Uncompensated, Absolute Pressure
Sensor
Uncompensated, Absolute
Pressure Sensor
The MPS series of surface mount pressure sensors
provides a cost effective method of measuring
absolute and or gauge pressure in a fully packaged
format. The packaging formats of COB and surface
mount cavity packages, provides the product with an
application specific footprint that is particularly useful
in various sensor applications. The Memstech piezoresistive silicon pressure sensors can be used in most
general applications within a variety of industry uses:
Data recording, on board and Remote Diagnostics
A soft gel coating provides some measure of
environmental protection, none the less, it is not
recommended to expose this sensor to conditions of
high moisture or corrosive chemicals. The sensor is
housed in a surface mount package, and uses
materials that are compliant with United States of
America and European Union standards on
hazardous material content.
FEATURES
The MPS series sensors are uncompensated, and
can be used with clean dry gases such as air,
nitrogen and other like gases. The product offers a 5
pin open bridge configuration for electrical connection
to facilitate analogue calibration of offset and span, if
required. A 4 pin closed bridge configuration is also
available. 4 choices of footprint facilitate compatibility
with existing component layouts. Applications use
with voltage sourcing is recommended to give the
maximum sensor performance in accuracy with the
conservation of battery power in portable applications.
A ratiometric signal processing and acquisition
system should be used if possible.

SPECIFICATION NOTES
1. Operating and storage temperature to strictly not exceed stated values
2. Pressure unit conversion --- 1 atm=101.325 kPa=1013.25 hPa=14.6956 psi
3. Supply voltage DC and AC up to 5KHz.
4. Operating pressure and temperature. The nominal pressure under which the device can be exposed under
normal operating conditions. Unless explicitly stated, other specifications are rated over the operating pressure
and temperature ranges.
5. Proof pressure and temperature. The extremes of temperature and pressure that the device can withstand
without performance degradation.
6. Supply Voltage is the nominal operating voltage. The device output is ratio metric (scales with the supply)
within the stated range.
7. Stated Warm up time is a recommended time after power up before measurement stability is reached with the
rated accuracy range.
8. Total error at half span is based on the difference between the half span measurement and a straight line
projection over the span of the device where NL% =
O ( S2 ) − O ( 0 )+2O ( S )
O ( S2 )
x100
9. Accuracy represents the expected deviation of the sensor value from the ideal linear behavior over
temperature and pressure, on fixed mounting configurations after pressure and electrical response times and
warm up periods are taken into account, and include thermal and pressure linearity and hysteresis effects over
the life of the sensor.

9. Accuracy represents the expected deviation of the sensor value from the ideal linear behavior over
temperature and pressure, on fixed mounting configurations after pressure and electrical response times and
warm up periods are taken into account, and include thermal and pressure linearity and hysteresis effects over
the life of the sensor.
10 Offset stability represents the proportion of the deviation in offset (zero pressure output) at fixed temperature
T=25+-5C, over the life of the sensor, and includes the effects of thermal and pressure hysteresis as well as
other sources of drift.
11. Top side pressure application.
12. Resistance is measured by sourcing a constant current of 0.7mA, which represent the typical operating
conditions.
13. TCO, TCR & TCS are tested from 0 Deg C to 50 Deg C, based on a linear approximation.
14. Terminology
a) OFFSET VOLTAGE (@ 25 °C) Output voltage under no-load / no-pressure (vacuum) conditions.
b) OUTPUT SPAN VOLTAGE (@ 25 °C) Difference between rated output voltage at the maximum operating
pressure applied and offset voltage. The range of output change expected over the full range of pressure
changes that can be applied to the device.
c) ZIN (@ 25 °C) Input impedance at no load and ambient pressure conditions
d) ZOUT (@ 25 °C) Output impedance at no load and ambient pressure conditions
e) LINEARITY (@ 25 °C) Linearity is expressed in terms of the deviation from the straight line connecting the nopressure (vacuum) condition and rated voltage when the pressure is varied from the no-pressure condition to
the span pressure. It is expressed as deviation (D1) found when the rated voltage is halved as a ratio to full
scale (FS)
f) PRESSURE HYSTERESIS (@25°C) Pressure hysteresis is expressed as difference (D2) between the
response to an increasing pressure in no-load condition and a reducing pressure as a ratio to full scale (FS)
when the pressure is reduced in the no-load condition after the pressure has been increased form the no-load
condition to the rated pressure. In other wards the difference in output voltage before the sensor is subjected to
rated pressure and immediately after reducing from the rated pressure as a ratio to full scale (FS).
g) OFFSET VOLTAGE – TEMPERATURE CHARACTERISTICS. This is the variation in the offset voltage in
response to the change in the ambient temperature. It is expressed as the absolute difference (? 1 or ? 2)
between the offset voltage at 0°C or at 50 °C and offset voltage at 25 °C, which ever is higher, as a ratio to full
scale (FS) |? 1|/FS x 100 or |? 2|/FS x 100, which ever is higher.
h) SENSITIVITY – TEMPERATURE CHARACTERISTICS
i) This is the variation (full scale <FS> variation) in the sensitivity in response to the change in the ambient
temperature. It is expressed as the absolute difference (between FS1 and FS or FS2 and FS) between full
scale (FS1,FS2) at 50 °C and full scale at 0°C (FS) , whichever is higher, as a ratio to full scale(FS) at 25°C
|FS1-FS/FS x 100 or |FS2-FS|/FS x 100, which ever is higher. Measurements on product for binning purposes
are performed at ambient and warm conditions.
