MS5541-30C Digital Pressure & Altimeter
Brand: American Sensor Technologies IncThe 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 4 kV 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.
