HBM template: Inductive Displacement Transducer
The physical unit is defined when the transducer manufacturer (or user)
creates the template. At the time of creating the template it is also necessary
to choose between the options ”Full Precision”, ”mV/V” and ” µ V/V” for the
accuracy of the characteristic transducer curve mapped in TEDS. HBM
always opts for ”Full Precision” here, in order to be able to use full digital
resolution. This choice is also recommended to operators who program the
TEDS memory themselves.

The difference between these val-
ues is the sensitivity according to
Maximum Electrical
Value
80.000m V/V CAL
ues is the sensitivity according to
the HBM data sheet, the HBM test
certificate or from calibration.
Mapping Method Linear This entry cannot be changed.
Bridge type Full The bridge type.
The following values are available
for selection: ”Quarter” for quarter
bridge, ”Half” for half bridge, ”Full”
for full bridge. Some HBM transduc-
ers can be connected as half
bridges or full bridges according to
choice.
