Servoflo introduced its MS5701 low pressure sensor with an I2C or SPI digital interface. Available in either differential or gauge models, the MS5701 can measure as low as 2.5” H2O up to 10” H2O in a differential version. The gauge model comes in ranges from +2” H2O to +20” H2O. Using the latest in MEMS technology, the MS5701 has a low supply voltage of 1.8 to 3.6V with a 1 ?A power consumption. Furthermore, the MS5701 pressure sensor has a high resolution of 0.0004” of water (0.001 mbar) and a fast conversion of 0.54 milliseconds. A 24-bit pressure and temperature output allow for integration in any microcontroller. The I2C or SPI interface communicates up to 20 MHz. With an operating temperature range of -20C to +85C, the MS5701 offers desirable accuracies. Low hysteresis and high stability of the pressure and temperature signal make the MS5701 appropriate in demanding, high performing applications. Typical uses include HVAC, respirators, ventilators, CPAP & sleep apnea, leak detection and liquid level metering.
