Description
Amplified Pressure Sensor
Manufacturer
Servoflo Corporation
Datasheet
40SP5004.01
DESCRIPTION
The Silicon Microstructures SM5852 series
of OEM pressure sensors combines state-
of-the-art pressure sensor technology with
CMOS digital signal processing technology
to produce an amplified, fully conditioned,
multi-order pressure and temperature
compensated sensor in a dual in-line
package (DIP) configuration.
Combining the pressure sensor with a
custom signal conditioning ASIC in a single
package simplifies the use of advanced
silicon micromachined pressure sensors.
Now, the pressure sensor can be mounted
directly to a standard printed circuit board
and an amplified, high level, calibrated
pressure signal can be acquired from the
digital interface or analog output. This
eliminates the need of additional circuitry,
such as a compensation network or micro-
controller containing a custom correction
algorithm.
The SM5852 Series pressure sensors are
based on SMI's highly stable, piezoresistive
pressure sensor chips mounted on a
ceramic substrate. An electronically
programmable ASIC is contained in the
same package to provide calibration and
temperature compensation.
The model SM5852 is designed for
operating pressure ranges from 0.15 PSI up
to 1.5 PSI. For both models, the sensor
output is ratiometric with the supply voltage.
