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.
