Model 13 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 13 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 0-50°C 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 13 has a double bossed design that produces a high sensor output of 100 mV (typical) at 1 PSI. This package style 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 uncompensated sensors, please contact the factory.
