A seismic mass applies force to a piezoelectric element as the sensor body accelerates. The generated charge is proportional to force and therefore to acceleration within the calibrated operating range.传感器壳体运动时，惯性质量对压电元件施加作用力；在标定工作范围内，产生的电荷与力成正比，从而与加速度成正比。
Charge-output sensors place the piezoelectric element directly at the measurement front end. They suit high temperature, long cable specialization and charge-amplifier systems. IEPE sensors integrate a low-impedance converter and use constant-current excitation, simplifying field wiring and improving immunity to cable noise.电荷输出传感器将压电元件直接接入测量前端，适用于高温、专用长电缆和电荷放大器系统；IEPE 传感器内置信号转换，以恒流方式供电，现场接线更简单，并降低电缆运动噪声的影响。

DS2 uses a shear-mode piezoelectric structure to resolve small, low-frequency vibration with high sensitivity. Low base-strain sensitivity, reduced thermal-transient response and a signal ground isolated from the mounting surface help limit interference from mounting strain, rapid temperature changes and electrically noisy sites. Typical work includes bridge and building response, foundation and site vibration, seismic testing and environmental vibration. All six listed models provide IEPE voltage output for direct connection to constant-current acquisition inputs.DS2 采用剪切式压电结构，在低频微振测量中兼顾较高灵敏度与细微信号分辨能力。较低的基座应变灵敏度、较弱的温度瞬变响应，以及与安装面绝缘的信号地，有助于降低安装基座应变、温度快速变化和现场电气干扰对读数的影响。典型用于桥梁与建筑结构响应、地基与场地微振、地震试验和环境振动测试。页面所列六款均为 IEPE 电压输出，可直接接入恒流供电采集通道。
The stated passband begins at 0.2 Hz, while the shear structure supports high-sensitivity small-signal measurement.标称频带从 0.2 Hz 起，剪切结构适合高灵敏度的小信号测量。
Ground isolation and reduced sensitivity to base strain and thermal transients help suppress common field interference.对地绝缘，并降低基座应变和温度瞬态的影响，减少常见现场干扰。
Suitable for bridges, buildings, foundations, seismic tests and ambient-vibration measurement.适用于桥梁、建筑、地基、地震试验及环境振动测量。

Charge output for specialist conditioning; IEPE for direct constant-current acquisition.电荷输出匹配专业调理，IEPE 直接接入恒流采集通道。
Three orthogonal channels record the complete local acceleration vector at one point. This reduces mounting mismatch between directions and is especially valuable for mode-shape reconstruction, spatial response comparison and compact test articles.三个正交通道在同一测点记录完整局部加速度矢量，减少不同方向独立安装造成的位置与方向误差，适用于振型重构、空间响应对比和紧凑试件。
X/Y/Z phase and amplitude remain directly comparable when the DAQ channels are synchronized.配合同步数采后，X/Y/Z 三方向的相位和幅值可直接比较。
Choose the smaller S family where sensor mass and installation space are tightly constrained.附加质量与安装空间受限时，优先选择小型 S 系列。
The H-family charge sensors extend measurement into hot zones where integrated electronics cannot be placed. The portfolio reaches 485°C for aero-engine, turbine, exhaust, furnace and other high-temperature structural tests.H 系列采用电荷输出，把测量扩展到集成电子电路无法直接工作的高温区域。产品组合最高覆盖 485°C，适用于航空发动机、涡轮、排气、炉体及其他高温结构试验。

