Altimeter Module MS5534

The MS5534 pressure measurement 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. Additionally the module contains 6 readable coefficients for a highly accurate software calibration for the pressure and temperature measurement. The MS5534 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.

MS5534-CM: protected by a metal ring filled with silicon gel on a ceramic hybrid 9x9mm (outdoor applications)

Pressure range: 0.15 ... 16 PSI abs.; operating temperature: -40 ... +125°C

MS5534-CP: protected by a plastic cap and one drop of silicon gel on a ceramic hybrid 9x9mm

Pressure range: 0.15 ... 16 PSI abs.; operating temperature: -40 ... +125°C

The MS5534-C is fully software compatible to previous versions (MS5534-A and MS5534-B)
