PLUGSYS DC Bridge Amplifier Module (DBA)
Universal DC bridge amplifiers used to amplify physiological signals such as blood pressures, respiratory airflow, airway pressure, contraction force or contraction displacement. Use with PLUGSYS Case Types 601, 603 or 609. Advances low pass filter possibilites
The DC Bridge Amplifier Module (DBA) is a universal DC bridge amplifier for connection of transducers to measure blood pressure, pulmonary air flow, airway pressures, conraction force, displacement, etc. It is used to amplify dynamic physiological signals like blood pressures, contraction force or contraction displacement using transducers based on a resistive Wheatstone bridge.
The DBA is equipped with an analog LED bar graph signal indicator and is best suited for applications which require the monitoring of dynamic signals, e.g. pulsatile blood pressures, respiratory air flow, respiratory pressures, force, etc.
This module has advanced low pass filter capabilities compared to the TAM-A module.
