DESCRIPTION
The Model 86 is a small profile, media compatible,
piezoresistive silicon pressure sensor packaged in a 316L
stainless steel housing. The Model 86 is designed for O-ring
mounting. The sensing package utilizes silicone oil to transfer
pressure from the 316L stainless steel diaphragm to the sensing
element.
The Model 86 is designed for high performance, low
pressure applications. A ceramic substrate is attached to the
package that contains laser-trimmed resistors for temperature
compensation and offset correction. An additional lasertrimmed resistor is included which can be used to adjust an
external differential amplifier and provide span
interchangeability to within ±1%.
Sensors with threaded pressure fittings, weldable flush

Notes
1. For amplified output circuits see application note TN-003.
6.
Guarantees output/input ratiometricity.
2.
Measured at vacuum for absolute (A), ambient for gage (G).
7.
Load resistance to reduce measurement errors due to output loading.
3.
Best fit straight line.
8.
Between case and sensing element.
4.
Over the temperature range –20°C to +85°C with respect to +25°C.
9.
5.
15 psi range sensors have an offset temperature error of ±0.75%
(Max) from –20°C to +85°C.
Maximum temperature range for product with standard cable and
connector is –20°C to +105°C.
ORDERING INFORMATION
10. For gage units used at pressures below atmosphere, the span accuracy
is not guaranteed.
