General description Features Pressure transducer PHPS-8500 is a pressure and temperature sensing device specially developed for ultra-low pressure ranges and demanding space constrictions. High performance and accuracy enables use of this transducer in many applications including differential pressure measurements. Standard 2nd order temperature and pressure compensation provides 0,5% FS total error over 0°C to 70°C temperature range. Single power supply (3,3V - 5.5V), customized compensated pressure and temperature ranges, standard digital I2C, SPI or one wire interfaces or analog voltage output provides OEM users maximum freedom for any type of application with dry air or non-corrosive gases or liquids. Family PHPS-8500 provides easy integration using small SMD package with footprint pads on short edges leaving enough room for easier routing for the end application. SMD housing is reflow mountable with fast stabilisation after soldering process. Pressure ports with their flexibility in different options can accept standard pneumatic tubes or can be customised for integration into end customer housings with straight pressure ports. Different pressure ranges are available for this group starting from 1mBar up to 7bar. Applications • Sleep Apnea, CPAP • Ventilators / Respirators • HVAC • Medical instrumentation • Air/gas flow monitoring • Sport equipment • Process control • Pneumatics control • Leak detection • Consumer devices Pressure ranges from 0-1mbar to 0-7bar Single 3,3V or 5V supply voltage Standard 0,5V - 4,5V voltage output Digital I2C or SPI output (pressure + temperature) Standard temperature compensated range (0-70°C), other possible Operating temperature range -25...+85 °C Total pressure accuracy down to max 0,5%FS (with all effects included). Total temperature accuracy max 1°C (within compensated temp. range). Adjustable output resolution (up to 15 bits) versus sampling rate (up to 3.9kHz) Alarm or PWM output Outstanding offset stability.

PHPS-8500 Miniature Pressure Transducer Specification notes 1) Over pressure is the maximum pressure which may be applied without causing damage to the sensing element. 2) Burst pressure is the maximum pressure which may be applied without causing leakage damage to the sensing element. Analog output signal is ratiometric to power supply Vcc, digital signal is not ratiometric to the power supply. Offset voltage is the voltage output at zero pressure. Full scale output is the voltage output at full pressure range. Full scale span is the algebraic difference between the output at full scale pressure...
