LVDT差动变压位移传感器-美国TRANS-TEK

产品品牌：美国TRANS-TEK位移传感器

产品名称：直线LVDT差动变压位移传感器

产品型号：LVDT系列直线位移传感器

产品特点：

LVDT 意思为Linear Variable Differential Transformer(差动变压位移传感器). 基本元件由一个铁芯和两个线圈组成. 通过一次线圈与二次线圈弱电磁耦合，使得铁芯的位移变化量与输出电压(电流)变化量呈精密线性关系。

Series 200型号：

The Series 200 DC-DC LVDTs are precision Linear Variable Differential Transformers packaged with a solid state oscillator and a phase sensitive demodulator. The transducer is designed to work with DC voltages, and has excellent linearity, infinite resolution, and high sensitivity. Input and output circuits are electrically isolated from each other and from the coil assembly housing, making them usable directly in floating or ground return systems. DC indicators, recorders, and control systems can usually be driven directly by the large DC output. The core, when displaced axially within the coil assembly, produces a voltage change in the output directly proportional to the displacement.

系列200 DC-DC LVDTs是一种精密线性变差动变压器，配有固态振荡器和相敏解调器。该换能器设计用于直流电压工作，具有良好的线性度、无限分辨率和高灵敏度。输入和输出电路相互隔离，并从线圈组装外壳，使他们可以直接用于浮动或地面返回系统。直流指示器、记录器和控制系统通常可以由大的直流输出直接驱动。当铁芯在线圈总成内轴向位移时，其输出电压的变化与位移成正比。

SPECIFICATIONS - ELECTRICAL

Notes:

1. Polarity of excitation must be observed for proper function. Reversal will not damage the unit.

2. Load Impedance of 50 KOhms minimum required for proper operation.

3. Output polarity will be positive on one side of null, negative on the other side of null.

4. Blue lead is more positive with respect to the Green lead when the core is moved to- ward the lead end.

• 注:
• 1. 激发的极性必须观察到适当的功能。反转不会损坏单位。
• 2. 负载阻抗为50 KOhms最小要求为正确的操作。
• 3.输出极性在零点的一边为正，在零点的另一边为负。
• 4. 当磁芯向铅端移动时，蓝色铅对绿色铅的正电荷更大。

CORE OPTIONS

* Model numbers ending with a “_” have multiple core options. All standard units will end with a 0 indicating a core assembly. This core assembly consists of a core brazed to an extension rod that terminates in 1-72 UNF-2A threads. If an option is not selected, option 0 will be provided. Option 1 indicates a core assembly with a smaller core. Core options 2 and 3 provide a threaded core only. A separate extension rod can be used to connect the core to the moving object.
