The DMD-460 Series bridge amplifiers are self contained, ac or dc powered signal conditioning modules for strain gages, load cells and bridge-type sensors. The DMD 465 contains a precision differential instrumentation amplifier with voltage output. The DMD 465WB is similar, but has a frequency response to 2 kHz. The DMD 466 is similar to the above units, but with a 4 to 20 mA output instead of a voltage output.
