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 FEATURES sensors and high pressure stainless steel sensors are also O-Ring Flush Mount –20°C to +85°C Compensated Temperature Range ±0.1% Pressure Non-linearity ±1.0% Interchangeable Span (provided by gain set resistor) Solid State Reliability Low Power available.

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.
