High Endurance (HE version)
The MS5803-30BA is a new generation of high resolution
pressure sensors with SPI and I2C bus interface. The MS5803-
30A HE is the high endurance pad technology version of the
MS5803-30BA pressure sensor module. It is optimized for depth
measurement systems with a water depth resolution of 2.5cm and
below. The sensor module includes a high linear pressure sensor
and an ultra low power 24 bit ΔΣ ADC with internal factory
calibrated coefficients. It provides a precise digital 24 Bit pressure
and temperature value and different operation modes that allow
the user to optimize for conversion speed and current
consumption. A high resolution temperature output allows the
implementation of a depth measurement systems and
thermometer function without any additional sensor. The MS5803-
30BA can be interfaced to any microcontroller. The
communication protocol is simple, without the need to
programming internal registers in the device. The gel protection
and antimagnetic stainless steel cap make the module water
resistant. This new sensor module generation is based on leading
MEMS technology and latest benefits from MEAS Switzerland's
proven experience and know-how in high volume manufacturing
of pressure modules have been widely used for over a decade.
This sensing principle employed leads to very low hysteresis and
high stability of both pressure and temperature signal.
