德国P+F倍加福超声波对射式传感器

德国P+F倍加福超声波对射式传感器详情说明：

TDA2030功率放大器即产生交流激磁功率电源，通过能源环形变压器T1从静止的初级线圈传递至旋转的次级线圈，得到的交流电源通过轴上的整流滤波电路得到±5V的直流电源，该电源做运算放大器AD822的工作电源；由基准电源AD589与双运放AD822组成的高精度稳压电源产生±4.5V的精密直流电源，该电源既作为电桥电源，又作为放大器及V/F转换器的工作电源。当弹性轴受扭时，应变桥检测得到的mV级的应变信号通过仪表放大器AD620放大成1.5v±1v的强信号，再通过V/F转换器LM131变换成频率信号，通过信号环形变压器T2从旋转的初级线圈传递至静止次级线圈，再经过外壳上的信号电路滤波、整形即可得到与弹性轴承受的扭矩成正比的频率信号，该信号为TTL电平，既可提供给二次仪表或频率计显示也可直接送计算机。由于该旋转变压器动--静环之间只有零点几毫米的间隙，加之感应器轴上部分都密封在金属外壳之内，形成有效的屏蔽，因此很强的抗干扰能力。
倍加福超声波对射式传感器把某种形式的能量转换成另种形式的能量。有两类：有源的和无源的。有源感应器能将种能量形式直接转变成另种，不需要外接的能源或激励源。
无源感应器不能直接转换能量形式，但它能控制从另输入端输入的能量或激励能，感应器承担将某个对象或过程的特定特性转换成数量的工作。其“对象”可以是固体、液体或气体，而它们的状态可以是静态的，也可以是动态(即过程)的。对象特性被转换量化后可以通过多种方式检测。对象的特性可以是物理性质的，也可以是化学性质的。按照其工作原理，它将对象特性或状态参数转换成可测定的电学量，然后将此电信号分离出来，送入感应器系统加以评测或标示。
其zui简单的形式是，传感器作为个模拟换能器，直接返回个电压。在已知磁场下，其距霍尔盘的距离是可以被设定的。使用多组传感器，磁铁的相关位置可被推断出。
通过导体的电流会产生个随电流变化的磁场，并且霍尔效应传感器可以在不干扰电流情况下而测量电流。典型的为，将其和绕组磁芯或在被测导体旁的永磁体合成体。
通常，霍尔效应传感器和电路相连，从而允许设备以数字（开/关）模式操作，在这种情况下可以被称为开关[5]。工业中常见的设备，例如气缸，也被用于日常设备中；如些打印机使用他们来监测缺纸和敞盖的情况。当键盘被要求高性时，也被应用于键盘中。
霍尔效应传感器通常被用于计量车轮和轴的速度，例如在内燃机点火定时（正时）或转速表上。其在无刷直流电动机的使用，用来检测永磁铁的位置。图示中的轮子，带有两个等距的磁铁，传感器上的电压在个周期内将两次达到峰值。此设置通常被用来校准磁盘驱动的速率。
