DESCRIPTION
This ia a micromachined piezoresistive silicon pressure sensor. It
is designed for OEM applications where compatibility with
corrosive media must be maintained. The sensor chip is
mounted on a TO style header, which is resistance welded to a
316 stainless steel package. A 316 stainless steel convoluted
isolation diaphragm is welded to the package, sealing a small
volume of silicone oil between the diaphragm and the sensor
chip. The ISO pressure housing utilizes the oil column to couple
the piezoresistive sensor to the isolation diaphragm. A thickfilm
ceramic compensation board with laser trimmed resistors, and
an additional gain set resistor to normalize pressure sensitivity
are an integral part of the sensor package. A variety of threaded
process fittings are available. Fittings include standards like 1/4
and 1/8 NPT, 1/4 BSP as well as custom process fittings.
Electrical options include cable and connector.

1% interchangeability with gain
7. Load resistance to reduce measurement errors due to output loading.
8. Between case and sensing element.
set resistor. See Application Note TN-003.
2. Measured at vacuum for absolute (A), ambient for gage (G).
3. Best fit straight line.
9. Maximum temperature range for product with standard cable and
connector is –20°C to +105°C.
4. Over Temperature range: -20°C to +85°C Span with respect to +25°C.
10. Weight depends upon configuration (cable, connector, pressure fitting).
5. 15 psi range sensors have a temperature error of 0.75% (Max) of
Zero from -20°C to 85°C.
11. For gage units used at pressures below atmosphere, the span accuracy
is not guaranteed.
6. Guarantees output/input ratiometricity.
