来源:赛斯维传感器网 发表于 2014/7/3

 

 

  Applications: Low Frequency Dynamic Strain, Pyroelectric Signals, Audio-band and Acoustic Signals, Machine Vibration, Piezo Cable and Traffic Sensor Interface

  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.

  典型应用: 低频动态应变,热电信号,音频波段及声信号,机械振动,压电电缆及交通传感器接口

  行业: 工业控制, 消费电子和家用电器

  产品描述:

  压电薄膜实验室放大器是一种适用于压电传感器的万能前置放大器。压电薄膜的电信号由电容的电极产生。准备一个输入源来合理控制电荷的流失比率是非常重要的。简单地连接压电薄膜元件到示波器的输入端通常会产生一个高通滤波器,将原始压电信号的低频内容全部滤除,这可能会导致材料的错误评估和使用。 因此MEAS研发了一种新的低成本压电薄膜实验室放大器,为研发工程师探索研究材料提供方便。放大器电压和电荷模式下的宽灵敏度调节范围,和高/低通滤波器功能对初次使用者和经验丰富的专业人士都有帮助。

  特点:

  电荷或电压模式操作
  BNC输入和输出
  电荷模式下灵敏度范围:0.01~1000mV/pC
  输入电阻:1M ~ 1G,电压模式增益:-40 ~ 40dB
  多极点,低通/高通滤波器,-3dB频率范围:0.1Hz ~ 100kHz
  内置电池(2×9V)或24VDC外部电源供电
  宽动态范围 
  动态HP和LP滤波器
