Model 43 Medium Pressure PC Board Mountable Pressure Sensor 0-100 mV Output Gage and Absolute Pressure Temperature Compensated Medical Instrumentation HVAC Process Control Vacuum Measurement Air Flow Management DESCRIPTION The Model 43 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. An uncompensated sensor (Model 40) is also available. For sensors in a dual-in-line package please refer to the Models 1210 and FEATURES 1220. Please contact the factory for additional information.
