SM5611/SM5612 OEM Pressure, Constant Current DIP OEM Pressure, Constant Voltage DIP OEM PRESSURE TRANSDUCER FULLY TEMPERATURE COMPENSATED AND CALIBRATED DUAL-IN-LINE PACKAGE DESCRIPTION The SM5600 Series of OEM pressure sensors are fully calibrated, temperature compensated pressure sensors in dual in- line packages for printed circuit board mounting. These sensors offer improved performance as well as the option for either constant current or constant voltage excitation. Ultra-low pressure ranges are also available (see SM5651/SM5652 datasheet), resulting in the broadest selection of standard pressure ranges in the FEATURES industry. 15, 30, 60, and 100 PSI FS Ranges The SM5600 Series pressure sensors are Available constructed by attaching a highly stable Constant voltage and constant current piezoresistive pressure sensor chip to a versions ceramic substrate. Thick film resistors on Easy to use dual in-line package (DIP) the ceramic are laser trimmed during Wide 0-60C compensated temperature manufacturing to provide zero offset range calibration, temperature compensation for Span calibration to 2% zero offset, and temperature compensation Zero offset calibration for sensitivity. In the Model SM5611, an High performance, stable packaged additional resistor is trimmed to normalize silicon chip the output of an external differential amplifier Gage, differential, and absolute to provide span calibration when the sensor pressure configurations is driven by a constant current supply. In the Model SM5612, a constant voltage supply can be used and the normalized output span of each sensor can then be APPLICATIONS easily amplified. Barometric Pressure The model SM5611 is designed for constant Medical Instrumentation current excitation. Environmental Control The model SM5612 is designed for constant Altimeters voltage excitation. Automotive Diagnostics Appliances Various electrical pin and pressure port configurations are available for flexibility in matching this product to specific applications.
