Model 82 UltraStable
316L SS Pressure Sensor High Performance, 19 mm 0-100 mV Output Absolute and Gage Low Pressure
Hydraulic Controls Process Control Oceanography Refrigeration/Compressors Pressure Transmitters Level Systems
DESCRIPTION
The Model 82 is a 19 mm small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing. The Model 82 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 82 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. 2. 3. 4. 5. Measured at vacuum for absolute (A), ambient for gage (G). Best fit straight line. Over the temperature range -20C to +85C with respect to +25C. 15 psi range sensors have an offset temperature error of 0.75% (Max) from -20C to +85C.
6. 7. 8. 9.
Guarantees output/input ratiometricity. Load resistance to reduce measurement errors due to output loading. Between case and sensing element. Maximum temperature range for product with standard cable and connector is -20C to +105C.
10. For gage units used at pressures below atmosphere, the span accuracy is not guaranteed.
