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.

　　產(chǎn)品描述:

　　DT系列壓電薄膜傳感器元件是銀墨絲印電極的矩形壓電薄膜元件，有很多不同的尺寸和厚度可供選擇。DT系列薄膜元件每微米的應(yīng)變產(chǎn)生超過10毫伏的電壓信號，比箔金屬應(yīng)變片的電壓輸出高大約60dB。電容與元件面積成正比例，與元件厚度成反比例。DT系列傳感器是壓電薄膜傳感器的最簡單形式，主要用于振動和沖擊檢測的動態(tài)應(yīng)變計和接觸式麥克風(fēng)。如果客戶需要自己安裝引線，MEAS也可以提供無引腳產(chǎn)品。可用雙面膠帶或環(huán)氧樹脂將傳感器粘貼在被測物體表面上。引線可用壓鉗、壓接、打孔、導(dǎo)電環(huán)氧樹脂、低溫焊接的方式連接。DT元件的動態(tài)傳感區(qū)域有一層很薄的聚氨酯涂層，而引腳的部分則沒有絕緣的聚氨酯涂層。

　　特點:

　　多種尺寸、厚度可選
　　每個微應(yīng)變產(chǎn)生超過10毫伏的電壓信號
　　最簡單的壓電薄膜傳感器
　　可用雙面膠帶或環(huán)氧樹脂輕松安裝
