Industries: General Industry, Consumer Goods
Description: The Piezo Film Lab Amplifier is a versatile preamplifier for use with Piezoelectric sensors. The electric signal from the piezo film is generated within the electrodes of a capacitor. It is important to arrange an input that controls the rate of charge leakage appropriately for the application. Simply connecting a piezo film element to the input of an oscilloscope will usually create a high-pass filter that removes any low frequency content of the original piezo signal, and this can lead to disappointment or incorrect evaluation of the material's true potential. This has led MEAS to develop a new low-cost Piezo Film Lab Amp, specifically aimed at developers and engineers exploring the material. Both first-time users and seasoned professionals will benefit from the wide range of sensitivity adjustment in either voltage or charge modes, and the functionality of the high- and low-pass filters.

產品描述:
壓電薄膜實驗室放大器是一種適用于壓電傳感器的萬能前置放大器。壓電薄膜的電信號由電容的電極產生。準備一個輸入源來合理控制電荷的流失比率是非常重要的。簡單地連接壓電薄膜元件到示波器的輸入端通常會產生一個高通濾波器，將原始壓電信號的低頻內容全部濾除，這可能會導致材料的錯誤評估和使用。 因此MEAS研發了一種新的低成本壓電薄膜實驗室放大器，為研發工程師探索研究材料提供方便。放大器電壓和電荷模式下的寬靈敏度調節范圍，和高/低通濾波器功能對初次使用者和經驗豐富的專業人士都有幫助。
