　　Description: 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 urethane coating over the active electrode area to prevent oxidation to the top surface of the silver ink.

　　Features:

　　Available in a variety of different sizes and thicknesses
　　DT film element produces more than 10 millivolts per micro-strain

　　典型应用: 接触式麦克风，动态应变计，扬声器，开关

　　产品描述:

　　DT系列压电薄膜传感器元件是银墨丝印电极的矩形压电薄膜元件，有很多不同的尺寸和厚度可供选择。DT系列薄膜元件每微米的应变产生超过10毫伏的电压信号，比箔金属应变片的电压输出高大约60dB。电容与元件面积成正比例，与元件厚度成反比例。DT系列传感器是压电薄膜传感器的最简单形式，主要用于振动和冲击检测的动态应变计和接触式麦克风。如果客户需要自己安装引线，MEAS也可以提供无引脚产品。可用双面胶带或环氧树脂将传感器粘贴在被测物体表面上。引线可用压钳、压接、打孔、导电环氧树脂、低温焊接的方式连接。DT元件的动态传感区域有一层很薄的聚氨酯涂层，而引脚的部分则没有绝缘的聚氨酯涂层。

　　特点:

　　多种尺寸、厚度可选
　　每个微应变产生超过10毫伏的电压信号
　　最简单的压电薄膜传感器
　　可用双面胶带或环氧树脂轻松安装
