last update January 29, 2014 DATASHEET reference Pressure sensor family SPD-dil family page 1/5 Smartec Pressure Sensor (bridge output) Features * Commercial grade * DIP version for high volume production * Gauge or absolute pressure * Resistive bridge technology * Voltage or current excitation Applications * Medical applications * Blood pressure * Portable Gauges * Process control * HVAC controls Product description The Smart Pressure Device SPD series of pressure sensors are silicon based and encapsulated in modified plastic Dual In Line packages, to accommodate six pins for through-board printed circuit mounting. The sensors come in two distinct types: Gauge and absolute. The gauge type merely measures the pressure with respect to the atmospheric pressure. The absolute type contains a reference vacuum chamber, which is formed on the die during manufacturing. The output voltages of both types are proportional to the pressure that is measured. Various pressure ranges are available. On request, other ranges and encapsulations can be supplied. Please contact our sales department for more information. Because of its bridge resistance value, the SPD pressure sensor is especially suited for use in combination with the Universal Transducer Interface (UTI03), which gives an easy and very accurate interface to a digital environment. last update January 29, 2014 reference SPD series pressure sensor SPD-dil family page 2/5 SPD bridge series Performance Characteristic (Measured 5V excitation and 25 C.)
