Model 86 UltraStable 316L SS Pressure Sensor High Performance, Small Profile 0-100 mV Output Absolute and Gage Low Pressure Hydraulic Controls Process Control Oceanography Refrigeration/Compressors Pressure Transmitters Level Systems 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 FEATURES sensors and high pressure stainless steel sensors are also O-Ring Flush Mount -20C to +85C Compensated Temperature Range 0.1% Pressure Non-linearity 1.0% Interchangeable Span (provided by gain set resistor) Solid State Reliability Low Power available. Please contact the factory for more information.
