MS5541-30C (RoHS*) MINIATURE 30 bar MODULE
DESCRIPTION
0 – 30 bar absolute pressure range
6 coefficients for a software compensation stored
on-chip
Piezoresistive silicon micromachined sensor
Integrated pressure sensor 6.2x6.4 mm
16 Bit ADC
3-wire serial interface
1 system clock line (32.768 kHz)
Low voltage and low power consumption
RoHS-compatible & Pb-free*
The MS5541-30C is the high-pressure version of MS5541C 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.
