8.1 General information
8.1.1 Shielding design
Sources of interference can cause electromagnetic fields
which can induce interference voltages inductively or ca
pacitively via the connection cable and device housing in
the measurement circuit and therefore interfere with the
device function. It must be ensured that the devices used
in the system also do not transmit any electromagnetic
interference. Electromagnetic compatibility (EMC), which
encompasses both the required electromagnetic interfer
ence immunity (EMI) and the permissible electromag
netic interference emissions (EME), has become increas
ingly important over the years.
The HBM Greenline shielding design
The measuring chain is completely enclosed by a
Faraday cage by appropriate routing of the cable shield.
The cable shield is extensively connected with the trans
ducer housing and is routed via the conductive plug to
the amplifier housing. The effect of electromagnetic inter
ference is significantly reduced by these measures.
