## SPECIFICATIONS 

- **PC Board Mountable Pressure Sensor** 

- **0-60 mV Output** 

- **Gage and Absolute** 

- **Low Cost** 

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 plastic 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. Ports are also available with a narrow hole or a large hole to interface with the pressure media.

## **Notes** 

1. Ratiometric to supply voltage. 

2. Best fit straight line. 

3. Over the temperature range 0-50°C with respect to 25°C. 

4. For a zero-to-full scale pressure step change. 

5. Long term stability over a one year period with constant voltage and temperature. 

6. For sensors above 100 psi, the entire sensor is required to be inside the pressure chamber. 

7. For mounting instructions, please refer to the application note “Mounting Instructions for SMT Pressure Sensors.”
