MODEL 86 Ultrastable 316L SS Pressure Sensor * Hydraulic Controls High Performance, Small Profile * Process Control 0-100 mV Output Absolute and Gage Low Pressure * Oceanography * Refrigeration/Compressors * Pressure Transmitters * Level Systems DESCRIPTION Pressure 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 silicon 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 sensors and high pressure stainless steel sensors are also available. Please contact the factory for more information.

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 -20C to +85C with respect to +25C. 5. 15 psi range sensors have an offset temperature error of 0.75% (Max) from -20C to +85C. 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 -20C to +105C. 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. ORDERING INFORMATION APPLICATION SCHEMATIC CONNECTIONS Rad.
