Model 47 UltraStable Medical Instrumentation PC Board Mountable Pressure Sensor Calibration 0-100 mV Output Process Control Gage and Absolute Pressure Factory Automation Wide Temperature Range Air Flow Management Leak Detection DESCRIPTION The Model 47 is a high performance, temperature compensated, piezoresistive silicon pressure sensor packaged in a differential TO-8 configuration. It provides excellent performance and long-term stability. Differential pressure ranges from 0-15 PSI to 0-250 PSI are available. Integral temperature compensation is provided over a range of -20C to +85C 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 35) please contact the factory for FEATURES additional information.
