Applications: Detect either continuous or impulsive vibration or impacts

　　Industries: Engine and Vehicle, Medical, General Industry, Consumer Goods

　　Description: The MiniSense 100 is a low cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. Pins are designed for easy installation and are solderable. Horizontal and vertical mounting options are offered. The active sensor area is shielded for improved RFI/EMI rejection. Rugged, flexible PVDF sensing element withstands high shock overload. Sensor has excellent linearity and dynamic range, and may be used for detecting either continuous vibration or impacts. The mass may be modified to obtain alternative frequency response and sensitivity selection (consult factory). The MiniSense 100 acts as a cantilever-beam accelerometer. When the beam is mounted horizontally, acceleration in the vertical plane creates bending in the beam, due to the inertia of the mass at the tip of the beam. Strain in the beam creates a piezoelectric response, which may be detected as a charge or voltage output across the electrodes of the sensor. The sensor may be used to detect either continuous or impulsive vibration or impacts. For excitation frequencies below the resonant frequency of the sensor, the device produces a linear output governed by the "baseline" sensitivity. The sensitivity at resonance is significantly higher. Impacts containing high frequency components will excite the resonance fre-quency, as shown in the plot above (response of MiniSense 100 to a single half-sine impulse at 100 Hz, of amplitude 0.9 g). The ability of the sensor to detect low frequency motion is strongly influenced by the external electrical circuit.

　　产品描述:

　　MiniSense100是一款采用悬臂梁结构的低成本振动传感器，端部的质量块使得传感器在低频时产生高灵敏度。其插针结构易于安装和焊接；水平安装，垂直安装及短插针可选。传感器工作区域采用自屏蔽结构，防射频干扰和电磁干扰。柔性PVDF的一端固定，另一端悬空，使其可以经受高频的冲击载荷。传感器有良好的线性度和动态测量范围，可以用来监测连续振动和冲击。可通过调整质量块的重量达到不同的响应频率和灵敏度（请咨询MEAS）。MiniSense100是一款采用悬臂梁结构的加速度计，当水平安装时，由于惯性的作用，垂直方向的加速度将导致梁的弯曲变形，从而引起薄膜的压电效应，产生的电荷或者电压信号通过连接在薄膜上的电极引出。传感器可以监测连续的或者脉冲的振动或冲击。对于谐振频率以下的激励频率，MiniSense100会产生很稳定的线性输出，其值为基线对应的灵敏度值。在谐振频率时，其灵敏度最大，高频的冲击会引起传感器的谐振。低频振动的监测很大程度上受到外部电路的影响。
