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

　　典型應(yīng)用: 接觸式麥克風(fēng)，動態(tài)應(yīng)變計

　　產(chǎn)品描述:

　　SDT系列中的"S"代表"屏蔽"。SDT1壓電薄膜傳感器包含一個與塑膠殼相連的矩形壓電薄膜元件和一根18英寸長的同軸電纜線。薄膜元件上下兩層絲印銀漿，然后對折，形成一個自屏蔽的工作區(qū)域，使得該產(chǎn)品可以應(yīng)用于高電磁干擾環(huán)境。SDT1可用雙面膠，環(huán)氧膠和氰基丙烯酸鹽粘結(jié)劑（超級膠）粘貼到被測物表面。必須注意的是，當(dāng)移去傳感器時，雙面膠有可能將薄膜上的金屬鍍層撕掉。當(dāng)以特定的方式將SDT1粘貼到被測物表面，它可以作為一個性能優(yōu)良的接觸式傳聲器和動態(tài)應(yīng)力計，其輸出信號能直接被示波器或信號分析器接收。

　　特點:

　　自屏蔽傳感區(qū)域
　　SDT1輸出可直接輸入到示波器
　　SDT1輸出可直接輸入到信號分析儀
