DESCRIPTION
The SM5650 Series of OEM pressure
sensors are fully calibrated, temperature
compensated low-pressure sensors in dual
in-line packages for printed circuit board
mounting. These sensors offer improved
performance as well as the option for either
constant current or constant voltage
excitation.
The SM5600 Series pressure sensors are
constructed by attaching a highly stable
piezoresistive pressure sensor chip to a
ceramic substrate. Thick film resistors on
the ceramic are laser trimmed during
manufacturing to provide zero offset
calibration, temperature compensation for
zero offset, and temperature compensation
for sensitivity. In the Model SM5651, an
additional resistor is trimmed to normalize
the output of an external differential amplifier
to provide span calibration when the sensor
is driven by a constant current supply. In
the Model SM5652, a constant voltage
supply can be used and the normalized
output span of each sensor can then be
easily amplified.
The model SM5651 is designed for constant
current excitation.
The model SM5652 is designed for constant
voltage excitation.
Various pressure port configurations are
available for flexibility in matching this
product to specific applications.
