The CD12 is a portable, high-gain Carrier Demodulator, used to provide transducer excitation, and to amplify and demodulate the output of variable-reluctance transducers, strain gages, linear and rotary variable differential transformers, and potentiometric transducers. It operates with full or half-bridge transducers, delivering a 10 Vdc output for inputs ranging from 0.9 to 75 mV/V.
Ideal for use in R & D labs, medical laboratories, and field use. The compact instrument accurately displays the transducer signal on its integral 5-inch analog meter, as well as providing two analog outputs, one of which is controlled by the suppression circuitry. A suppression circuit is incorporated into the CD12 to critically observe signal deviations around a reference level. Input signals can be suppressed from 0 to 10 Vdc in either a positive or negative direction using a single multi-turn dial.
This circuit enables the meter to be used as a null indicator for reading accuracies of 0.1%.
