8.1 General information
8.1.1 Shielding design
Sources of interference can cause electromagnetic fields which can induce in
terference voltages inductively or capacitively 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 interference
immunity (EMI) and the permissible electromagnetic interference emissions
(EME), has become increasingly 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
transducer housing and is routed via the conductive plug to the amplifier hous
ing. The effect of electromagnetic interference is significantly reduced by these
measures.
