Model 13 Medium Pressure Medical Instrumentation PC Board Mountable Pressure Sensor HVAC 0-100 mV Output Barometric Pressure Gage and Absolute Pressure Process Control Temperature Compensated Vacuum Measurement Air Flow Management DESCRIPTION The Model 13 is a temperature compensated, piezoresistive silicon pressure sensor packaged in TO-8 configurations. It provides excellent performance and long-term stability. Gage and absolute pressure ranges from 0-2 PSI to 0-250 PSI are available. Integral temperature compensation is provided over a range of 0-50°C using laser-trimmed resistors. An additional laser-trimmed resistor is included 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. For an uncompensated sensor (Model 10) please contact the factory for additional information.
