DT壓電薄膜傳感器: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. The DT film element produces more than 10 millivolts per microstrain, about 60 dB higher than the voltage output of a foilstraingage.Thecapacitanceisproportional to the area and inversely proportional to the thickness of the element. The DTseriessensors are the simplest form of piezo film sensors, used primarily as dynamicstraingagesandcontact microphones for vibration or impact detection. These are available without anyleadsforthose applications where the customer wants to make his own lead attachment. They can be readily adhered to a surface with double-sided tape or epoxy. Lead attachment can be achieved by compressive clamping, crimps, eyelets, conductive epoxy or lowtemperaturesolders.DTelements are supplied with a thin urethane coating over the active sensor area; the lead attachment legs are free of the insulating urethane coating.

帶引出的DT系列壓電薄膜傳感器：指在薄膜上絲印銀漿作為電極的矩形的壓電薄膜傳感器，它可以做成許多種不同的尺寸和厚度，引出線為28AWG線，長度為12英寸（300mm），由鉚釘將其壓接到薄膜上。DT系列傳感器每微米的應(yīng)變能產(chǎn)生10毫伏的電壓，其電容與工作面積成正比，與薄膜的厚度成反比。DT系列傳感器工作區(qū)域表面的一層防護(hù)層能保護(hù)銀漿不被氧化。
