The Model 437 self-contained, DC powered signal conditioner works with load cells and transducers utilizing full bridge strain gages. It contains a precision instrumentation amplifier with an isolated, filtered output and a regulated, low-noise, adjustable output bridge excitation source. Notable features include a bridge balance pot and high gain capability to accurately condition load cell weighing systems with large tare offsets and small live load signals. Other features include an isolated 4 to 20 mA or 0 to 20 mA output capable of driving a 1-kΩ loop, an 80% tare offset capability, and an excitation supply capable of driving four 350Ω load cells.
