DT Series Elements with Lead Attachment Piezoelectric film sensor AC Coupled Silver Ink Electrodes Protective Coating over Electrodes Lead Wires Attached with Rivets The DT Series of Piezo film sensors 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.
