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.

　　產(chǎn)品描述:

　　MiniSense100是一款采用懸臂梁結(jié)構(gòu)的低成本振動(dòng)傳感器，端部的質(zhì)量塊使得傳感器在低頻時(shí)產(chǎn)生高靈敏度。其插針結(jié)構(gòu)易于安裝和焊接；水平安裝，垂直安裝及短插針可選。傳感器工作區(qū)域采用自屏蔽結(jié)構(gòu)，防射頻干擾和電磁干擾。柔性PVDF的一端固定，另一端懸空，使其可以經(jīng)受高頻的沖擊載荷。傳感器有良好的線性度和動(dòng)態(tài)測(cè)量范圍，可以用來監(jiān)測(cè)連續(xù)振動(dòng)和沖擊�？赏ㄟ^調(diào)整質(zhì)量塊的重量達(dá)到不同的響應(yīng)頻率和靈敏度（請(qǐng)咨詢MEAS）。MiniSense100是一款采用懸臂梁結(jié)構(gòu)的加速度計(jì)，當(dāng)水平安裝時(shí)，由于慣性的作用，垂直方向的加速度將導(dǎo)致梁的彎曲變形，從而引起薄膜的壓電效應(yīng)，產(chǎn)生的電荷或者電壓信號(hào)通過連接在薄膜上的電極引出。傳感器可以監(jiān)測(cè)連續(xù)的或者脈沖的振動(dòng)或沖擊。對(duì)于諧振頻率以下的激勵(lì)頻率，MiniSense100會(huì)產(chǎn)生很穩(wěn)定的線性輸出，其值為基線對(duì)應(yīng)的靈敏度值。在諧振頻率時(shí)，其靈敏度最大，高頻的沖擊會(huì)引起傳感器的諧振。低頻振動(dòng)的監(jiān)測(cè)很大程度上受到外部電路的影響。
