MODEL TMO-2A

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.
