產(chǎn)品簡介
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(nèi)部進行穩(wěn)壓、恒流供橋、電壓電流轉(zhuǎn)換，阻抗適配，線性補償，溫度補償?shù)龋瑢⒘W(xué)量轉(zhuǎn)換成標(biāo)準(zhǔn)電流、電壓信號輸出。
美國Transducer Techniques TMO-2A集成放大器和信號調(diào)理儀功能，用于信號源和讀出設(shè)備之間的信號調(diào)理器件，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?shù)碾娖睫D(zhuǎn)換器件。
Transducer TMO-2A傳感器模塊是一款差分放大器/信號調(diào)節(jié)器，價格好，性價比高。并提供激勵，結(jié)算和滿刻度校準(zhǔn)功能。
The TMO-2A Transducer Modules is a complete differential amplifier/signal conditioners with self contained power. The unit 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. Zero to full scale output is specified at 4-20 mA. The TMO-2A 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. The removal of a single capacitor will increase the frequency response DC to 60K Hz for dynamic data applications.
