Absolute pressure sensor MS5541
The MS5541 pressure measurement miniature module consists of a SMD-hybrid device including a piezoresistive pressure cell and an ADC-Interface IC. It provides 16 Bit data words from a pressure- and temperature-dependent voltage. This sensor is obsolete and should not be considered for new designs.
Additionally, the module contains 6 readable coefficients for a highly accurate software calibration for the pressure and temperature measurement. The MS5541 is a low-power, low-voltage device with automatic power down (ON/OFF) switching. A 3-wire interface is used to communicate with a microcontroller.
The devices have a very low standby current. The optimal compromise of refresh rate and average current consumption can individually be defined by the application software.
MS5541-CM: protected by a metal ring filled with silicon gel on a ceramic hybrid 6.2×6.4mm
Pressure range: 0 … 200 PSI abs.; operating temperature: -40 … +85°C
The MS5541-C is fully software compatible with the previous version MS5541-B.
The MS5541 is also available in a 435PSI version.
*Modules are pressure sensors, whose output signals have to be calculated by an external microprocessor.
Accessories for the MS5541
Also available are sample boards, which can be used together with the USB Development Kit to quickly evaluate the sensors and build prototypes, as well as light and dust protection caps.
