Designed for conditioning strain-gauge and bridge signals, this amplifier provides a selectable gain of 40 to 250 and offers a wide-band response to 2 kHz for fast dynamic measurements. It accepts bridge, load cell, and transducer signals and operates from an AC or DC supply. Great for load, force, and weighing measurement systems.

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 similar DMD-465WB has a frequency response to 2 kHz, while the DMD-466 has a 4 to 20 mA output instead of a voltage output.
