following maxi-
mum values as described below. In particular the effective inner inductivity and capacity of the appro-
ved, intrinsic safe sensor output must not exceed the values given below:
