Page 14: Conditions For Safe Operation
Description of the UMC4 transmitter When used in conjunction with the sensor, the UMC4 transmitter measures the mass flow of liquids and gases in pipelines. The transmitter can be mounted on the sensor or remote. The configuration can be carried out by using a built-in or standalone control unit. -
Page 15: Connecting Cables
4.5.3.1 Sensor circuits Compact mounted transmitter UMC4 The sensor circuits in compact mounted assemblies are considered as internal connections and are already wired up and matched by the manufacturer. There is no need to check the intrinsic safety be the operator. -
Page 16: Cable And Conduit Entries
They have to be certified for the type of protection of the transmitter and fit to the cables used. The transmitter series UMC4 for temperature class T4 does not have own ignition sources as long the transmitter runs in smooth operation. Therefore explosion proof certified cable and conduit entries with sealing ring can be used. -
