The Transducer Amplifier Module (TAM) is a DC amplifier with bridge. It is used to amplify physiological signals like blood pressure, 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. blood pressure.
  • TAM-D (digital display): The TAM-D has a digital numeric display and is best suited for applications with slowly changing signals, e.g. isometric or isotonic contractions, intracranial pressure or venous blood pressure.
