1/5 Features General description PHPS-7500 is a new generation of ceramic pressure sensors made with low-temperature cofired ceramic (LTCC) technology and a patented sensor-construction solution. The pressure sensor element is made with LTCC technology using piezo-resistive principle to detect the pressure. The LTCC material is compatible with many types of aggressive media like water, hydraulic oils, diesel and others, which makes the sensor suitable for pressure measurements in harsh environments. Special protection of the piezo-resistors also makes this sensor suitable for wet-wet applications. High performance and accuracy are achieved with the patented sensor construction, which allows this sensor to be used in many applications, and with its compact and convenient design it is very suitable for OEM users. The PHPS-7500 pressure sensors are amplified and temperature compensated from 0 to 70 C with special signal conditioning electronics. The PHPS-7500 family consists of standard 100 mbar, 350 mbar, 1 bar, 2bar, 4bar and 10 bar differential pressure ranges. Suitable for harsh environment and wetwet applications Single 5 supply voltage Wide compensated range (0-70 C) Total accuracy down to 0.75%FS (typ.) over 0-70 C, all effects included. Standard 0.5 4.5 voltage output and digital I2C output available (pressure & temperature) High performance OEM Applications Pressure measurements of gases and liquids Instrumentation & measuring equipment Process control Level control systems HAC Leak detection

4/5 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. 3) Analog output signal is ratiometric to power supply cc digital signal is not ratiometric to the power supply. 4) Offset voltage is the voltage output at zero pressure. 5) Full scale output is the voltage output at full pressure range. 6) Full scale span is the algebraic difference between the output at full scale pressure range and offset. 7) Accuracy of offset and span includes all effects (nonlinearity, pressure hysteresis and repeatability) at room temperature and represents maximum deviation of sensor signal from ideal characteristic. 8) Total accuracy includes all effects (offset, span, nonlinearity, pressure hysteresis and repeatability) included with all temperature effects of offset and span. It describes overall error and represents maximum deviation of sensor signal from ideal characteristic in compensated temperature range from 0 C to 70 C. 9) Repeatability is defined as typical deviation of the output signal after 10 pressure cycles. 10) Nonlinearity is defined as the BFSL (best fit straight line) across entire pressure range. 11) Media compatibility on pressure port P1,P2 : noncorrosive gases/fluids to epoxy, LTCC ceramics and LCP plastics.
