PLUGSYS Transducer Amplifier Modules (TAM-A and TAM-D)
Universal DC bridge amplifiers used to amplify physiological signals such as blood pressure, contraction force or contraction displacement.
Use with PLUGSYS Case Types 601, 603 or 609.
Please see Description for a list of recommended transducers.
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. Use with PLUGSYS Case Types 601, 603 or 609.
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. It can be paired with our PLUGSYS Servo Controller for Perfusion (SCP) and a constant pressure enabled syringe or analog speed controllable peristaltic pump to complete a constant pressure perfusion setup.
- TAM-A Modified: With modified low pass filter 10, 30 and 50 Hz, LED bargraph display
