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.

描述
該MiniSense 100是通過質量加載到提供在低頻高靈敏度的低成本懸臂式振動傳感器。引腳設計,易於安裝和焊接的都是。提供水平和垂直安裝選項。有源傳感器面積為屏蔽改善RFI / EMI抑制。堅固,靈活的PVDF傳感元件承受高衝擊負荷。傳感器具有優異的線性度和動態範圍,並且可以用於檢測任一連續的振動或衝擊。大眾可能會被修改,以獲得替代的頻率響應和靈敏度選擇(諮詢工廠)。
所述MiniSense 100用作懸臂梁加速度計。當光束被水平安裝,在垂直平面內的加速度會創建彎曲的梁,由於質量的在梁的尖端的慣性。菌株在光束創建的壓電響應,其可以作為在傳感器的電極的電荷或電壓輸出來檢測。該傳感器可被用來檢測連續的或脈衝的振動或衝擊。用於傳感器的共振頻率下激勵頻率,該裝置產生通過“基線”靈敏度管轄的線性輸出。在諧振的靈敏度是顯著高。含高頻成分的影響將激發的諧振器為頻率,如上面的(MiniSense 100響應於單個半正弦脈衝在100赫茲,振幅0.9克)的曲線圖。傳感器,以檢測低頻運動的能力強烈地受到外部電路的影響。
應用:
