MS5803-01BA Miniature Variometer Module High Resolution Pressure Module

MS5803-01BA Miniature Variometer Module High Resolution Pressure Module Model Number :MS5803-01BA  
GENERAL DESCRIPTION
The MS5541-30C is the high-pressure version of MS5541C pressure sensor module. The MS5541-30HM is the high endurance pad technology version of MS5541-30C pressure sensor module. It contains a precision piezoresistive pressure sensor and an improved version of the 16 Bit Micropower Sensor interface IC known from the MS5535C. The ESD sensitivity has been improved to 4kV on all pins. In addition to this the MS5541-30C is from its outer dimensions compatible to the MS54xx series of pressure sensors. It uses an antimagnetic polished stainless steel ring for sealing with O-ring. The sensor provides 16 Bit pressure and temperature data via a 3 wire serial interface that can be easily interfaced with 4 Bit low power microcontrollers. 64 Bit of factory programmed PROM provides calibration data for a highly accurate pressure and temperature calculation.
