概述

传感器信号放大器是将传感器输出信号进行精密放大，线路内部进行稳压、恒流供桥、电压电流转换，阻抗适配，线性补偿，温度补偿等，将力学量转换成标准电流、电压信号输出。

美国Transducer Techniques TMO-2集成放大器和信号调理仪功能，用于信号源和读出设备之间的信号调理器件，如衰减器、前置放大器、电荷放大器以及对传感器或放大器进行非线性补偿的电平转换器件。

Transducer TMO-2传感器模块是一款差分放大器/信号调节器，价格好，性价比高。并提供激励，结算和满刻度校准功能。

The TMO-2 Transducer Modules is a complete differential amplifier/signal conditioners with self contained power. The units provide excitation, balance and span adjustment via precision 10 turn pots, and shunt calibration necessary to couple a user supplied bridge type transducer to an indicating instrument. Full scale output is specified at plus or minus 10 VDC. The TMO-2 provides a floating shunt calibration circuit which applies calibration at the transducer, thereby eliminating errors due to line losses. The excitation supply incorporates a Wagner Ground to greatly improve Common Mode Rejection. The factory set bandwidth of the module is narrow to improve stability for applications such as weighing scales. The removal of a single capacitor will increase the frequency response DC to 60K Hz for dynamic data applications.
