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 DPM-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。
The voltage-to-frequency microprocessor makes Transducer Technique's 4-digit panel mount meters the ideal solution for meeting the measurement, display and control requirements of noisy industrial applications, OEMs and system designers. Model DPM-2 accepts any full bridge transducer. Balance and span can be selected via the front keypad, thus allowing the display to read directly in engineering units. Front panel max and tare functions are ideal for industrial weighing applications. Isolated adjustable 9-11VDC excitation with remote sense and 90 mA drive eliminates the need for external power supplies. Rear screw terminals connectors are included.
