¡¡¡¡1¡¢Dedicated cable used for remote type electromagnetic flowmeter, the shorter, the better
¡¡¡¡2¡¢YZ rubber conduit used for excitation cable, its length is the same as signal cable
¡¡¡¡3¡¢Signal cable must be isolated with other power cable, do not laid in one conduit or parallel and twisted, should be in the thin wall steel conduit independently
¡¡¡¡4¡¢Keep the signal cable and excitation cable as short as possible, do not wind the exceeding part, which should be cut off and re-weld connector, bend the cable into U shape at the electrical port of the transducer to prevent raining into transducer |
