Cable specifications for use in areas with severe electrical interference
The Promag 30 measuring equipment fulfils all general requirements for
electromagnetic compatibility (EMC) according to EN 50081 Part 1 and 2 /
EN 50082 Part 1 and 2 when installed in accordance with the NAMUR
recommendations.
Note!
• With the remote-mounted version (FS and FL) the signal and coil cables between
sensor and transmitter must always be screened and earthed at both ends.
This is done at the earth terminals inside the connection housing of sensor and
transmitter (see page 30).
• The cable must be resistant to an ambient temperature of max. +80 °C if the
Promag H is operated at a process temperature of +150 °C.
