Product Description:
NPA-700B-005D Sleep Respiratory System 35kpa Pressure Sensor
Features:
NPA series pressure sensors are compact in size and offer an
economical and ideal solution for many current applications that
require immediate installation and use without complex calibration.
The NPA series products adopt SOIC14 surface mount packaging. The
measured pressure comes in three forms: gauge pressure, absolute
pressure or differential pressure. The output signals are available
in three types: mV (uncalibrated), amplified analog signal and
serial digital output. This series of sensors is particularly
suitable for surface mount installation on printed circuit boards.
To simplify production, installation and use, products can be
delivered in the form of roll and tape packaging.
