DESCRIPTION
The Model 86 is a small profile, media compatible, piezore-
sistive silicon pressure sensor packaged in a 316L stainless
steel housing. The Model 86 is designed for O-ring mounting.
The sensing package utilizes silicon oil to transfer pressure
from the 316L stainless steel diaphragm to the sensing ele-
ment.
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 laser-
trimmed 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
sensors and high pressure stainless steel sensors are also
available. Please contact the factory for more information.

PERFORMANCE SPECIFICATIONS
All parameters measured at 1.5mA drive and at 25°C after 10 second warm up, unless otherwise specified. Unless specifically indicated, only those parameters
indicated as tested are verified on each part. Parameters are specified for the compensated version only.
1. For amplified output circuits see application note TN-003.
2. Measured at vacuum for absolute (A), ambient for gage (G).
3. Best fit straight line.
4. Over the temperature range –20°C to +85°C with respect to +25°C.
5. 15 psi range sensors have an offset temperature error of ±0.75%
(Max) from –20°C to +85°C.
6. Guarantees output/input ratiometricity.
7. Load resistance to reduce measurement errors due to output loading.
8. Between case and sensing element.
9. Maximum temperature range for product with standard cable and
connector is –20°C to +105°C.
10. For gage units used at pressures below atmosphere, the span accuracy
is not guaranteed.
11. Standard gauge units are not recommended for vacuum applications.
For vacuum applications below 1/2 atmosphere, contact factory.