Complete these six decisions in order. Do not select a model from range alone: frequency band, signal level, signal chain and installation can change the usable result.按以下顺序完成六个决策。不要只按量程挑型号：频段、信号幅值、信号链和安装都会改变最终可用结果。
Provide the lowest signal of interest and the highest analysis frequency. DS2 starts at 0.2 Hz; choose the 100 mV/g version when the required upper band exceeds 1,500 Hz.提供最低关注频率与最高分析频率。DS2 从 0.2 Hz 起；当所需上限超过 1500 Hz 时，选 100 mV/g 版。
Estimate normal RMS and credible impact peak. Keep overload headroom, then choose the higher sensitivity only if its range and frequency response still contain the event.估算正常 RMS 与可信冲击峰值，先保留过载余量；只有在量程和频响仍覆盖事件时，才选更高灵敏度。
Use single-axis sensing when the dominant direction is known. Use triaxial sensing when vector direction, spatial response or mode-shape comparison matters.主响应方向明确时选单轴；关心矢量方向、空间响应或振型对比时选三轴。
IEPE requires compatible constant-current input and bias range. Charge output requires a charge amplifier; confirm gain, cable and acquisition input together.IEPE 需要匹配的恒流输入与偏置范围；电荷输出需要电荷放大器，增益、电缆与数采输入必须一起确认。
Provide operating temperature, moisture or immersion, EMI, cable route and deployment life. High-temperature points use an applicable H charge model; outdoor points require verified protection.提供工作温度、潮湿或浸水、电磁干扰、线缆路径和部署周期。高温点选适用的 H 电荷型，户外点需核对防护等级。
Confirm mounting surface, thread or adhesive base, allowable sensor mass, connector orientation, cable length and strain relief. T/M/L suffix options are confirmed per exact model.确认安装面、螺纹或胶粘座、允许附加质量、接口方向、电缆长度与应力释放。T/M/L 后缀选项按具体型号确认。
A high-bandwidth sensor cannot correct a flexible mount, poor surface contact, unsecured cable or aliasing in the acquisition chain.高带宽传感器无法弥补柔性安装、接触面不良、电缆未固定或采集链混叠。
Machine a flat, clean seat and tighten to the specified torque. The rigid interface gives the most repeatable high-frequency response and phase.加工平整洁净的安装面，并按规定扭矩紧固。刚性界面可获得最稳定的高频响应与相位重复性。
Degrease and abrade the seat, keep the adhesive layer thin and verify its temperature rating. Added compliance reduces the upper usable frequency.测点需除油并轻度打磨，胶层应薄且满足温度等级。胶层柔度会降低可用频带上限。
Use on clean ferromagnetic steel and secure the cable close to the point. Magnetic bases add mass and compliance, so validate the required bandwidth.适用于洁净铁磁性钢面，并在测点附近固定电缆。磁座会增加质量和柔度，使用前应核验目标频带。
Select the lowest range that safely contains normal response and credible impact peaks without overload.在不发生过载的前提下，选择能够覆盖正常响应与可信冲击峰值的最低量程。
Use a flat clean surface and the specified stud, adhesive or magnetic base; mounting resonance must remain above the analysis band.使用平整洁净表面及规定的螺柱、胶粘或磁座，安装共振应高于分析频带。
Provide strain relief near the sensor and secure the cable away from hot, sharp and high-EMI routes.在传感器附近做应力释放，并避开高温、锐边与强电磁干扰路径固定电缆。
Confirm sensitivity, excitation or charge gain, sample rate, anti-alias filter, polarity and channel orientation before recording.采集前确认灵敏度、恒流激励或电荷增益、采样率、抗混叠滤波、极性与通道方向。
The same acceleration unit serves very different engineering decisions. Sensor range, mounting and acquisition strategy follow the expected dynamics.相同的加速度物理量服务于不同工程判断，量程、安装与采集策略必须跟随目标动力特性。
Traffic, wind, gate and unit-operation response; modal baselines; event-triggered vibration records.交通、风、闸门与机组工况响应，模态基线及事件触发振动记录。
Blade, gearbox and tower vibration under changing speed, load and wind conditions.不同转速、载荷和风况下的叶片、齿轮箱与塔筒振动。
Bogie and car-body response, ride dynamics, track irregularity and impact location.转向架与车体响应、运行平稳性、轨道不平顺与冲击位置识别。
Engine, spindle, tooling and production-quality vibration, including high-temperature measurement points.发动机、主轴、刀具和制造质量振动，包括高温测点。
