Description
T
he MSP series pressure transducers set a new price-performance standard
for low cost, 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 or
gases.
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.
Measurement Specialties 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 providing an exceptionally stable sensor without the p-n junctions
of conventional micromachined sensors.
This product is geared to the OEM customer using 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.
