Applications: Contact microphone, Dynamic strain gage

　　Description: The ‘S’ in SDT Series stands for ‘Shielded Sensor’. SDT1 piezo film sensors consist of a rectangular element of piezo film together with a molded plastic housing and 18” of coaxial cable. The film element, screen printed with silver ink, is folded over on itself, given a self-shielding of the transducer area. This is important in applications in high EMI environments. The SDT1 can be adhered to other surfaces using double sided adhesives, epoxy or cyanoacrylate (super-glue). Care should be taken if the sensor is to be removed, as the double-side adhesive can peel the metallization from the film. When adhered to a surface in this manner, the SDT1 is an excellent contact microphone or dynamic strain gage. The output from the SDT1 can input directly to an oscilloscope or a signal analyzer.

　　Features:

　　Self-shielding of the transducer area
　　Output from the SDT1 can input directly to an oscilloscope
　　Output from the SDT1 can input directly to a signal analyzer

　　典型应用: 接触式麦克风，动态应变计

　　产品描述:

　　SDT系列中的"S"代表"屏蔽"。SDT1压电薄膜传感器包含一个与塑胶壳相连的矩形压电薄膜元件和一根18英寸长的同轴电缆线。薄膜元件上下两层丝印银浆，然后对折，形成一个自屏蔽的工作区域，使得该产品可以应用于高电磁干扰环境。SDT1可用双面胶，环氧胶和氰基丙烯酸盐粘结剂（超级胶）粘贴到被测物表面。必须注意的是，当移去传感器时，双面胶有可能将薄膜上的金属镀层撕掉。当以特定的方式将SDT1粘贴到被测物表面，它可以作为一个性能优良的接触式传声器和动态应力计，其输出信号能直接被示波器或信号分析器接收。

　　特点:

　　自屏蔽传感区域
　　SDT1输出可直接输入到示波器
　　SDT1输出可直接输入到信号分析仪
