Absolute pressure sensor MS5561 by AMSYS

Absolute pressure sensor MS5561

The MS5561C is not recommended for new designs as it is an old version of a pressure measurement miniature sensor consisting 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. Additionally the module contains 6 readable coefficients for a highly accurate software calibration for the pressure and temperature measurement. The MS5561C 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 about refresh rate and average current consumption can individually be defined by the application software.

MS5561-C: protected by a metal cap filled with silicon gel on a ceramic hybrid 6.2×6.4mm2
Pressure range: 10…1100mbar (0.15 … 16 PSI) abs.; operating temperature: -40 … +85°C.

Accessories for the MS5561

Also available are sample boards, which can be used together with the USB Development Kit to quickly evaluate the sensors and build prototypes.

*Modules are pressure sensors, whose output signals have to be calculated by an external microprocessor.
