Structure and mode of operation
The AD105D digital transducer electronics are part of the range of electronics
developed by HBM for static and dynamic weighing processes. They record
the measurement signals of connected sensors with strain gages. The trans
ducer electronics digitally condition the signals and deliver a fully-filtered,
scaled and digitized output signal for direct connection to bus systems or PCs
via the RS‐485 interface or CANopen. The transducer electronics can simply
and quickly be adjusted to the relevant system via various parameters.
The AD105D forms a unit with the transducer and cannot be replaced sepa
rately without recalibrating the system (
SZA/SFA
command). Loads cells or
force transducers, that are temperature compensated and for which the zero
value is set, can be used as transducers.
The PanelX software is available as a free download from the HBM website for
setting all the parameters in full, for realizing dynamic measurement signals,
and for frequency analysis of the dynamic system:
