| Model 23 Low Pressure PC Board Mountable Pressure Sensor 0-1 PSI 0-100 mV Output Low Cost Temperature Compensated Medical Instrumentation HVAC Factory Automation Process Control Avionics Air Flow Management DESCRIPTION The Model 23 is a temperature compensated, piezoresistive silicon pressure sensor packaged in TO-8 configurations. It provides excellent performance and long-term stability. Integral temperature compensation is provided over a range of 0-50C using a laser-trimmed ceramic compensation board. An additional laser-trimmed resistor is included which can be used to adjust the gain of an external differential amplifier and provide sensitivity interchangeability of 1%. The sensing element used in low pressure Model 23 has a double bossed design that produces a high sensor output of 100 mV (typical) at 1 PSI. The Model 13 is also available in ranges up to 0-250 PSI. For sensors in a dual-in-line package please refer to the Models 1210 and 1220. For additional information regarding FEATURES Solid State Reliability 100mv Output Span Interchangeable Temperature Compensated Low Power uncompensated sensors, please contact the factory. DIMENSIONS STANDARD RANGES Range 0 to 1 psi 1-24 TO-8 - Low Pressure PC Board Mountable Pressure Sensor PERFORMANCE SPECIFICATIONS Supply Current: 1.5mA Ambient Temperature: 25C (Unless otherwise specified) PRESSURE RANGE 0 - 1 psi PARAMETERS Full Scale Output Span Zero Pressure Output Pressure Non-linearity Pressure Hysteresis Input & Output Resistance Temperature Error - Span Temperature Error - Zero Thermal Hysteresis - Zero Supply Current Response Time (10% to 90%) Output Noise Output Load Resistance Insulation Resistance (50 VDC) Long Term Stability Pressure Overload Operating Temperature Storage Temperature Media Weight Notes 1. Output span of unamplified sensor. 2. For most models, compensation resistors are in an integral part of the sensor package; no additional external resistors are required. Test pins must be kept open. Best Fit Straight Line.
