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.

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.
