DESCRIPTION
The Model 1451 is a piezoresistive silicon pressure sensor
packaged in a surface mount configuration. It is intended for
high volume applications where small size, light weight, low
cost, and compatibility with automated assembly equipment are
required.
The pressure sensor is available with a gage or absolute
pressure sensing chip that is attached to a surface mountable
ceramic substrate. A cap is attached to the ceramic substrate,
protecting the chip and providing the pressure port.
The devices are shipped in plastic anti-static shipping tubes
for use with automated production equipment. The drawing
shows a standard tube version. Caps are also available with a
Narrow hole or a large hole to interface with the pressure
media.
