Pressure sensor delivers long-term stability for liquid measurement applications

Mouser now stocks the TE Connectivity/Measurement Specialties MS5849 board mount pressure sensor. Designed to supply precise digital 24-bit pressure and temperature values, the pressure sensor provides multiple operation modes that enable the user to optimise for conversion speed and current consumption. The pressure sensor delivers excellent long-term stability for various applications, including safety devices in seawater, portable medical devices, disposable drug treatment, and liquid measurement.

The device is an ultra-compact, chlorine-resistant, high-resolution pressure sensor with an SPI/I2C bus interface. The new generation of sensors, based on leading MEMS technology, was designed using TE Connectivity's experience in high-volume manufacturing of pressure sensors, which have been widely used for over three decades. The pressure sensor's compact dimensions (3.3mm x 3.3mm x 2.7mm) and low power consumption enable easy integration into user applications.

The device can be interfaced with virtually any MCU. The high-linearity pressure sensor integrates an ultra-low power 24-bit ΔΣ ADC with internal factory-calibrated coefficients. The pressure sensor features a 1.5V to 3.6V operating supply voltage range, fast conversion down to 0.37ms, low power down to 0.34µA, and a 100nf VDD capacitor. The pressure sensor also provides an operating pressure range of 300mbar to 30,000mbar and an operating temperature range of -40C to 110C, and it delivers fast conversion down to 0.37ms, FIFO mode, a programmable filter, and a 64-bit serial number.
