Lexington, MA, 02421

Press release date: July 27, 2010

Servoflo Corporation of Lexington, Massachusetts is pleased to announce the 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 mA 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 allows for integration to any microcontroller. The I2C or SPI interface communicates up to 20 MHz.

With an operating temperature range of -20C to +85C, the MS5701 offers excellent accuracies. For example, a model calibrated for 5" of water (differential) has an accuracy of 0.04" at 25C and 0.1" over the entire operating temperature range. Low hysteresis and high stability of the pressure and temperature signal make the MS5701 reliable in demanding, high performing applications. Typical uses for the MS5701 include HVAC, respirators, ventilators, CPAP & sleep apnea, leak detection, liquid level metering and more.

The MS5701 low pressure sensor is priced at $18 each in quantities of 1,000. For complete specifications, please visit
