Description
The Model DCM 437 is a self-contained, DC powered signal conditioner for bridge type instrumentation. It contains
a precision differential amplifier with filtered output and a highly regulated, low noise, adjustable output bridge
excitation source. What sets the DCM 437 apart is a Bridge Balance pot and high gain capability to accurately
condition load cell weighing systems with large tare offsets and small live load signals. The unit is completely
encapsulated for use in rugged environments.
