General Description
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.
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.
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.
