DESCRIPTION
The Model 1471 is a piezoresistive silicon pressure sensor,
calibrated at room temperature. 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 avail-
able with a narrow hole or a large hole to interface with the
pressure media.

Notes
1. Trimmed at room temperature. Does not include
temperature dependence of offset and span
2. For absolute pressure sensor. Offset limit will be
±5mv/V
3. Best Fit Straight Line
4. Over the temperature range 0-50ºC with respect to 25º C
5. For a zero-to-full scale pressure step change
6. 10Hz to 1kHz
7. For sensor above 100 psi applications, the entire sensor is required
to be inside the pressure chamber
8. Gel fill coating is only offered with the wide hole port option.
9. Tighter accuracy or other outputs can be achieved. Please contact
factory
