DESCRIPTION
The
MSP340 pressure transducer from the Microfused™ line of MEAS is
great for high volume,
commercial and
industrial applications. This series is suitable for measurement of
liquid or gas pressure, even
for
difficult media such as contaminated water, steam, and mildly
corrosive fluids.
The
transducer pressure cavity is machined from a solid piece of 17-4
PH stainless steel. The standard
version
includes a 1/4 NPT pipe thread allowing a leak-proof, all metal
sealed system. There are no O-rings,
welds or
organics exposed to the pressure media. The durability is
excellent.
MEAS’
proprietary Microfused™ technology, derived from demanding
aerospace applications, employs
micromachined
silicon piezoresistive strain gages fused with high temperature
glass to a stainless steel
diaphragm. This
approach achieves media compatibility simply and elegantly while
providing an exceptionally
stable sensor
without the p-n junctions of conventional micromachined
sensors.
This product is
geared to the OEM customer who uses medium to high volumes. The
standard version
is
suitable for many applications, but the dedicated design team at
our Transducer Engineering Center stands
ready to provide a semi-custom design where the volume and application warrants.
