Applications: Contact microphone, Dynamic strain gages, Speakers, Switches

　　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. The DT film element produces more than 10 millivolts per microstrain, about 60 dB higher than the voltage output of a foil strain gage. The capacitance is proportional to the area and inversely proportional to the thickness of the element. The DT series sensors are the simplest form of piezo film sensors, used primarily as dynamic strain gages and contact microphones for vibration or impact detection. These are available without any leads for those 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 low temperature solders. DT elements are supplied with a thin urethane coating over the active sensor area; the lead attachment legs are free of the insulating urethane coating.

　　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
