The Transducer Amplifier Module (TAM) is a DC bridge amplifier. It is used to amplify signals like pulsatile blood pressures, respiratory airflow, airway pressures, contraction force and contraction displacement using transducers based on a resistive Wheatstone bridge. Transducers with a built-in preamplifier which have a high level DC output voltage can also be connected.

Choose from:

  • TAM-A (analog): The TAM-A 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 airflow, airway pressures, contraction force or contraction displacement on tissue studies.
  • TAM-D (digital display): The TAM-D has a digital numeric display and is best suited for applications with slowly changing low pulsatile signals, e.g. constant blood pressures, slow isometric or isotonic contractions, intracranial pressure or venous blood pressures.
  • TAM-A Modified: With modified low pass filter 10, 30 and 50 Hz, LED bargraph display
