傳感器信號放大器是將傳感器輸出信號進行精密放大，線路內部進行穩壓、恒流供橋、電壓電流轉換，阻抗適配，線性補償，溫度補償等，將力學量轉換成標準電流、電壓信號輸出。

美國Transducer Techniques LCA-9PC集成放大器和信號調理儀功能，用于信號源和讀出設備之間的信號調理器件，兩級如衰減器、前置放大器、電荷放大器以及對傳感器或放大器進行非線性補償的電平轉換器件。

Transducer LCA-9PC成本低，專用于單電橋式稱重傳感器或者扭矩傳感器的信號調節。靈敏度范圍：0.5 mV/V to 10 mV/V, 頻寬100 Hz to 30kHz，放大輸出信號有：0 to ±5V, 0 to ±10V, 0-16 mA, 0-20 mA or 4-20 mA.

The LCA-9PC Module provides low-cost, dedicated signal conditioning for a single bridge type load cell or torque sensor. Model LCA-9PC comes with DB9 male and female connectors, which require soldering to user-furnished mating female or male wire connectors. On- board jumper selections include sensitivities from 0.5 mV/V to 10 mV/V, bandwidths from 100 Hz to 30kHz, 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 user-furnished 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 10VDC excitation to a 350 ohm load cell and delivers a 20 mA analog output
