APPLICATIONS
DT Series Elements
The DT Series
elements are rectangular elements of Piezo
film with silver ink screen printed electrodes.
They are available in a variety of different
sizes and thicknesses. Lead attachment is
accomplished using a riveted lug going to
12” (300 mm) of 28 AWG wire.
The DT film element produces more then 10
millivolts per micro-strain. The capacitance
is proportional to the area and inversely
proportional to the thickness of the element.
The DT elements are supplied with a thin
protective coating over the active electrode
area to prevent oxidation to the top surface
of the silver ink.
