Description
All-purpose or Universal input for
physiological signals. Handles a wide
variety of signals such as biopotential
signals, pulmonary pressure and flow
signals, blood pressure and flow signals,
temperature signals, and various
other inputs.
Features 16 channels of Digital-to-Analog
output for use with other equipment.
Provides Filtering, Output Resolution
and user selectable Output Ranges
as well as automatic calculation of
Units/Volts of the Output signal.
Designed specifically for use with
the Validyne DP-45 and DP-250
Pressure Transducers for accurate
pulmonary pressure, volume and
flow measurements.
Optimized filtering and Input Range
for specific applications such as
pulmonary pressures, blood pressures
and isolated organ.
Ability to acquire Bi-polar measurements
from up to 32 high level laboratory
inputs simultaneously.
Standard laboratory BNC connections
easily allow high level signals to be
brought into Ponemah for association
with other signals.
Delivers continuously variable input.
The Transducer signal conditioner can
be used for a variety of DC, pressure
or tension measurements.
