SYRI NG E PUMP A CC E S S O R IE S Pressure Transducers for PHD ULTRA™ CP Syringe Pump Transducer Amplifier Module (TAM-A and TAM-D) APT300 Blood Pressure Transducer SYRINGE PUMP ACCESSORIES Pressure Transducers for PHD ULTRA™ CP Syringe Pump 42 The Transducer Amplifier Module is a DC amplifier with bridge. It is used to amplify signals from transducers that are based on a resistive Wheatstone bridge. Transducers with a built-in preamplifier can also be connected. The TAM series amplifies the signal to a 0-10 V range making it ideal for use with the CP Pump series, which operates best with a full 0-10 V input range. As they are modular, a power supply case needs to be chosen. Cases are available that hold up to 2, 5, or 10 TAM modules. Choose from two: TAM-A (analog) and TAM-D (digital). 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/phasic waveforms (e.g. blood pressure). The TAM-D has a digital numeric display and is best suited for applications with slowly changing signals, e.g. perfusion pressure, isometric or isotonic contractions, or intracranial pressures. For applications involving the CP Pump, the TAM-D is the appropriate choice. We have a range of transducers that interface directly with the TAM amplifiers. The APT300 transducer is an inexpensive pressure transducer which can be used to measure arterial blood pressures in all species, even on mice with a high heart rate. It can be used for measurement of arterial pressure in vivo as well as for perfusion pressures in isolated perfused organs such as heart or kidney. It can also be used to measure isovolumetric left ventricular (using a balloon) pressures in isolated hearts from mice up to rabbits or pigs. The transducer consists of a contact plate with cable and the exchangeable transducer head, which can easily be replaced. Contact plates with cables for different amplifier types are available.
