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 LCA-RTC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,两级如衰减器、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 LCA-RTC成本低,专用于单电桥式称重传感器或者扭矩传感器的信号调节。灵敏度范围:0.5 mV/V to 10 mV/V, 频宽100 Hz to 30kHz,放大输出信号有:0 to ±5V, 0 to ±10V, 0-16 mA, 0-20 mA or 4-20 mA.

The LCA-RTC Module provide low-cost, dedicated signal conditioning for a single bridge type load cell or torque sensor. Model LCA-RTC comes with removable screw-clamp terminal connectors, which accept wires without soldering. On- board jumper selections include sensitivities from 0.5 mV/V to 10 mV/V, bandwidths from 100Hz to 30 kHz, and amplified outputs of 0 to ±5V, 0 to ±10V, 0-16 mA, 0-20 mA or 4-20 mA. Zero and span adjustments are via precision 25-turn low-tempco metal film potentiometers. The units can be operated next to the sensor with 4-wire hookup or at distances up to 1 km (3300 feet) with 6-wire hookup. An onboard 87.325 kΩ resistor allows easy shunt calibration at the push of a button. Provision is also made for a userfurnished calibration resistor. Power requirements are 11.8 to 26V DC with load currents from 10 to 60 mA, the latter applying when the unit provides 10V DC excitation to a 350 ohm load cell and delivers a 20 mA analog output.
