MS1451 PC Board Mountable Pressure Sensor Description
The MS1451 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. Caps are also available with a narrow hole or a large hole to interface with the pressure media.
