| Models 32, 33 Medium Pressure PC Board Mountable Pressure Sensor 0-100 mV Output Differential Pressure Temperature Compensated Medical Instrumentation HVAC Process Control Vacuum Measurement Air Flow Management DESCRIPTION The Models 32 and 33 are temperature compensated, piezoresistive silicon pressure sensors packaged in TO-8 configurations. They provide excellent performance and longterm stability. Differential pressure ranges from 0-2 PSI to 0-250 PSI are available. Integral temperature compensation is provided over a range of 0-50C using laser-trimmed resistors. An additional laser-trimmed resistor is included in the Model 33 to normalize pressure sensitivity variations by programming the gain of an external differential amplifier. This provides sensitivity interchangeability of 1%. Please refer to the low pressure section for information on products with operating pressures less than 0-2 PSI. An uncompensated sensor (Model 30) is also available. For sensors FEATURES TO-8 Package 0.1% Non-linearity 0.5% Temperature Performance 1.0% Interchangeable Span (provided by gain set resistor) Solid State Reliability Low Power in a dual-in-line package please refer to the Models 1210 and 1220. Please contact the factory for additional information.
