The MSP-100-MicroButton™ from Measurement Specialties
provides stainless steel media compatibility for the price of
competing plastic sensors. This sensor has no silicone gel or
polymeric media isolation methods to fail in contact with
water or other harsh chemicals. The all-metal diaphragm
design is immune to pressure fluctuations and subsequent
damage. The all-metal pressure enclosure has a small round
plastic housing and is available with a cable and connector.
Pressure connections are provided via an o-ring seal. Both
compensated/calibrated and uncompensated versions are
available. High volume port options
are customer specific. The
small size vs performance
and media compatibility
is provided through
solid-state
MicroFused™
technology.
